Annotated checklist of the rotifers (Phylum Rotifera), with notes on nomenclature, taxonomy and distribution

Hendrik Segers

The muddled taxonomy of the Cephalodella crassipes complex is reviewed and changes in synonymy are proposed. Four species, viz. C. crassipes (LORD), C. xenica MYERS, C. eupoda MYERS, and C. jakubskii WISZNIEWSKI are considered to be valid morphospecies. Cephalodella donneri HAUER is synonymized with C. jakubskii. Cephalodella harringi SMIRNOV is rejected as a possible synonym of C. crassipes. The ecology and biogeography of all valid species is summarized.

Rotifers have attracted the attention of biologists for well over 200 years. Interest in these exquisite animals rests in their diverse morphology, short generation time resulting in high growth rates, ability to withstand desiccation, and wide distribution, coupled with evidence of cryptic speciation. Moreover, three modes of reproduction are present in the phylum: obligatory sexuality, cyclical parthenogenesis, and obligatory ameiotic parthenogenesis. Thus, this phylum offers a rich field of study. Recognizing the need to share advances in knowledge, a triennial meeting, the International Rotifer Symposium (IRS), was begun in 1976. The most recent symposium (13(th) IRS) was held at Shillong (India) from 18-24, November 2012. In this commentary we considered the development of rotifer research as viewed through the lens of more than 35 years of IRS. Initially papers presented at the IRS focused on ecology, morphology, and pure taxonomic problems, with little applied work being repo...

Rotifers are bilateral symmetric animals belonging to Protostomia. The ultrastructure of the rotiferan trophi suggests that they belong to the Gnathifera, and ultrastructural similarities between the integuments and spermatozoa as well as molecular evidence strongly suggest that rotifers and the parasitic acanthocephalans are closely related and form the clade Syndermata. Here we discuss the phylogenetic position of rotifers with regard to the gnathiferan groups. Originally, Gnathifera only included the hermaphroditic Gnathostomulida and the Syndermata. The synapomorphy supporting Gnathifera is the presence of pharyngeal hard parts such as jaws and trophi with similar ultrastructure. The newly discovered Micrognathozoa possesses such jaws and is a strong candidate for inclusion in Gnathifera because their cellular integument also has an apical intracytoplasmic lamina as in Syndermata. But Gnathifera might include other taxa. Potential candidates include the commensalistic Myzostomida and Cycliophora. Traditionally, Myzostomida has been included in the annelids but recent studies regard them either as sister group to the Acanthocephala or Cycliophora. Whether Cycliophora belongs to Gnathifera is still uncertain. Some analyses based on molecular data or total evidence point towards a close relationship between Cycliophora and Syndermata. Other cladistic studies using molecular data, morphological characters or total evidence suggest a sister group relationship between Cycliophora and Entoprocta. More molecular and morphological data and an improved sampling of taxa are obviously needed to elucidate the phylogenetic position of the rotifers and identify which phyla belong to Gnathifera.

Here I present an annotated checklist of the taxon, giving the global distribution of the valid species. This checklist contains over 3,000 available names at the genus- and species-group level, including valid names and a non-comprehensive list of synonyms. A number of taxonomic and nomenclatural suggestions following from the review is presented. Suggestions include several new synonyms and two nomina nova: Dissotrocha kostei for Dissotrocha aculeata Koste, 1996 non Ehrenberg, 1838 (stat. nov., ex. Dissotrocha hertzogi aculeata) and Lepadella zigzag for Lepadella bractea Myers, 1934 non (Ehrenberg, 1838). This contribution also describes features of an on-line, global names database of the Rotifera, on which this checklist is based. Key words: biodiversity, biogeography, Rotifera Introduction In recent years science has witnessed a rapid evolution from print to electronic media in the production of taxonomic resources. This inevitable evolution (see Godfray, 2002) is fostered by a large number of initiatives like the Global Biodiversity Information Facility (GBIF, http://www.gbif.org/), the Integrated Taxonomic Information System (ITIS, http://www.itis.usda.gov/), Species2000 (http://www.sp2000.org), and Universal Biological Indexer and Organizer (uBIO: http://www.ubio.org), to name a few. Even long-established resources like the International Commission on Zoological Nomenclature (ICZN, 1999; see http:// www.iczn.org/) are turning towards the World Wide Web, (e.g., with the ZooBank initiative: http:// www.zoobank.org/; Polaszek, 2005) notwithstanding the obvious difficulty the ephemeral character of electronic media pose to a stable scientific nomenclature. Accepted by R. Dalgleish: 26 Apr. 2007; published: 31 Aug. 2007 3 Acknowledging this development, I present a checklist of the Rotifera of the world, extracted from a database compiled in the framework of the project `Freshwater Animal Diversity Assessment' (see http:// FADA.biodiversity.be). In addition to the checklist I provide a short overview of a number of features of the database and some taxonomic and nomenclatural changes resulting from the literature review required to prepare the list. The present paper, together with the analysis of the diversity and biogeography of the Rotifera (Segers, in press), are intended as citable source for the database. Approach The checklist is based on the taxonomy of rotifers as presented in monographs listed in Table 1, and numerous recent publications. For practical reasons, only names or taxonomic changes published before November 1, 2006 are included. Considering that subsequent lumping of distributional data is easy whereas the inverse is not, a splitting rather than lumping approach to taxonomy has been adopted. As a consequence, the diversity of rotifers turns out to be higher than previous estimates. This is especially so for genera like Lepadella and Lecane. In Lepadella, the lack of any comprehensive revision is responsible for the discrepancy, while Lecane is exemplary of the tendency towards a less inclusive species concept in Rotifera during recent years. This approach has been corroborated by recent research using molecular (e.g., Goméz et al., 2002) or detailed morphological techniques (Giri & José de Paggi, 2006), or combining different approaches (Ricci, 2001) and biogeography (Segers & Shiel, 2003), showing that diversity has generally been underestimated in Rotifera. On the other hand, many rotifer taxa exhibit wide morphological variability, either as a result of phenotypic plasticity and/ or distortion during fixation or dehydration. Although this has long been known and is well documented (see Dumont, 1983; Koste & Shiel, 1989c; Segers, 1998), variants are still frequently being described as subspecies of common species. Such taxa, together with insufficiently described ones, are included in the present checklist as their names are available, but are tagged species inquirenda in the absence of a critical taxonomic revision. Names listed as referring to unrecognizable taxa in recent revisions listed in Table 1 have not been included. The taxonomy reflected in the list may not be satisfactory, especially in taxa for which no recent comprehensive reviews are available (e.g., Brachionidae, Lepadellidae, and Notommatidae). The treatment of synonyms in the database is not comprehensive, but focuses on synonyms that occur in recent literature or that are occasionally listed as valid taxa. Older synonyms (especially in the morphologically variable Brachionidae: Brachionus and Keratella) can be found in Harring (1913) and Wiszniewski (1954). When necessary, care was taken to correct names in accordance with the International Code of Zoological Nomenclature (ICZN, 1999). Incorrect subsequent spellings are generally not taken into account unless they have some nomenclatural significance beyond their mere existence: keeping track of published spelling variants and nomina nuda in the vast ecological literature on rotifers is a daunting task with dubious relevance. Data on distribution are presented for taxa considered valid only. This information is mostly drawn from the literature as in Table 1 and, as much as feasible, included only after critical assessment. A more complete analysis of the biodiversity and distribution of the rotifers, based on the data presented here, is as in Segers (in press). Scope The checklist and database, in its present version, contain 2127 species-level taxa of Rotifera, of which 109 are presently considered species inquirenda, and some 800 synonymous or alternative genus- and species- 4 · Zootaxa 1564 © 2007 Magnolia Press SEGERS level names. The vast majority of the valid names belong to Monogononta (1566), whereas Bdelloidea (461) and, especially, Seisonida (3) are much less diverse. The following information is provided: Valid names of genus- and species-level taxa with authority, and the original combination of species-level names. Genera and species within genera are arranged alphabetically in the checklist in order to facilitate information retrieval. This ordering is consistent with Harring (1913) and Wiszniewski (1954). Names with authority of synonyms of available genus-and species-level names, the latter in their original combination. The synonymy is incomplete for taxa in which a high number of older synonyms exist. For these I refer to Harring (1913) and Wiszniewski (1954). Names with authority of some species inquirendae not included in recent revisions (see Table 1). Taxonomic comments. This includes indication of taxonomically problematic cases, or instances where synonyms are in use as names of infrasubspecific variants. Unavailable names of infrasubspecific taxa are added in comments, except for those in genera like Brachionus and Keratella, where citing the exceedingly high number of names of variants, forms etc. would only add to confusion. Occurrence in eight large biogeographical regions (Palearctic, Afrotropical, Oriental, Nearctic, Neotropical, Australian, Pacific and Antarctic), as circumscribed in Martens et al. (in press; see Figure 1), for all valid and recognisable species-level fresh- and/or brackishwater taxa. Marine, parasitic and interstitial taxa are mentioned as such. If relevant, a comment on distribution is added, mostly indicating that a regional record of a species is dubious, or that such a record may result from species introduction. FIGURE 1. Definition of the eight regions used in this work (after Martens et al., in press.) In addition, the database includes a higher-level classification of the free-living rotifers, after Segers (2002) and Wallace et al. (2006). The Acanthocephala, of which several authors argue that they are highly adapted parasitic representatives of the group (Mark Welch, 2000; see also Garcia-Varela et al., 2000; Giribet et al., 2000), are excluded. ANNOTATED CHECKLIST OF THE ROTIFERS Zootaxa 1564 © 2007 Magnolia Press · 5 The goal of the databasing exercise was not to introduce taxonomic or nomenclature novelties. However, a number of instances was found in which a change in taxonomy appeared warranted. In addition, some actual or potential homonyms were found. Many of the latter concern cases of congeneric, but not conspecific, subspecies with identical subspecies names. Because of the principle of coordination in zoological nomenclature, such cases are better avoided, or at least monitored. Especially, the subspecies rank of many rotifer subspecies is exclusively based on the consideration that there is a morphological resemblance between taxa. We now know that cryptic speciation occurs, and may be common, in Rotifera; hence such arguments for attributing subspecific rank are losing what little ground they ever had. Moreover, there are indications that what were once thought to be mere infrasubspecific variants could be taxonomically relevant entities (e.g., Giri & José de Paggi, 2006). Here, replacement names are only suggested for those junior homonyms that denote valid taxa. Other cases are listed as caution against potential future confusion. The following are some suggestions on taxonomy and nomenclature: Anchitestudinella mekongensis B‘rziÃÓ, 1973 B‘rziÃÓ (1973) contains two alternative spellings for the single species of Anchitestudinella: mekogensis and mekongensis. Subsequent authors have used either spelling, but none has ever clarified which of the two should be considered the correct spelling. Considering the etymology of the name, which is derived from River Mekong, I suggest treating the latter, with -n-, as correct original spelling under Art. 24.2.3 of the ICZN. Brachionus inermispinosus De Smet, 1989 = Epiphanes brachionus spinosa Rousselet, 1901 (new synonym). The detailed description and, especially, figures of the habitus and trophi of B. inermispinosus by De Smet (1989) reveal that the animal does not belong in Brachionus; rather, it is an Epiphanes and, most likely, synonymous with E. brachionus spinosa. Brachionus anchorporus Xu, Chen & Rao, 1997 = B. durgae Dhanapathi, 1974 (new synonym). The description by Xu et al. (1997) undoubtedly depicts B. durgae, a taxon of which these authors were apparently unaware. Brachionus angularis orientalis Sudzuki, 1989 = B. angularis Gosse, 1851 The name B. angularis orientalis is a potential junior homonym of B. orientalis Rodewald, 1937, if the name would ever be used at the species level. Sudzuki’s (1989) species, however, is based on a relatively common variant of B. angularis and is treated as a synonym rather than a different subspecies. This is in agreement with Sudzuki’s (1998) treatment of the taxon as of infrasubspecific rank, although he reverts to listing it as a subspecies in Sudzuki (1999). Brachionus angularis pseudokeikoa Sudzuki, 1992; B. angularis pyriformis Sudzuki & Huang, 1997; B. angularis donghuensis Sudzuki & Huang, 1997; B. morondavaensis Sudzuki, 1998 = B. angularis Gosse, 1851 (new synonyms) Sudzuki (1999) cites the three subspecies listed above as species, in which case Sudzuki & Huang’s (1997) B. pyriformis would have to be treated as a junior homonym of B. pyriformis Barrois & Daday, 1894, an established junior synonym of B. angularis. All four fall within the range of variability of B. angularis; B. angularis donghuensis is a poorly contracted specimen of B. angularis bidens, according to a photograph in Sudzuki (1999). A fifth taxon, B. angularis daitojimensis Sudzuki, 1992 is listed as an infrasubspecific variant, hence a synonym, of B. angularis by Sudzuki (1999) himself. 6 · Zootaxa 1564 © 2007 Magnolia Press SEGERS B. dimidiatus isigakiensis Sudzuki, 1992; B. cluniorbicularis isigakiensis Sudzuki 1992 and B. durgae isigakiensis Sudzuki 1992 Sudzuki (1992) named three new Brachionus subspecies “isigakiensis”. All three are easily recognized as belonging to previously established taxa, as far as can be judged from the relevant descriptions and photographs in Sudzuki (1992, 1999): B. dimidiatus isigakiensis Sudzuki, 1992 (Brachionus isigakiensis in Sudzuki 1998, 1999) is a poorly contracted B. bennini Leissling (new synonym). B. cluniorbicularis isigakiensis Sudzuki 1992 is an unspined variant (f. cluniorbicularis) of B. quadridentatus Hermann (new synonym). B. durgae isigakiensis Sudzuki 1992 falls within the range of variability of the nominal species, hence it is here considered a synonym of B. durgae Dhanapathi (new synonym). As all three enter into synonymy, there appears to be no imminent danger of nomenclatural confusion between the three potential homonyms. Brachionus brevispinus Sudzuki & Huang, 1997 = B. huangi Zhuge & Koste, 1996 (new synonym). Although the taxonomic separation of the short-spined B. huangi and B. brevispinus versus B. diversicornis Daday may require substantiation, B. huangi and B. brevispinus are obviously identical. As B. brevispinus Sudzuki & Huang, 1997 enters into synonymy, there is no danger of confusion with its senior homonym B. brevispinus Ehrenberg, 1832, itself a synonym, and representing a well-known and common infrasubspecific variant, of B. quadridentatus Hermann. Brachionus lyratus yonaguniensis Sudzuki, 1992 = B. angularis Gosse, 1851 (new synonym). This taxon, listed as B. yonaguniensis by Sudzuki (1999), appears to be yet another variant of B. angularis. An appurtenance to B. lyratus is not evident from the available description and photographs. Brachionus variabilis kasumigaurensis Sudzuki, 1998 = B. rubens Ehrenberg, 1838 (new synonym). The available pictures of B. variabilis kasumigaurensis (see Sudzuki, 1999), especially the shape of antero-dorsal spines and minute size of the rounded process on the dorsal foot aperture margin reveal a synonymy with B. rubens. Encentrum grande (Western, 1891) and Encentrum kulmatyckii (Wiszniewski, 1953) De Smet in De Smet & Pourriot (1997) argued that the description of Encentrum grande (Western) is unrecognisable, and proposed to refer to Harring & Myers’ (1928) description as reference for the taxonomic identity of E. grande. Considering the poor quality of many original descriptions of Rotifera and the absence of type material, this is common practice in rotifer taxonomy. However, he further retained E. grande (Western) as species inquirenda, and included a E. grande Harring & Myers, 1928 in his treatment. This confusingly results in the recognition of two homonymous taxa, one E. grande (Western) and E. grande sensu Harring & Myers (1928) which, in fact, should be attributed to De Smet (1997). The name Encentrum kulmatyckii (Wiszniewski, 1953), a junior synonym of E. grande sensu Harring & Myers (1926), is available for the latter taxon. ANNOTATED CHECKLIST OF THE ROTIFERS Zootaxa 1564 © 2007 Magnolia Press · 7 Dissotrocha hertzogi aculeata Koste, 1996 versus Dissotrocha aculeata aculeata Ehrenberg, 1838 Koste’s (1996) taxon has distinct body outgrowths (none in D. hertzogi), and lacks the extraordinarily long rostrum ciliae and offset spur tips of Dissotrocha hertzogi (see Donner, 1965). These morphological differences are of a nature and magnitude that is generally considered relevant at the species level in bdelloid rotifer taxonomy. In addition, it is particularly difficult to conform a species, let alone a subspecies, definition to an exclusive parthenogenetically reproducing taxon. I therefore suggest treating the two as separate species-level taxa and, because of the homonymy of Koste’s name with Ehrenberg’s, I have the pleasure to suggest the name Dissotrocha kostei, honouring Dr h.c. W. Koste, as replacement name for the taxon (nomen novum). Keratella heywoodi Dartnall, 2005 = K. kostei Paggi, 1981 (new synonym) Both Dartnall’s (2005) and Paggi’s (1981) descriptions point to the absence of a foundation pattern on the dorsal lorica, small size of antero-median and antero-intermedian, but large and ventrally-pointed anterolateral spines as characteristic features of their new species. As Dartnall (2005) does not mention K. kostei in his text, he may not have been aware of the existence of that name. The species occurs in Patagonia, Argentina (Paggi, 1981), and on the Falkland Islands and South Georgia (Dartnall, 2005). Pompholyx acutangula Wu, 1981 = Testudinella brevicaudata Yamamoto, 1951 (new synonym). Wu’s (1981) clear and detailed illustrations depict an animal with a large foot aperture. It therefore does not belong to Pompholyx, rather it is a previously described Testudinella, T. brevicaudata. Testudinella tridentata obtusa Wu, 1981 = Testudinella greeni Koste, 1981 (new synonym). The figures and photographs of Wu’s T. tridentata obtusa unmistakably depict a T. greeni. Apparently, Wu (1981) was not aware of the latter species. Hemimonostyla blachei tutiurensis Sudzuki, 1998 = Lecane stenroosi Meissner, 1908 (new synonym). The photograph of H. blachei tutiurensis by Sudzuki (1998) leaves no doubt as to its synonymy with L. stenroosi. Lecane kasumiensis Sudzuki, 1998 = Lecane papuana (Murray, 1913) (new synonym). Again, the photograph of L. kasumiensis by Sudzuki (1998) leaves no doubt as to its synonymy with L. papuana. Lepadella bractea Myers, 1934 versus Squamella bractea Ehrenberg, 1838. Myers’ name is threatened by its homonymy with Squamella bractea Ehrenberg, an established junior synonym of Lepadella patella Müller, 1786. Here, a replacement name is in order as confusion between the two has occurred (Nogrady in Boyko, 1994), notwithstanding that Ehrenberg’s name is hardly ever found in combination with the genus name Lepadella. Myers’ (1934) animal is a remarkable but rare Northeast North American endemic that is unmistakable by the prominent zig-zag crest on its dorsal lorica. I suggest the name Lepadella zigzag as nomen novum for the taxon. 8 · Zootaxa 1564 © 2007 Magnolia Press SEGERS Lepadella parvula De Graaf, 1956 versus L. parvula Bryce, 1893 Lepadella parvula De Graaf, 1956 is a junior homonym of Lepadella parvula Bryce, 1893 and of the previously replaced L. parvula Montet, 1915 (valid name: Lepadella minuta Weber & Montet, 1919). As Lepadella parvula De Graaf is an established junior synonym of Lepadella patella Müller, there is no imminent need for a replacement name. Macrotrachela ligulata Haigh, 1965; Macrotrachela nana ligulata Schulte, 1954; Macrotrachela quadricornifera ligulata B‘rziÃÓ, 1950 Awaiting a revision of the large and complex genus Macrotrachela, I merely point out that Macrotrachela quadricornifera ligulata B‘rziÃÓ, 1950 and M. nana ligulata Schulte, 1954 are potential senior homonyms of M. ligulata Haigh, 1965, if any or both of the first-mentioned ones would ever be raised to species rank. The genus Diplois Gosse, and its single species D. daviesae Gosse are here considered genus et species inquirendae. Scrutiny of the available literature on the taxon, and consultation with colleagues revealed that only Gosse’s description exists, and that there are no reliable records or sightings of the species (W.H. De Smet, in lit., R.J. Shiel, in lit., C. Jersabek, in lit.). The description of Pseudoembata parasitica by Wycliffe & Michael (1968) does not enable recognition of the taxon; the arguments for erection of a new genus are not supported in the literature (see Donner, 1965). Also this taxon is therefore considered genus et species inquirendae. Future prospects The database mentioned here will be made freely accessible through the World Wide Web. In a first phase, researchers will be offered the possibility to select and extract a structured name list from the database. By this service, it is hoped to reduce the number of misspellings and other inconsistencies in the published literature. In a second phase, the possibility will be offered to submit and save regional or local (georeferenced) checklists to the database, together with metadata on these checklists. One of the goals of the database is to provide a resource to as reliable as possible data on the distribution of Rotifera. Hence, we envisage installing a system comparing submitted lists with reviewed distributional data so that new regional species records will be highlighted and, eventually, reviewed by peers. This review process may involve submitting material enabling the positive identification of the species concerned and, if this is possible by the nature of the taxon, by illustrating remarkable records through relevant photographs or original drawings on the web site.

The exact taxonomic identity of the latter can’t be inferred from the original description; however, it is clear that the two are not conspecific (Harring, 1913). I therefore follow Harring (1913) rather than Donner (1965), who lists Vorticella marcoura as synonym of Rotaria macrura (Schrank). 90 · Zootaxa 1564 © 2007 Magnolia Press SEGERS Callidina sordida Western, 1893 Rotaria sordida fimbriata (Murray, 1906): AFR, AUS, ORI, PAC, PAL Rotifer longirostris fimbriatus Murray, 1906 Rotaria sordida sordida (Western, 1893): AFR, AUS, NEA, NEO, ORI, PAL Syn.: Callidina longirostris Janson, 1893 Rotaria spicata (Murray, 1902): NEA, PAL Rotifer spicatus Murray, 1902 Rotaria tardigrada (Ehrenberg, 1830): AFR, AUS, NEA, NEO, ORI, PAL Rotifer tardigradus Ehrenberg, 1830 Syn.: Rotifer maximus Bartsch, 1870 Syn.: Rotifer tardus Ehrenberg, 1838 Rotaria tridens (Montet, 1915): AUS, NEA, NEO, PAL Rotifer tridens Montet, 1915 Syn.: Rotaria tridentata Varga, 1954 Rotaria trisecata (Weber, 1888): NEA, NEO, PAL Rotifer trisecatus Weber, 1888 Rousseletia Harring, 1913 Rousseletia corniculata Harring, 1913: NEA Scaridium Ehrenberg, 1830 Scaridium bostjani Daems & Dumont, 1974: AFR, AUS, NEA, NEO, ORI, PAL Scaridium elegans Segers & De Meester, 1994: AFR, AUS, NEO, ORI (record from China by Zhuge (1997) is S. longicaudum) Scaridium elongatum Segers, 1996: NEO Scaridium grande Segers, 1995: AFR, ORI Scaridium longicaudum (Müller, 1786): AFR, ANT, AUS, NEA, NEO, ORI, PAC, PAL Trichoda longicauda Müller, 1786 Scaridium montanum Segers, 1995: PAL Scaridium neglectum Segers, 1997: NEA Scepanotrocha Bryce, 1910 Scepanotrocha corniculata Bryce, 1910: AUS, NEO, PAL Scepanotrocha delicata Donner, 1949: AUS, PAL Scepanotrocha galeata Milne, 1916: AFR, PAL Scepanotrocha haueri Donner, 1962 Scepanotrocha haueri amota Donner, 1962: PAL Scepanotrocha haueri haueri Donner, 1962: PAL Scepanotrocha impexa Donner, 1962: PAL Scepanotrocha parva Schulte, 1954: PAL Scepanotrocha rubra Bryce, 1910: AUS, NEA, NEO, PAL Scepanotrocha semitecta Donner, 1951: NEO, PAL Scepanotrocha setifera Haigh, 1963: AUS Scepanotrocha simplex De Koning, 1947: AUS, NEO, PAL ANNOTATED CHECKLIST OF THE ROTIFERS Zootaxa 1564 © 2007 Magnolia Press · 91 Seison Grube, 1861 Seison africanus Sørensen, Segers & Funch, 2005 Seison nebaliae Grube, 1861 (marine, epizoic on Nebalia) Syn.: Seison grubei Claus, 1876 Syn.: Saccobdella nebaliae Van Beneden & Hesse non Grube, 1864 Sinantherina Bory de St. Vincent, 1826 Sinantherina ariprepres Edmondson, 1939: AUS, NEA, NEO Sinantherina procera (Thorpe, 1893): NEO, ORI Megalotrocha procera Thorpe, 1893 Sinantherina semibullata (Thorpe, 1893): AFR, AUS, NEA, NEO, ORI, PAL Megalotrocha semibullata Thorpe, 1893 Syn.: Megalotrocha binotata Daday, 1897 Sinantherina socialis (Linnaeus, 1758): AFR, AUS, NEA, NEO, ORI, PAL Hydra socialis Linnaeus, 1758 Syn.: Megalotrocha alboflavicans Ehrenberg, 1838 Sinantherina spinosa (Thorpe, 1893): AFR, AUS, NEA, NEO, ORI, PAL Megalotrocha spinosa Thorpe, 1893 Sinantherina triglandularis Arora, 1963 (species inquirenda) Sphyrias Harring, 1913 Sphyrias lofuana (Rousselet, 1910): AFR, PAC Notops lofuana Rousselet, 1910 Squatinella Bory de St. Vincent, 1826 Stephanops Ehrenberg, 1830 Listrion Schmarda, 1846 Squatinella bifurca (Bolton, 1884): PAL (includes the infrasubspecific variant gigantea Pourriot, 1971) Stephanops bifurcus Bolton, 1884 Squatinella geleii Varga, 1933: PAL Squatinella lamellaris (Müller, 1786): AFR, AUS, NEA, NEO, ORI, PAC, PAL Brachionus lamellaris Müller, 1786 Syn.: Squatinella aurita Wulfert, 1950 (incl. the infrasubspecific variant myersi Voigt, 1957) Syn.: Stephanops dichthapsis Anderson, 1889 Syn.: Squatinella donneri Wulfert, 1956 Syn.: Stephanops emarginatus Bilfinger, 1894 Syn.: Stephanops groenlandicus Bergendal, 1892 Syn.: Stephanops intermedius Burn, 1889 Syn.: Squatinella minor Wulfert, 1961 Syn.: Stephanops muticus Ehrenberg, 1832 (synonym considered an infrasubspecific variant (f. mutica) of S. lamellaris) Syn.: Stephanops tridentatus Fresenius, 1858 (synonym considered an infrasubspecific variant (f. tridentata) 92 · Zootaxa 1564 © 2007 Magnolia Press SEGERS of S. lamellaris) Squatinella leydigii (Zacharias, 1886): AUS, NEA, NEO, PAL (incl. the infrasubspecific variant longiseta Pourriot, 1971) Stephanops leydigii Zacharias, 1886 Syn.: Squatinella longispinata auct.
