THE MARINE AND ESTUARINE MOLLUSCS OF THAILAND

Teerapong Duangdee; Kitithorn  Sanpanich

Thailand is a large Southeast Asian country on the margin of the biodiverse coral triangle. It has a 3,299 km coastline on both the Gulf of Thailand in the Pacific Ocean and the Andaman Sea in the Indian Ocean. An extensive literature and internet search documented over 15,000 records of 3,359 species of Thai marine and estuarine molluscs. Records of 137 species are considered to be incorrect or dubious as their known ranges do not include Southeast Asia. The remaining 3,222 species include 1,963 gastropods, 1,116 bivalves, 129 cephalopods, seven polyplacophorans and seven scaphopods; no records were found of monoplacophorans or aplacophorans. Most records cannot be verified through specimens lodged in museums. The taxonomy of all species has been updated to their current status. Previous names used, occurrence on the Gulf of Thailand and/or Andaman Sea coast, and literature records and notes (if any) are provided for each species. Two invasive species, the mussels Mytilopsis sallei (Récluz, 1849) and Mytella strigata (Hanley, 1843), are known to have been introduced to Thailand, but there may be more introduced species that have not yet been detected. Strategies to further document the marine and estuarine molluscs of Thailand are proposed.

It has a 3,299 km coastline on both the Gulf of Thailand in the Pacific Ocean and the Andaman Sea in the Indian Ocean. An extensive literature and internet search documented over 15,000 records of 3,359 species of Thai marine and estuarine molluscs. Records of 137 species are considered to be incorrect or dubious as their known ranges do not include Southeast Asia. The remaining 3,222 species include 1,963 gastropods, 1,116 bivalves, 129 cephalopods, seven polyplacophorans and seven scaphopods; no records were found of monoplacophorans or aplacophorans. Most records cannot be verified through specimens lodged in museums. The taxonomy of all species has been updated to their current status. Previous names used, occurrence on the Gulf of Thailand and/or Andaman Sea coast, and literature records and notes (if any) are provided for each species. Two invasive species, the mussels Mytilopsis sallei (Récluz, 1849) and Mytella strigata (Hanley, 1843), are known to have been introduced to Thailand, but there may be more introduced species that have not yet been detected. Strategies to further document the marine and estuarine molluscs of Thailand are proposed. 2 F. E. Wells, K. Sanpanich, S. K. Tan & T. Duangdee INTRODUCTION The Indo-West Pacific is the largest marine biogeographical province in the world. It spans the tropical oceans from about 30 degrees north of the equator to about 30 degrees south, and extends across the vast regions of the Indian and Pacific Oceans from Hawaii to the east coast of Africa. Within the Indo-Pacific, the coral triangle, from the Philippines and Malaysia to Papua New Guinea, is the most megadiverse area of the world oceans (HoeghGuldberg, 2009). Molluscs are the “insects of the sea” with by far the greatest biodiversity of the animal groups. While there is no complete inventory of the marine molluscs of any area, the Philippines have received the most scientific attention. The Philippine Islands have a rich diversity of marine habitats and an accordingly broad diversity of marine mollusc species that have long been studied, with 5,835 marine mollusc species having been documented in the country (Poppe, 2017). In contrast to the Philippines, the marine and estuarine molluscs of Thailand have been relatively poorly studied, but there have been several compilations of the phylum. Early records include: Morlet (1889) with 167 species; Lynge (1909) with 316 bivalves; and Suvatti (1937, 1938) with 270 species. Nateewathana et al. (1981) reported 548 species in the Phuket Marine Biological Center (PMBC) collection at that time; the number has grown significantly since then. The largest compilation of Thai marine and estuarine molluscs was Nabhitabhata (2009), with 1,267 species. Recently, BEDO (2017a–e) listed 1,270 species. Having been published over a span of nearly 130 years, there have been considerable taxonomic changes that make direct comparisons of the above lists difficult. Clearly the marine molluscan fauna of Thailand, with a broad diversity of habitats on both the Pacific and Indian Oceans, is much greater than indicated in the above compilations. The goals of the present book are to first compile as exhaustive a list as is possible of the scientific information on the marine and estuarine molluscs of Thailand, then to update the scientific names of the species recorded. The study will provide a basis for further scientific investigations of the group in Thailand. It is emphasised that in the absence of voucher material of most of the species in publicly accessible locations, the present paper provides only an introduction to marine and estuarine species recorded from Thailand and identifications of many of the species listed may be incorrect. Dayrat (2011) emphasised the risk of assuming such unverified literature records were correct. 16 species of the nudibranch genus Discodoris were recorded in the literature from the Mediterranean Sea until a revision of the group demonstrated that the genus is in fact absent in the area. However, the present paper provides an entry point into our understanding of the marine and estuarine molluscs of Thailand. 3 The Marine and Estuarine Molluscs of Thailand MATERIAL AND METHODS An extensive literature search, both in English and Thai, was undertaken of the marine and estuarine molluscs of Thailand, including books, journals and revisions of family and genera that might include records of species from Thailand. The Phuket Marine Biological Center (PMBC) publishes both a Research Bulletin and Special Publication series; all issues of each series were examined. In addition, all volumes of the Tropical Marine Mollusc Programme are available on the PMBC website and were searched. Molluscan journals, such as Indo -Pacific Mollusca, Monographs of Marine Mollusca, Molluscan Research and The Veliger, were also consulted. Available shell books were also examined. An extensive internet search was conducted, including Google Scholar and open repositories, i.e., ResearchGate and Academia.edu, using terms such as ‘Thailand’, and phrases associated with molluscs and the various classes. Literature cited sections of papers reporting Thai marine and estuarine molluscs were used to locate further papers. To be as inclusive as possible, grey literature was also used. The literature search concentrated on revisions of particular families and genera and faunal surveys. Other literature, such as ecological and physiological studies, are not cited unless they add to list of species recorded in Thailand. A recent development is the trend for international museums to database their collections and place the information on the web in sites such as the Global Biodiversity Information Facility (GBIF; https://www.gbif.org/). GBIF was searched to obtain currently available Thai records. As this and other facilities develop, more information will become available on the marine and estuarine molluscs of Thailand. Only taxa identified to species are included in this analysis; those identified only by family or genus are disregarded as there is no way of knowing whether species A of one author is the same as species A of another paper. The internet search turned up numerous records of Thai shells for sale by dealers; these are transitory, unverified and were not used. Every species listed in all of the publications was checked against the World List of Marine Species (WoRMS; WoRMS Editorial Board [2018]) to determine the current valid name and family placement. If a species could not be located in WoRMS Editorial Board (2019), alternative spellings, such as changing the ending from ‘-a’ to ‘-us’ or vice versa, and other generic placements were tried. Other information provided by WoRMS Editorial Board (2019) was included, such as species listed as uncertain, nomen dubium, taxon inquirendum, etc. Where this was unsuccessful, other sources were used, such as Ruhoff (1980) and other internet databases such as the Atlas of Living Australia (ALA, 2019). Over 15,000 citations to the scientific literature on Thai molluscs are provided in the list below. Some freshwater species can tolerate low salinity brackish water. This is a continuum, with each species having its own salinity tolerances. Species listed by WoRMS Editorial Board (2019) as only occurring in freshwater are not included, but freshwater species that also inhabit brackish water are listed. The higher-level systematics of molluscs are currently in a state of flux as new data, particularly genetic information, is added to our knowledge. The higher taxonomy used in this book follows WoRMS Editorial Board (2019). Because of inconsistent use across the phylum, subgenera and subspecies are not used. However, cephalopods are an exception as many papers list cephalopod subgenera. The following information is provided for each species: current scientific name including genus, species, author and date; names under which the species was previously recorded in Thailand; whether the species was recorded from the Gulf of Thailand and/or Andaman Sea coastline of Thailand; and literature references to the species in date order and notes (if any). Most changes in species taxonomy have been transfers of a species from one genus to another. Alternative names used for a species are shown so future researchers can trace the species through the various publications. Misspellings in earlier references are included for the same reason. Very minor changes, such as changes in the ending of a name from ‘-a’ or ‘-us’ or vice versa, after the gender of a species changed upon a move to another genus, or differences in the year the species was described (i.e., 1841 versus 1842), are not shown. However, if the time difference is substantial (i.e., 1841 versus 1860), it is included. In some cases, the author shown in the Thai reference is not the actual author of the species; this is also indicated. Also included are cases where the Thai reference did not give an author and date. However, full citation of each species is provided as recorded by WoRMS Editorial Board (2019). “Reported as” indicates that the species was not reported with the currently accepted name. “Also reported as” indicates that the species has been reported from Thailand using the current name but has also been reported under different names. Until very recently, the original scientific literature was essentially unavailable in Thailand, and there were few shell books available. In most cases species were, out of necessity, identified by Thai researchers based on photographs and descriptions in the shell books, often black-and-white photocopies of colour illustrations, and 4 F. E. Wells, K. Sanpanich, S. K. Tan & T. Duangdee other secondary sources. Without a knowledge of closely related species, this sometimes resulted in species being incorrectly identified as those figured in the books. We have listed these misidentifications where they were obvious in Appendix 1, but there are undoubtedly others. PMBC has a small but growing collection of species that can be examined. The Thai Natural History Museum (THNHM) is also small, and there is a mollusc collection at Kasetsart University. The rapid development of the internet and literature databases, such as the Biodiversity Heritage Library (https://www.biodiversitylibrary.org/), has recently made large portions of the original taxonomic literature much more available to all researchers. Future identifications should be based on the original descriptions, if available. Revisions of families or genera are the second preference, followed by books on Thai marine and estuarine molluscs. If books on overseas localities are used, care should be taken to ensure that the geographic range of each species includes Thailand. 5 The Marine and Estuarine Molluscs of Thailand THE MARINE AND ESTUARINE MOLLUSCS OF THAILAND MARINE AND ESTUARINE HABITATS OF THAILAND Thailand is a large country in Southeast Asia with a land area of 513,115 km 2 and a coastline of 3,299 km. It is a peninsular country lying 5–20°N and 97–106°E. Thailand has two extensive coastlines, the eastern coast located along the Gulf of Thailand in the Pacific Ocean, and the western coast facing the Andaman Sea in the Indian Ocean (Fig. 1). The Thai Exclusive Economic Zone (EEZ) in the Gulf of Thailand has an area of 304,000 km2, and the EEZ along the Andaman coast is 116,280 km2 (Chavanich et al., 2010a). The climate of coastal Thailand is tropical, with an average annual temperature of 27.6°C, ranging from a mean of 25.5°C in January to 29.9°C in April. While the average annual rainfall is 1,556 mm, it is seasonal and there is little rain during winter and summer. Average rainfall is highest in September (378.3 mm) and lowest in December (4.6 mm). The average annual relative humidity is 76.1%, varying from a low of 70.0% in January to a high of 81.4% in October (Pumijumnong, 2014). The intertidal and shallow water environments of the two coasts are similar, with extensive rocky shores, sand beaches, tidal flats, mudflats, estuaries, coral reefs, seagrass beds and mangroves occurring on both coasts (Fig. 2). There is an increasing number and variety of artificial habitats such as jetties, bridges, roads and aquaculture facilities, particularly extensive prawn farms on both coasts. Bays and islands are more numerous on the Andaman coast (Chavanich et al., 2010a). There are about 545 islands on the Andaman coast, 100 in the eastern Gulf of Thailand and 150 in the western Gulf (Phongsuwan et al., 2013). Fig. 1.

The most common marine habitats in Thailand (Photographs by: Kitithorn Sanpanich). A key difference between the two coasts is that the Gulf of Thailand is shallow, with a mean depth of 45 m and a maximum of 80 m. The bottom is largely mud. The Upper Gulf is a square-shaped area at the northern end, with four major rivers emptying into it. The Chao Phraya River is the largest, with an annual average flow of 13,220 km3. The Lower Gulf has two ridges on its southern margin that restrict water flow into and out of the South China Sea (Wattayakorn, 2006). The Gulf is influenced by the southwest monsoon from May to September and the northeast monsoon from October to February (Phongsuwan et al., 2013). In contrast, there is a narrow continental shelf on the Andaman coast, up to 100 km wide, that gives way to a steep continental slope that reaches a depth of up to 2,000 m. Intertidal rocky shores and sand beaches are found on both coasts. 7 The Marine and Estuarine Molluscs of Thailand There is an estimated 153 km2 of coral reefs in Thailand, with three reef types occurring: coral communities with no true reef structure; developing fringing reefs; and early formation of fringing reefs (Yeemin et al., 2001). In the Andaman Sea, coral reefs usually occur as fringes in clear water on the eastern sides of islands where they are sheltered from the southwest monsoon. In the eastern Gulf of Thailand, coral reefs are most common on the east and north coasts of islands where they are sheltered from the southwest monsoon. The northeast monsoon is more influential in the western Gulf, and reefs there are most common on the west and south coasts. Rocky shores dominate on the windward side of most islands (Phongsuwan et al., 2013). As with many other parts of the world, Thai coral reefs have been heavily stressed by human activity, which includes direct destruction of reefs, and indirect effects such as pollution and nutrient enrichment. The effects of tourism, with trampling and inadvertent destruction of fragile reef structures, are particularly evident in Thailand. There have been several severe bleaching events, with a substantial bleaching occurring in 2010. Several outbreaks of the crown of thorns starfish have occurred on reefs in the Andaman Sea, particularly in the 1980s. The Indian Ocean tsunami on 26 December 2004 significantly affected coral reefs on the Andaman coast; while about 40% of surveyed reefs had no visible damage, 47% had low-to-moderate impacts and 13% were severely damaged. However, surveys taken two years after the tsunami showed a slightly higher coverage of live coral than surveys two years before the tsunami (Phongsuwan et al., 2013). Extensive, diverse, and biologically productive (74 known mangrove species) mangrove forests are a key intertidal habitat in Thailand. Mangroves are common on the muddy tidal flats at river mouths. There are extensive mangroves on the Andaman coast, particularly in Phang Nha province, which has 18.5% of the total mangrove area of Thailand. Mangroves are common along the east coast of the Gulf of Thailand and along the Chao Phraya River delta near Bangkok. The mangrove forests often have two layers. The upper storey grows to a height of 20 m or more, with large trees of Rhizophora, Bruguiera, Heritiera and Xylocarpus. Common understorey species are in the genera Bruguiera and Ceriops. The palm Nypa fruticans is common along the edges of intertidal creeks (Pumijumnong, 2014). There has been a considerable loss of mangroves in Thailand for a variety of reasons, including logging, pollution, etc. The primary cause of losses is the removal of mangroves to create space for shrimp farms. Levees are built to a height of 1–1.5 m to increase the water volume available for the shrimp. Unfortunately, the ponds become unviable after about five years and are abandoned. The levees change water flow patterns and restrict recolonisation of the ponds by mangroves, even if they are actively planted. There were about 320,000 ha of mangroves in Thailand in 1975, but this was halved by 1996. Conservation and rehabilitation increased the mangrove area to about 240,000 ha by 2004 (Pumijumnong, 2014). Seagrass habitats in Thailand have been classified into three categories: mangrove–associated beds, shallow sandy–bottom beds and coral reef-associated beds (UNEP et al., 2005). There are 12 species of seagrasses in Thailand in the genera Halophila, Cymodocea, Halodule, Enhalus, Thalassia, Syringodium and Ruppia. 11 species have been recorded from both coasts; Ruppia maritima is known only from the Gulf of Thailand. The area of seagrasses is much larger and denser on the Andaman coast (9,448 ha) than in the Gulf of Thailand (5,489 ha) (Adulyanukosol & Poovachiranon, 2007). There is a distinct seasonality of seagrasses in Thailand. For example, Khogkhaoa et al. (2017) studied the spatial distribution of seagrasses and their biomass in relation to a number of physical factors near the mouth of the Trang River on the Andaman Coast. 10 species with a total area of 61 km2 were found during the dry season, nearly half (29 km 2) of which was Halophila decipiens. The other common species were Enhalus acoroides and Halophila ovalis. Only eight species with a total area of 24 km2 were found in the rainy season. The most important limiting factors were water depth and light intensity. The marine algal flora is diverse, with about 326 species having been recorded: 98 chlorophytes, 56 phaeophytes and 172 rhodophytes. The number of blue green algae has not been determined (Coppejans et al., 2010, 2017). Marine algae are abundant in a wide range of shallow water habitats, including rocky shores and artificial hard surfaces, and as epiphytes on seagrasses and mangroves. HISTORY OF MOLLUSC EXPLORATION IN THAILAND According to Hylleberg (2013), the first extensive sampling of benthic species in the Gulf of Thailand was undertaken in early 1900 by the Danish Expedition to Siam, funded by the Danish government and the Carlsberg Foundation. There were only two scientists, the botanist Johs Schmidt and the echinoderm specialist Theodor Mortensen. Koh Chang Island in the eastern Gulf of Thailand was used as a base with Mortensen undertaking boat trips of up to a week from Koh Chang for dredging and intertidal collecting. Unfortunately, with the large number of rivers in the region, the bottom was predominately mud and Mortensen had considerable difficulty in locating suitable habitats for dredging. Specimens collected were deposited in the Zoological Museum, Copenhagen. Bergh (1902) published on opisthobranchs and Lynge (1909) reported on bivalve molluscs collected during the expedition. 8 F. E. Wells, K. Sanpanich, S. K. Tan & T. Duangdee Three additional Thai–Danish expeditions to Thailand were undertaken in the following decades, but these were primarily botanical. The Fifth Thai–Danish Expedition in January to March 1966 was originally conceived as a botanical expedition, but in 1961, Germany had initiated successful trawl fisheries in the Gulf of Thailand. Therefore, the Thai Department of Fisheries was interested in exploring the fisheries resources of the Andaman coast and made their new research vessel M/S DHANARAJATA available for the expedition. The survey evolved into a combined terrestrial botanical and marine biological expedition that included 15 Thai scientists and students from the departments of Fisheries and Agriculture in Chulalongkorn University, and four Danish scientists and representatives from the UNESCO office in Singapore, Singapore Botanic Gardens and the Allan Hancock Foundation in California. The eminent Danish scientist Gunnar Thorson led the marine biological component of the expedition. Its goals were: 1) research work on fish-food animals on sediment bottoms from a quantitative point of view; 2) training of groups of young Thai marine biologists; and 3) the creation of a broad reference collection of marine fauna for use by the Thai Marine Fisheries Laboratory in the future education of marine and fishery biologists (Seidenfaden et al., 1968). A key result of the expedition was the development of a concept for the creation of the Phuket Marine Biological Center. The Thai–Danish team examined 10 sites on Phuket Island for the possible construction of a marine laboratory. The variety of habitats that could be reached by boat or vehicle within 30 minutes, including coral reefs, rocky shores, open and sheltered sandy beaches and mangroves, led to the present site of PMBC being chosen. An agreement for the development of PMBC was signed by the Royal Thai and Danish governments in October 1968 (Seidenfaden et al., 1968). The Thai government paid for the buildings and other infrastructure while the Danish contribution was scientific equipment, staff training, and expert assistance. Jørgen Hylleberg was appointed as the Danish Advisor, a role that he fulfilled from 1979 to 1994. Hylleberg then became project director for the new Tropical Marine Mollusc Programme (TMMP) and continued to advise PMBC until TMMP funding was ended by the Danish International Development Agency (DANIDA) in 2004 (Hylleberg, 2013). The creation of PMBC opened a new era in Thai marine research that was primarily focused on discovering the biodiversity of marine and estuarine biota on the Andaman coast; much of the work was on molluscs. A new building was opened in 1983 to house the rapidly growing Reference Collection. PMBC started two journals, the Research Bulletin and Special Publications, both of which contain a significant number of papers on molluscs. The two series provided venues for PMBC and other scientists, from both Thailand and overseas, to publish scientific information on the Thai marine environment. The journals are sent in exchange for publications from other national and international institutions, thus enhancing the PMBC library (Hylleberg, 2013). Facilitating the education of young scientists has been a key PMBC outcome. A number of field courses have been presented at PMBC and PMBC staff have been able to participate in overseas opportunities. Particularly successful has been the ability of Thai scientists to obtain advanced degrees in Denmark. Mollusc workers include Charatsee Aungtonya, Anuwat Nateewathana and Vararin Vongpanich with MSc degrees from the University of Aarhus; Anuwat Nateewathana continued on to get a PhD from the same university. Charatsee Aungtonya obtained a PhD at the University of Copenhagen. The transfer of students worked both ways, with students from the University of Aarhus undertaking their field studies at PMBC. The mollusc workers among these include Michael Bech, Britt Gribsholt and Peter Middlefart (Hylleberg, 2013). The TMMP, coordinated by Jørgen Hylleberg, was established in 1991 as a joint research activity between Thailand and other Southeast Asian countries. Annual workshops were held, which allowed participants to present papers and interact with other participants in a week-long conference, then to undertake field excursions. Denmark, India and Thailand participated in the first year of the TMMP. The first conference was devoted to the possible aquaculture of the large Murex ramosus. Indonesia joined in 1992. Over time the number of participants and the range of scientific topics grew rapidly. The quantity of biodiversity information presented increased so much that from 1997 onwards an entire volume of the workshop proceedings was devoted to biodiversity studies. Each annual workshop was held in a different Southeast Asian country, increasing the ability of scientists in the region to participate. The opportunity to meet at a workshop and exchange scientific information led to numerous cooperative projects among the participants. By the time the programme was terminated in 2004, the TMMP had published 11 sets of proceedings and two monographs. Mollusc researchers from 57 institutions in 22 countries had participated in the various workshops. Research presented concentrated on the Indian Ocean and South China Sea in Thailand, Cambodia, Vietnam, India and Indonesia. A number of mollusc experts from other Asian countries, Europe, South Africa, United States and Australia also participated in the TMMP, considerably broadening the TMMP outlook (Hylleberg, 2013). An ambitious project, Biodiversity of the Andaman Sea Shelf (BIOSHELF), was undertaken from 1996 to 2000 on the Andaman coast of Thailand to survey marine biodiversity along the entire Thai coastline from the Myanmar 9 The Marine and Estuarine Molluscs of Thailand border in the north to Malaysia in the south. Extensive benthic surveys were made using a variety of grabbing and trawling techniques down to 1,000 m and open water species to deeper dept hs. A total of 98 stations were conducted on 12 transects between 40 and 900 m, and an additional 16 stations in the Thai EEZ. 19 nearshore stations were made (Aungtonya et al., 2000; Tendal et al., 2014). Specimens collected were deposited in the PMBC Reference Collection. Extensive reports were compiled on the crustaceans (Bruce et al., 2002) and polychaetes (Eibye–Jacobsen, 2002), but only limited information on molluscs was published: Schwabe (2006) on chitons and Jensen (2007) on opisthobranchs. In addition to the Danish work in Thailand cited above, there have been a number of major oceanographic expeditions that have worked in Thai waters for at least part of their extensive voyages. Again, Danes played a leading role. The Thai component of these expeditions was summarised by Jensen & Knudsen (2001). The DANA circumnavigated the world from 1928 to 1930. The expedition was focused on plankton, fish and oceanography. It was in Thai waters in April and May 1929. The expedition was led by the Danish scientists Johs Schmidt and Anton Bruun. The GALATHEA expedition, undertaken from 1950 to 1952, was led again by Anton Bruun. It worked in the Gulf of Thailand in June 1951. Unfortunately, the focus of the expedition was on the deep sea, so the Gulf of Thailand molluscs were not included. The Naga Expedition, also led by Anton Bruun, worked in Thailand in 1959. Included among the scientists was the prominent malacologist Jørgen Knudsen. More recently, a workshop on the systematics, anatomy and natural history of shallow water marine bivalves was held in Kungkrabaen, Chanthaburi Province, in August and September 2005 (Bieler et al., 2008a). The primary goal was to increase scientific knowledge of marine bivalves in the eastern Gulf of Thailand, but associated work was also undertaken on gastropods. Thai and international scientists conducted field studies in Kungkrabaen for two weeks, then returned to their home institutions to complete the associated laboratory studies and write their papers describing the results. A special volume of the Raffles Bulletin of Zoology contains the workshop results in 17 papers (Bieler et al., 2008b). Since the completion of the Kungkrabaen workshop, primary development of scientific information on Thai marine molluscs has resulted from short-term studies of particular areas such as marine parks. Most of the work has been undertaken by Kitithorn Sanpanich of Burapha University and Teerapong Duangdee of Kasetsart University. OVERVIEW OF SPECIES RECORDED The present compilation presents records of 3,359 marine and estuarine species in Thailand. 137 species are rejected or considered dubious: 105 on geographic grounds because the species does not occur in the Southeast Asian marine biogeographic region (Appendix 1); 26 on a taxonomic basis; four for being fossils; and two for being freshwater species. The remaining 3,222 species (Table 1; Fig. 3) are considered valid by WoRMS Editorial Board (2019) and other sources. The compilation provides an up-to-date understanding of our knowledge of the marine and estuarine molluscs of Thailand, and a basis for future research on the phylum in Thailand. However, individual records should be treated with scepticism as most cannot be verified by examination of the original specimens and compared with other material. The PMBC collections are an exception as they are available, as are the collections at Kasetsart University and THNHM. Table 1.

Examples of marine mollusc species recorded in Thailand (Photographs by: Kitithorn Sanpanich). 11 The Marine and Estuarine Molluscs of Thailand The 3,222 species recorded from Thailand are obviously an incomplete representation of the phylum in Thailand. Most of the species recorded are gastropods (1,963) and bivalves (1,116) (Table 1), but even in these groups, there are undoubtedly many species that have yet to be recorded. Because of their economic importance, cephalopods are the best-studied group in the country; we found literature references to 129 species. However, there are still more species to be recorded. Polyplacophorans (7) and scaphopods (7) are poorly studied; no records were encountered of monoplacophorans or aplacophorans. INTRODUCED SPECIES OF MARINE AND ESTUARINE MOLLUSCS There is an increasing awareness worldwide of the numbers of marine species being introduced from one part of the oceans to another. For example, over 250 species are known to have been introduced into Australia (NIMPIS, 2017). Most of these species are apparently innocuous, causing no harm in their new environment. However, a small proportion become invasive marine species (IMS) that can cause considerable environmental and economic damage by changing ecosystems, outcompeting native species, threatening fisheries and aquaculture, introducing diseases and interfering with industrial facilities (Johnson & Chapman, 2007; Molnar et al., 2008; Wells et al., 2009; Crowe & Frid, 2015). Of the 250 species introduced into Australian waters, only about a dozen are regarded as IMS (NIMPCG, 2009a, 2009b; NIMPIS, 2017). There has been no comprehensive examination of introduced marine and estuarine species in Thailand. Understanding the Thai situation is made more difficult because of the many centuries that wooden boats were used to transport goods and people within Southeast Asia and beyond. Species may have been introduced hundreds of years ago that now appear to be native. The problem has been exacerbated in recent decades by the globalisation of shipping, which allows vessels to rapidly move from one area of the world’s oceans to another. Thailand has two major ports that can serve as primary recipient areas for introduced marine species. Both are in the inner Gulf of Thailand. Laem Chabang is the larger. It handled 13,313 vessels in 2017 and has extensive support facilities such as drydocks and a floating drydock (LCP, 2018). In fiscal year 2016, Bangkok Port handled 3,067 vessels with 21 million tonnes of cargo (PAT, 2020). There are also other ports that handle smaller numbers of international vessels. In a survey of introduced marine species in Southeast Asia, Chavanich et al. (2010a) recorded only seven introduced species in Thailand, but emphasised that there has been no survey conducted in the country. The low number known from Thailand is probably a reflection of the lack of study, but also may reflect a relatively low number of introductions. Only one of the seven species reported in Thailand by Chavanich et al. (2010a) was a mollusc, the false mussel Mytilopsis sallei (Récluz, 1849) (reported as Mytilopsis adamsi Morrison, 1946), which has been recorded in the Songkla Lakes in the south of the country (Wangkulangkul & Lheknim, 2008; Wangkulangkul, 2018). Mytilopsis sallei has been reported in numerous Asian countries, including India (Kalyanasundaram, 1975), Japan (Habe, 1980; Furuse & Hasegawa, 1984), Hong Kong (Morton, 1980, 1989; Huang & Morton, 1983), Taiwan (Chang, 1985), Singapore (Tan & Morton, 2008) and China (Cai et al., 2014). Wangkulangkul (2018) recently surveyed the population of Mytilopsis sallei in the Songkla Lakes and found the species to be well established. However, it is most abundant in the rivers flowing into the lake where the water is about 15 parts per thousand (ppt). It is much less common in the higher-salinity parts of the lakes system. The fact that Mytilopsis sallei became established in Songkla Lakes emphasises the point that concern about IMS in Thailand is not restricted to the major ports of Bangkok and Laem Chabang. Sanpanich & Wells (2019) recently reported that the species has now been found in the inner Gulf of Thailand, again in lower-salinity areas. Chavanich et al. (2010a) did not record the Central American mussel Mytella strigata (Hanley, 1843) (previously known as Mytella charruana [d’Orbigny, 1842]) in any Southeast Asian country. However, it has recently become invasive in the Philippines (Rice et al., 2016; Mediodia et al., 2017; Vallejo, 2017), Singapore (Lim et al., 2018) and India (Jayachandran et al., 2019). Sanpanich & Wells (2019) surveyed the inner Gulf of Thailand and found the species to be widespread, with densities of up to 40,000 m −2. In Singapore, Lim et al. (2018) expressed concern that the species might be outcompeting the economically important Asian green mussel, Perna viridis (Linnaeus, 1758), a concern shared for the Thailand populations by Sanpanich & Wells (2019). Sanpanich & Wells (2019) reported anecdotal information that Perna viridis is being grown in aquaculture farms in the Phuket area on the Andaman coast. The species is uncommon in the region, and seed stock are being transferred from Sri Racha on the Gulf of Thailand to Phuket, providing a direct mechanism for the possible introduction of Mytella strigata to the Andaman coast. Two other bivalve species have been introduced to Asia that should be mentioned; neither has yet been recorded in Thailand. The mussel Brachidontes striatulus (Hanley, 1843) was introduced to Singapore over a decade ago. 12 F. E. Wells, K. Sanpanich, S. K. Tan & T. Duangdee Densities of up to 75 per 100 cm2 were found in salinities ranging from 12 to 20 ppt (Morton & Tan, 2006). The Australian mussel Xenostrobus securis (Lamarck, 1819) has been introduced to European waters and also Japan (Kohama et al., 2001; Iwasaki & Yamamoto, 2014) and Hong Kong (Morton & Leung, 2015). Brachidontes pharaonis (Fischer, 1870) is a small mytilid mussel whose native range is the western Indian Ocean and Red Sea. However, in 1876, just seven years after the Suez Canal was opened, the species was found at Port Said on the Mediterranean coast of Egypt (Dogan et al., 2007). Brachidontes pharaonis was first discovered along the Israeli coast in 1937, and was still rare in the early 1970s. However, a survey 30 years later found dense populations on rocks, where it was the dominant species (Galil, 2000). It has become invasive in many parts of the Mediterranean (Terranova et al., 2006; Cilia & Deidun, 2012). The taxonomy of the species has been confused by the close resemblance of the shells of Brachidontes pharaonis to those of the Indo-Pacific Brachidontes variabilis (Krauss, 1848). Lamy (1936) and Huber (2010) considered the two to be conspecific and recognised the proper name as Brachidontes pharaonis. This was followed in Thailand by Swennen et al. (2001) and Nabhitabhata (2009) (see Appendix 1). Brachidontes variabilis has also been reported in Thailand by Nateewathana et al. (1981), Bussarawit (1995), Aungtonya et al. (1999), Nabhitabhata (2009) and BEDO (2017b). However, GBIF (2019) regards the two as separate species and Brachidontes variabilis as the native Thai species. Two of the species in Appendix 1 warrant further consideration for possibly occurring in Thailand. The eastern American mud snail Tritia obsoleta (Say, 1822) has been introduced into California, where it is very abundant in San Francisco Bay. It was possibly introduced in association with the transplantation of oysters for aquaculture (Carlton, 1992; GISD, 2015a). There is no evidence of Tritia obsoleta in Thailand, and it is likely to have been misidentified. The European oyster Ostrea edulis (Linnaeus, 1758) has been introduced into a number of countries, including: Australia, Canada, Fiji, Israel, Japan, Mauritius, Namibia, New Zealand, South Africa, Tonga and the United States (Carlton, 1992; GISD, 2015b). It has been reported from Thailand by Suvatti (1937, 1938) and Duangdee et al. (2011) (Appendix 1), but was not included by Bussarawit & Cedhagen (2010) in their revision of Thai oysters. The species has been reported from southwestern Australia using genetic techniques (Morton et al., 2003). A genetic analysis would be required to demonstrate Ostrea edulis is present in Thailand. FISHERIES IMPORTANCE OF THAI MOLLUSCS Thailand is one of the largest producers of seafood products in the world. It is an important industry for the country. Over 30 species of molluscs, predominately cephalopods, are important in the commercial catch. The production can be divided into wild-caught fisheries and aquaculture. Derrick et al. (2017) reported that Thai catches from Thailand’s EEZ increased from approximately 400,000 tonnes in 1950 to 2.6 million tonnes in 1987. The catch then declined to 1.7 million tonnes in 2014. However, Derrick et al. (2017) analysed the catch statistics and concluded that because of under reporting the actual catch may have been three times greater. A survey in 2000 reported that 58,119 fishing boats were in use in Thailand. Most (80%) were small local boats; many were at or near the subsistence level. 20% of the boats were >5 tonnes and capable of undertaking voyages ranging upwards from a full day to several weeks. About 60% of the catch was made in Thai waters (41% from the Gulf of Thailand and 19% from the Andaman Sea). The total catch in 2007 was 2.2 million tonnes valued at 63 billion Baht (about USD $2 billion). Cephalopods contributed 6% of the total 2007 fisheries catch, while other molluscs were 1% (FAO, 2019). Not included in this survey was hand collecting along the shoreline, much of which was for molluscs, particularly bivalves. Ngamprasertkit (2018) reported that wild-caught squid and cuttlefish in 2017 were worth USD $345 million. Other molluscs added another USD $374 million. The total wild catch in 2015 was 1.32 million metric tonnes, with squid contributing 91,000 tonnes and other molluscs 16,700 tonnes. Squids, cuttlefishes and octopuses are all commercially exploited in Thailand. The key squid are four species of Loligo, Loliolus sumatrensis and Sepioteuthis lessoniana. The most important cuttlefish are five species of Sepia and Sepiella inermis. The dominant octopus are Amphioctopus membranaceus, A. aegina and Cistopus indicus (FAO, 2019). There are also small wild-caught fisheries for the short-necked clam Paratapes undulatus, scallops such as Amusium pleuronectes, and the razor clam Solen strictus (Chalermwat et al., 2003). Thai aquaculture is dominated by shrimp production, which constitutes over 90% of the total value, which was USD $1.75 billion in 2007. Molluscan aquaculture in that year totalled 362,800 tonnes, 76% of which was the Asian green mussel (Perna viridis) (FAO, 2019). The green mussel has been cultured in Thailand for over 60 years using three methods: bamboo poles, rope culture and raft culture (Keawtawee et al., 2018). Chalermwat et al. (2003) 13 The Marine and Estuarine Molluscs of Thailand divided Thai molluscan aquaculture into two methods: species produced through traditional aquaculture techniques without associated hatcheries and species obtaining stock from hatcheries. Yang et al. (2019) reported that Thai aquaculture production is among that of the top 10 nations worldwide, with 1.45% of global production. In 2012, Thai molluscan aquaculture totalled 205,192 metric tonnes. The most important species were: green mussels (Perna viridis), 107,229 tonnes; blood cockles (Anadara granosa), 71,450 tonnes; oysters (Crassostrea spp.), 26,508 tonnes; European flat oysters (Ostrea edulis), 4 tonnes; and abalone (Haliotis spp.), 5 tonnes. Small quantities of horse mussels (Modiolus spp.) were also grown but not reported (Yang et al., 2019). According to Chalermwat et al. (2003), the key species of oysters are Saccostrea cucullata, Crassostrea belcheri and Crassostrea iredalei. Ngamprasertkit (2018) reported that total marine aquaculture in Thailand in 2017 was 508,700 tonnes. The dominant molluscs in that year were Asian green mussels (Perna viridis) at 115,500 tonnes, blood cockles (Anadara granosa) at 59,000 tonnes, and oysters at 19,900 tonnes. Green mussels and blood cockles typically constitute over 80% of the total cultured shellfish harvest by weight, but the relatively small oyster harvest is much more valuable and provides almost 50% of the total annual farmed shellfish crop value (Chalermwat et al., 2003). The horse mussel Arcuatula arcuatula is produced in small quantities for animal feed and, at the time of the report, aquaculture for the abalone Haliotis asinina and the spotted babylon Babylonia areolata were being developed (Keawtawee et al., 2018). COMPARISON OF THE MOLLUSCS OF THE GULF OF THAILAND AND THE ANDAMAN SEA The total number of species recorded from the Gulf of Thailand (2,494) was slightly more than the 2,400 recorded from the Andaman Sea. 61 species have been recorded from Thailand without either coastline being specified. About 44% of the species (1,524) have been recorded from both coastlines, demonstrating a considerable overlap of widespread Indo-Pacific species. The high degree of overlap in mollusc species found on the two coasts is consistent with the finding of Wells (2002), who recorded a very high overlap between the molluscs of the eastern Indian Ocean and the western Pacific Ocean. Further collecting in Thailand would be expected to increase the number of species in common on the two coasts as many species have been recorded in only one or two papers. The two Thai coastlines are very different, particularly in the absence of deep water in the Gulf of Thailand. Collecting on the Andaman coast appears to have been more extensive through the long–term work of PMBC. On the other hand, there are more institutions and diffuse collecting efforts in the Gulf of Thailand. As there is no way of quantifying collecting effort, it is uncertain whether molluscan biodiversity in the two regions is similar. Because of their economic importance, cephalopods have been the most thoroughly studied class. 94 species have been recorded from the Gulf of Thailand and 106 from the Andaman coast (Table 1), suggesting the latter may have a slightly greater biodiversity. SUGGESTIONS FOR FUTURE RESEARCH The lack of detailed information on the marine and estuarine molluscs of Thailand prevents an accurate estimation of the number of species in the country, or on either of its coasts. This lack of basic biodiversity information is the most pressing research requirement for our understanding of Thai marine and estuarine molluscs. Fortunately, there has been a great deal of survey work undertaken in recent decades. We have highlighted above studies that have been undertaken but where the molluscs have not been published, such as the original Thai–Danish expedition in 1900, the Fifth Expedition in 1966, and the 1996–2000 BIOSHELF expedition. Specimens from these studies are deposited either in PMBC or the Statens Naturhistoriske Museum, Copenhagen, Denmark. Identification and publication of the materials in these collections would contribute substantially to our knowledge of Thai marine molluscs in a cost-effective manner. Once this material is collated and published, additional field surveys could be undertaken to further document the group in Thailand. The Kungkrabaen workshop (Bieler et al., 2008a) and similar workshops in Singapore (e.g., Tan & Goh, 2016) and Australia (e.g., Wells et al., 2003) provide a format for undertaking such surveys, and PMBC provides a natural location for a workshop. The format is simple. A small local organising committee selects the venue and organises facilities. Accommodation and meals could be provided either at PMBC or in a nearby venue; these would need to be inexpensive. Basic laboratory facilities, vehicles, boats, samp ling equipment, research permits, etc. would be provided by PMBC. International and Thai scientists would be invited to participate in the workshop. The scientists would concentrate on taxonomy, though basic field ecology and related subjects could also be researched. Thai graduate students could be selected to work with the team at the field location. The field workshop would be held for about 18 days and be targeted to coincide with two spring low tide periods. The organising committee would be responsible for all logistical aspects. Once the venue and timing have been organised, the international researchers can be invited. 14 F. E. Wells, K. Sanpanich, S. K. Tan & T. Duangdee The international researchers would be expected to arrange their own transport to the site and contribute to the cost of the workshop through a registration fee that would cover the costs of accommodation, meals and some of the other workshop expenses. In return, the international researchers would be afforded the opportunity to conduct research in their area of expertise in an overseas location with local scientists, and have all logistical aspects organised for them, including the necessary collecting and export permits. Holotypes and a selection of paratypes of any new species described and representative samples of species collected would be deposited in PMBC. If sufficient paratypes and other specimens are available, they could be deposited in THNHM and the taxonomist’s home institution. Two years should be allowed for the international scientists to obtain funding for their participation. All participants would be expected to publish one or more papers reporting their results in a joint volume, such as the PMBC Special Publication series. Alternatively, papers could be published in international journals and cite the workshop as part of a numbered series. Three years should be allowed for completion of laboratory studies, writing up of papers, and the reviewing process. Thus, the workshop would be a five-year project. PMBC is an obvious location for a workshop, but there are a number of other possible venues in Thailand. Grant support can be sought to lower the cost to participants and enhance the workshop and/or publication. It should be noted that the workshop format would work equally well for other taxa, either as independent workshops or as multidisciplinary surveys. Much of the impetus for the Fifth Thai–Danish Expedition 1966 was a requirement by the Thai Department of Fisheries to understand the food chains that support commercially valuable fisheries (Seidenfaden et al., 1968). As molluscs are the most diverse phylum in the marine environment and many species are ecologically and/or economically important, a better understanding of the biodiversity and distribution of molluscs in Thailand is required to support fisheries science. 15 The Marine and Estuarine Molluscs of Thailand LIST OF THAI MARINE AND ESTUARINE MOLLUSCS Class Bivalvia Subclass Heterodonta Infraclass Archiheterodonta Order Carditida Superfamily Carditoidea Family Carditidae Beguina semiorbiculata (Linnaeus, 1758).

Order Ostreida Superfamily Ostreoidea Bussarawit & Cedhagen (2010) reported that previous studies on oysters of the families Gryphaeidae and Ostreidae in Thailand are scarce and there is considerable confusion regarding the scientific names. Inconsistent taxonomic classification renders most of the published information uncertain. In some cases, unidentified or misidentified oysters (Nielsen, 1976; Tantanasiriwong, 1979) were preserved in the PMBC collection so that it was possible for Bussarawit & Cedhagen (2010) to revise them. The list presented here of the two families follows Bussarawit & Cedhagen (2010) with the taxonomy updated according to WoRMS Editorial Board (2019).

The present book is a summary of their work. John Taylor of the Natural History Museum, London, kindly examined an earlier version of the lucinid section and added unpublished results from a survey of marine molluscs in Ranong. Andreia Salvador of the Natural History Museum, London, provided access to the museum’s extensive molluscan library. In Perth, Lisa Kirkendale and Corey Whisson of the Western Australian Museum also provided access to important references. Three reviewers made excellent comments on the draft manuscript and we appreciate their assistance. Ng Ting Hui and Cai Peixuan of the National University of Singapore provided essential advice in preparing the manuscript for publication.

Tan & T. Duangdee APPENDIX Appendix 1. Species recorded in the literature from Thailand that are rejected or are considered to be doubtful. Class Bivalvia Family Anatinellidae Raeta meridionalis Tate, 1889. Gulf of Thailand, Andaman Sea. Reported by: Nabhitabhata (2009), Sanpanich (2011). Justification: Geography. Harry (1969) lists this species as being of uncertain status, but it is a southern Australian species, with a type locality of Middle Harbour, South Australia. Family Arcidae Anadara trapezia (Deshayes, 1840). Gulf of Thailand. Reported by: Nabhitabhata (2009). Justification: Geography. An eastern Australian species (ALA, 2020; AMS, 2020). Mosambicarca mosambicana (Bianconi, 1856). Reported as: Anadara mosambicana (Bianconi, 1850). Gulf of Thailand. Reported by: Vongpanich (1996), Aungtonya et al. (1999), Nabhitabhata (2009). Justification: Taxonomy. Vongpanich (1999) corrected the identification to Anadara sp. but did not identify it to species. Scaphula pinna Benson, 1856. Gulf of Thailand, Andaman Sea. Reported by: Vongpanich (1996), Carpenter & Niem (1998), Sanpanich (1998), Aungtonya et al. (1999), Robba et al. (2002, 2003), Wells (2005), Kasetsart University (2006), Duangdee (2007), Printrakoon et al. (2008), Nabhitabhata (2009), Galli (2015). Justification: WoRMS Editorial Board (2019) lists this as a freshwater species. Family Donacidae Donax acuticarinatus Sowerby, 1866. Gulf of Thailand. Reported by: Bertin (1881), Serène (1937), Suvatti (1938), Nabhitabhata (2009). Justification: Geography. A junior synonym of the eastern Pacific Donax carinatus Hanley, 1843 (Signorelli & Printrakoon, 2020). Donax variabilis Say, 1822. Andaman Sea. Reported by: BEDO (2017a). Justification: Geography. East coast of the United States (Mikkelsen, 1985; Adamkewicz, 1989). Family Galeommatidae Scintilla dubia (Deshayes, 1856). Also reported as: Scintilla duia (Deshayes, 1856). Andaman Sea. Reported by: Lützen & Nielsen (2005), Hylleberg & Aungtonya (2013), BEDO (2017a). Justification: Geography. Coan & Scott (2012) noted that the record from Phuket by Lützen & Nielsen (2005) is probably in error. The holotype from Ecuador is figured in Coan & Scott (2012). Family Lucinidae Anodontia edentula (Linnaeus, 1758). Also reported as: Lucina (Thyasira) edentula Linnaeus, 1758. Gulf of Thailand, Andaman Sea. Reported by: Lynge (1909), Nateewathana et al. (1981), Bussarawit (1995), Carpenter & Niem (1998), Aungtonya et al. (1999), Swennen et al. (2001), Robba et al. (2002), Duangdee (2004), Duangdee et al. (2007, 2009, 2011), Nabhitabhata (2009), BEDO (2017a). Justification: Taxonomy. Taylor & Glover (2005) recommended abandoning the use of Anodontia edentula as there is no Linnean type and the description is brief and could be any species. Most references are to Pegophysema philippiana (Reeve, 1850). Anodontia pila (Reeve, 1850). Gulf of Thailand, Andaman Sea. Reported by: Nabhitabhata (2009), BEDO (2017a). Justification: Taxonomy. Anodontia pila was synonymised with the Atlantic Anodontia alba Link, 1807, and the species is actually Cryptophysema vesicula (Gould, 1850) (see Taylor & Glover, 2005). Cardiolucina crassilirata (Tate, 1887). Reported as: Linga crassilirata (Tate, 1887). Gulf of Thailand, Andaman Sea. Reported by: Nabhitabhata (2009), Sanpanich (2011), Duangdee et al. (2013b). Justification: Geography. A southern Australian species (ALA, 2019). Ctena gunnamatta (Iredale, 1930). Reported as: Epicodakia gunnamatta Iredale, 1930. Andaman Sea. Reported by: Nabhitabhata (2009), Duangdee et al. (2011), Sanpanich (2011). Justification: Geography. The type locality for this species is Gunnamatta Bay in southern Sydney, New South Wales, Australia, at a latitude of 38°S, a temperate region. ALA (2019) does not have any records of the species. Epicodakia consettiana Iredale, 1930. Reported as: Codakia minima Tension Woods, 1875. Gulf of Thailand. Reported by: Lynge (1909), Nabhitabhata (2009). Justification: Geography. Codakia minima Tension Woods, 187 The Marine and Estuarine Molluscs of Thailand 1875, was described from Tasmania. Iredale (1930) provided a new name, Epicodakia consettiana Iredale, 1930, when recording the species from New South Wales. It is a southern Australian species (ALA, 2019). Lucinoma heroica (Dall, 1901). Andaman Sea. Reported by: BEDO (2017a). Justification: Geography. A deepwater species from the Pacific coast of Mexico (J. Taylor, pers. comm.). Family Mactridae Mactra pura Reeve, 1854. Gulf of Thailand. Reported by: BEDO (2017a). Justification: Geography. A southeastern Australian species (MRGV, 1984). Mactra cf. westralis Lamprell & Whitehead, 1990. Gulf of Thailand. Reported by: Gemert (2003). Justification: Geography. Endemic to Western Australia (Lamprell & Whitehead, 1990). Family Mesodesmatidae Paphies australis (Gmelin, 1791). Andaman Sea. Reported by: BEDO (2017a). Justification: Geography. Endemic to New Zealand (ALA, 2020).

Brachidontes pharaonis (Fischer, 1870). Gulf of Thailand. Reported by: Swennen et al. (2001), Nabhitabhata (2009). Justification: Taxonomy. Brachidontes pharaonis is native to the Red Sea. The Thai references are likely to be a misidentification of Brachidontes variabilis (Krauss, 1848). Brachidontes rostratus (Dunker, 1857). Andaman Sea. Reported by: Nateewathana et al. (1981), BEDO (2017a). Justification: Geography. A southeastern Australian species (ALA, 2020). Family Mytilidae Lithophaga antillarum (d’Orbigny, 1853). Reported as: Lithophaga straminea Dunker, 1880. Gulf of Thailand. Reported by: Lynge (1909), Nabhitabhata (2009). Justification: Geography. Occurs in the Caribbean Sea and Gulf of Mexico (WoRMS Editorial Board, 2019). Modiolaria opifex Philippi, 1841. Gulf of Thailand. Reported by: Lynge (1909), Nabhitabhata (2009).

Gulf of Thailand, Andaman Sea. Reported by: Duangdee et al. (2011), Sanpanich & Duangdee (2013). Justification: Geography. Southern Australia (Wilson, 1993). Hybochelus triangularus A. Adams. Andaman Sea. Reported by: Tantanasiriwong (1978), Nateewathana et al. (1981), BEDO (2017b). Justification: Taxonomy. Cannot be confirmed through WoRMS Editorial Board (2019) or Ruhoff (1980). Family Chromodorididae Goniobranchus rufomaculatus (Pease, 1871). Reported as: Chromodoris histrio Bergh, 1878. Andaman Sea. Reported by: Jensen (2007), Nabhitabhata (2009). Justification: Taxonomy.

Gulf of Thailand, Andaman Sea. Reported by: Thamrongnawasawat et al. (2008), Nabhitabhata (2009). Justification: Geography. West coast of Africa (Bouchet, 1975). 191 The Marine and Estuarine Molluscs of Thailand Family Drilliidae Paradrillia serena (P. J. Fischer, 1927). Gulf of Thailand. Reported by: Gemert (2003). Justification: Fossil species (Leloux & Wesselingh, 2009). Family Epitoniidae Boreoscala blainei (Clench & R. D. Turner, 1953). Andaman Sea. Reported by: BEDO (2017b). Justification: Geography. Florida (Rosenberg et al., 2009). Family Eulimidae Sticteulima wareni Engl, 1997. Andaman Sea. Reported by: GBIF (2019c). Justification: Geography. Described from the Canary Islands in the Atlantic Ocean (Engl, 1997). Family Fasciolariidae Goniofusus spectrum (A. Adams & Reeve, 1848). Reported as: Fusinus spectrum (A. Adams & Reeve, 1848). Andaman Sea. Reported by: GBIF (2019a). Justification: Geography. Goniofusus spectrum is a Panamic species (Callomon & Snyder, 2008). The Thai species is possibly Fusinus stannum Callomon & Snyder, 2008. Latirus pulchellus (Reeve, 1847). Gulf of Thailand. Reported by: Gemert (2003). Justification: Taxonomy. Could not be verified through WoRMS Editorial Board (2019), but WoRMS Editorial Board (2019) lists the Mediterranean Fusinus pulchellus (Philippi, 1840). Family Ficidae Ficus subintermedia (d’Orbigny, 1852). No Thai locality provided. Reported by: THNHM. Justification: Fossil species (WoRMS Editorial Board (2018). Family Haliotidae Haliotis iris Gmelin, 1791. Andaman Sea. Reported by: Galli (2015). Justification: Geography. New Zealand (Spencer et al., 2009). Family Littorinidae Echinolittorina australis (Gray, 1826). Also reported as: Nodilittorina nodosa (Gray, 1839). Gulf of Thailand, Andaman Sea. Reported by: Nabhitabhata (2009), GBIF (2019a, 2019b). Justification: Geography. Endemic to Western Australia (Wilson, 1993; Reid, 2006). Echinolittorina feejeensis (Reeve, 1857). Gulf of Thailand, Andaman Sea. Reported by: Sanpanich et al. (2004), Sanpanich & Duangdee (2013). Justification: Geography. Tropical Pacific centred on Fiji (Reid, 2006). Echinolittorina miliaris (Quoy & Gaimard, 1833). Gulf of Thailand, Andaman Sea. Reported by: GBIF (2019b). Justification: Geography. Reid (2007) discusses the complex use of the name Echinolittorina miliaris but considers it to be endemic to Ascension Island in the Atlantic Ocean. Echinolittorina miliaris was not recorded by Sanpanich et al. (2004). Echinolittorina millegrana (Philippi, 1848). Reported as: Nodilittorina millegrana (Philippi, 1848). Andaman Sea. Reported by: Rosewater (1970), Tantanasiriwong (1978), Nateewathana et al. (1981), Bussarawit (1995), Subba Rao & Dey (2000), Nabhitabhata (2009), Kostina et al. (2016), BEDO (2017b), GBIF (2019a, 2019b). Justification: Taxonomy. Rosewater (1970) considered Echinolittorina reticulata to be a synonym of Echinolittorina millegrana, but Reid (2006) separated the two species, and restricted Echinolittorina millegrana to the northwestern Indian Ocean and Red Sea. The Thai records of Echinolittorina millegrana follow Rosewater (1970) and are probably all Echinolittorina reticulata. Echinolittorina trochoides (Gray, 1839). Gulf of Thailand, Andaman Sea. Reported by: KUMF, Swennen et al. (2001), Duangdee (2004), Sanpanich et al. (2004), Wells (2005), ONR & EPP (2006), Reid (2006), Kasetsart University (2007), Thamrongnawasawat et al. (2008), Nabhitabhata (2009). Justification: Taxonomy. Reid (2006) discusses the complex use of the name Echinolittorina trochoides (Gray, 1839) and considers it to probably be a synonym of Echinolittorina malaccana (Philippi, 1847). Littoraria filosa (G. B. Sowerby I, 1832). Reported as: Littorina filosa G. B. Sowerby I, 1832. Gulf of Thailand. Reported by: Morlet (1889). Justification: Geography. Reid (1986) shows the distribution of this species as northern Australia, southern Indonesia and southern New Guinea. Littoraria filosa was not recorded by Sanpanich et al. (2004). 192 F. E. Wells, K. Sanpanich, S. K. Tan & T. Duangdee Littoraria philippiana (Reeve, 1857). Gulf of Thailand. Reported by: Morlet (1889). Justification: Geography. Reid (1986) shows the distribution of this species as the east coast of northern Australia and southern New Guinea. Littoraria philippiana was not recorded by Sanpanich et al. (2004). Family Marginellidae Cryptospira glauca Jousseaume, 1875. Andaman Sea. Reported by: BEDO (2017b). Justification: Geography. Cryptospira glauca is restricted to the Bay of Bengal (northeast Sri Lanka and east coast of India). The Thai records are likely to be Cryptospira marchii (Wakefield, 2010). Rivomarginella morrisoni Brandt, 1968. Gulf of Thailand. Reported by: Galli (2015). Justification: WoRMS Editorial Board (2019) lists this as a freshwater species. Family Muricidae Ergalatax nodulosus (Pease, 1869). Andaman Sea. Reported by: Bussarawit (1991). Justification: Taxonomy. Could not be confirmed through WoRMS Editorial Board (2019).
