ABSTRACT. We describe a new species of New Guinea vermivorous snake (Toxicocalamus) from a single specimen collected at Wangbin in the Star Mountains, Western Province, Papua New Guinea. The new species is the largest known member of the genus and can be differentiated from all other Toxicocalamus by a combination of the following characters: large size (total length of the holotype 1,200 mm), dorsal head scutes in the typical ‘‘colubrid-elapid dorsal nine-scute arrangement’’; separate, single preocular and paired postoculars; single anterior temporal and single or paired posterior temporals; six supralabials, with third and fourth supralabial contacting the orbit; dorsal scales in 15–15–15 rows; 203 ventral scales, 29 subcaudal scales; and a divided anal plate. Its erstwhile status, misidentified as Micropechis ikaheka in the collection of the Museum of Comparative Zoology, demonstrates the need for detailed examination of existing collections and is indicative of hidden diversity yet to be identified, not only in the field but also on the shelves of museum collections. We also provide a revised key to the genus Toxicocalamus. ABSTRAKSI. Kami mendeskripsikan spesies baru ular pemakan cacing (Toxicocalamus) di Papua New Guinea dari koleksi spesimen di Wangbin, Pegunungan Bintang, Propinsi bagian Barat, Papua Nugini. Spesies baru ini merupakan anggota genus dan dapat dibedakan dari semua ular pemakan cacing tanah (Toxicocalamus) lainnya dengan kombinasi dari berbagai ciri-ciri sebagai berikut: berukuran besar (panjang total holotype 1200 mm), sisik di kepala bagian atas bercirikan ‘‘colubrid-elapid sembilan sisik beraturan’’; terpisah, preocular tunggal and sepasang postocular; anterior temporal tunggal dan satu atau sepasang posterior temporal; enam supralabial, dengan supralabial ketiga dan keempat menghubungi orbit; sisik di bagian punggung berbaris 15–15–15; sisik di bagian perut berjumlah 203, sisik subcaudal berjumlah 29; dan piringan anal dibagi menjadi dua bagian. Status sebelumnya, salah diidentifikasi sebagai Micropechis ikaheka di koleksi Museum Comparative Zoology. Ini menunjukkan perlunya penyelidikan secara rinci terhadap hasil koleksi yang ada sekarang. Hal ini juga merupakan indikasi adanya keragaman tersembunyi yang belum teridentifikasi, tidak hanya di lapangan tapi juga di rak rak museum koleksi. Kami juga memberikan kunci revisi tentang spesies Toxicocalamus.

We trace the taxonomic history of Toxicocalamus, a poorly known genus of primarily vermivorous snakes found only in New Guinea and associated island archipelagos. With only a relatively limited number of specimens to examine, and the distribution of those specimens across many natural history collections, it has been a difficult task to assemble a complete taxonomic assessment of this group. As a consequence, research on these snakes has undergone a series of fits and starts, and we here present the first comprehensive chronology of the genus, beginning with its original description by George Albert Boulenger in 1896. We also describe a new species from the northern versant of the Owen Stanley Range, Oro Province, Papua New Guinea, and we present a series of comparisons that include heretofore underused characteristics, including those of unusual scale patterns, skull details, and tail tip morphology. Defined by the smallest holotype in the genus, the new species is easily differentiated from all other Toxicocalamus by a combination of the following eidonomic characters: fused prefrontal-internasal scute; single preocular, separate, not fused with prefrontal; minute circular, countersunk naris in the centre of a large, undivided, nasal scute; paired postoculars; single anterior temporal and paired posterior temporals; six supralabials, with 3rd and 4th supralabial contacting the orbit; dorsal scales in 15-15-15 rows; 235 ventral scales, 35 paired subcaudal scales; paired cloacal scales preceded by paired precloacal scales; and a short, laterally slightly compressed, 'Ultrocalamus-type' tail, terminating in a short conical scale. Differences from congeners in skull morphology include a reduced anterior extent of the parasphenoid, termination of the palatine tooth row at the anterior level of the parasphenoid, extent and shape of the premaxilla, shape and size of the prootics, extent and shape of the exoccipitals and occipital condyles, and features of the atlas-axis complex. This is the fifteenth species in the genus Toxicocalamus.
Zoosystematics and Evolution
A new species of New Guinea Worm-Eating Snake (Serpentes, Elapidae, Toxicocalamus Boulenger, 1896) from Western Highlands Province, Papua New GuineaWe describe a new species of New Guinea Worm-Eating Snake (Elapidae: Toxicocalamus) from a specimen in the reptile collection of the Papua New Guinea National Museum and Art Gallery. Toxicocalamus longhagensp. nov. can be easily distinguished from other species of this genus by the presence of paired subcaudals, a preocular scale unfused from the prefrontal scale, a prefrontal distinct from the internasal scale that contacts the supralabials, a single large posterior temporal and two postocular scales. The new taxon is currently known only from one specimen, which was collected from Mt. Hagen Town in Western Highlands Province, Papua New Guinea in 1967. The new species was originally identified as T. loriae, but the unique head scalation and postfrontal bone morphology revealed through micro-computed tomography scanning easily distinguish the new species from T. loriaesensu stricto. This is the first species of this genus described from Western Highlands Province.

Discovery of the second specimen of Toxicocalamus ernstmayri O’Shea et al., 2015 (Squamata: Elapidae), the first from Papua Province, Indonesia, with comments on the type locality of T. grandis (Boulenger, 1914)2020 •
Examination of historical specimens from western New Guinea in the Zoologische Staatssammlung Munich, Germany, led to the discovery of only the second specimen of the rarely encountered Star Mountains Worm-eating Snake, Toxicocalamus ernstmayri. This specimen is the first record of the species from the Indonesian part of New Guinea, extending its known range northwestward by 150 km. We also question the long-accepted collection locality for another poorly known species, T. grandis and document that it was most likely collected further up the Setekwa River at a higher elevation, in habitat more conducive to the ecology of a terrestrial to semi-fossorial genus and in keeping with the known mainland distribution of Toxicocalamus.

The Snakes Collection from Papua, Indonesia with Notes on Analysis of Stomach ContentA complete list of snake species found in Papua is essential for the conservation and management of these species in the future. This study provides a basic overview of the snake’s specimens deposited in the Laboratorium Zoology UNIPA (LZU) at Manokwari, West Papua Province during at last 15 years. In addition, these data are compared with specimens from the Muzeum Zoologicum Bogoriense (MZB) at Cibinong, West Java. We recorded 30 species of snakes from LZU (36.1%), and 43 species from MZB (51.8%), of the 83 species reported by Allison (2007). Clearly much more collecting effort needs to be focused on Papua, as less than 50% of the known species have voucher specimens in a museum. Of the species on collection, Morelia viridis is the only protected species on Papua, while Lycodon aulicus is the only alien species. We also conducted a through investigation of prey content for each species using preserved stomach contents. We dissected a total of 93 specimens. Twenty-nine percent of th...

An Annotated Checklist of the Herpetofauna of Beris Valley, Kedah, Malaysia2011 •
The herpetofauna of Beris Valley, Kedah, Malaysia, was studied using a rapid assessment survey during a scientific expedition organised by the School of Biological Sciences at the Universiti Sains Malaysia, from 14–17 August 2009. All amphibians and reptiles were observed and captured during the four-day survey along the ditches, roads, dam areas, swamps, forest trails and streams. The results showed that 14 species of amphibians from 9 genera and 5 families inhabit the area, and 7 species of lizards, 5 species of snakes and 2 species of freshwater turtles were also present in the area. Fejervarya limnocharis and Microhyla butleri seemed to be the most common amphibians, while Hemidactylus frenatus and Varanus salvator were the most common reptiles in the area. This report constitutes a preliminary checklist and first record of amphibians and reptiles in Beris Valley, Kedah. The number of specimens was less than expected because of the very short survey period, but we hope to record more species in future studies.Suatu kajian tentang herpetofauna telah dilakukan secara penilaian pantas di Lembah Beris, Kedah, Malaysia semasa ekspedisi saintifik yang dianjurkan oleh Pusat Pengajian Sains Kajihayat, Universiti Sains Malaysia bermula pada 14–17 Ogos 2009. Selama empat hari, kesemua amfibia dan reptilia telah ditinjau dan ditangkap disekitar parit, jalan raya, kawasan empangan, paya, denai hutan dan sungai. Keputusan menunjukkan sebanyak 14 spesies amfibia daripada 9 genus dan 5 famili mendiami kawasan tersebut. Di samping itu sebanyak tujuh spesies cicak, lima spesies ular dan dua spesies kura-kura air tawar turut mendiami kawasan tersebut. Dua spesies amfibia iaitu Fejervarya limnocharis dan Microhyla butleri dan dua spesies reptilia iaitu Hemidactylus frenatus dan Varanus salvator merupakan spesies amfibia dan reptilia yang biasa dan kerap ditemui di kawasan ini. Laporan ini adalah senarai awal dan merupakan laporan pertama tentang kepelbagaian amfibia dan reptilia di Lembah Beris, Kedah. Jumlah spesimen yang diperolehi daripada kajian ini adalah lebih rendah daripada jangkaan kerana tempoh kajian yang amat singkat dan diharapkan lebih banyak spesimen dapat direkodkan pada masa yang akan datang.
