Taxonomy of the family Pareidae
Bibliography of the genus Asthenodipsas
Biodiversity of the family Pareidae








Genus
Asthenodipsas

Malayan Slug Eaters, Malayan Slug-eating Snakes

Malaiische Schneckennattern

Malayiske Sneglesnoge

1827 Amblycephalus Kuhl in Boie [not Amblycephalus Zedler 1803 (Cestoda)] (type species: Amblycephalus laevis Boie 1827; syn. Williams & Wallach 1989)
1864 Asthenodipsas Peters (type species: Asthenodipsas Malaccana Peters 1864)
1992 Internatus Rao & Yang (type species: Amblycephalus laevis Boie 1827; syn. Manthey & Grossmann 1997)
Contents: 8 species, of which 6 (75.0%) are endemic.
Remarks: Both laevis and malaccana were included in the genus Pareas for many years, until Rao & Yang (1992) placed them in a separate genus, which they named Internatus. However, Asthenodipsas, being an older name, has priority over Internatus, as pointed out by Ota (1999). More recently, vertebralis was also transferred to this genus (Grossmann & Tillack 2003).
Distribution: SE. Asia, Malay Archipelago.
Reported from: Brunei, Indonesia (Bangka, Java, Kalimantan, Natuna Islands [Bunguran], Siberut, Sumatra), Malaysia (Sabah, Sarawak, West Malaysia [incl. Seribuat Archipelago (incl. Tioman]), Singapore, Thailand.

Asthenodipsas tropidonotus

Sumatra Slug Eater

Sumatra-Schneckennatter

Sumatra-sneglesnog

1923 Amblycephalus tropidonotus Lidth de Jeude
Pareas tropidonotus Haas 1950
Internatus tropidonotus David & Vogel 1996
Asthenodipsas tropidonotus Iskandar & Colijn 2001

Remarks: Previously regarded as a synonym of vertebralis (e.g., Grossmann & Tillack 2003). Revalidated by Loredo, Wood, Quah, Anuar, Greer, Ahmad & Grismer (2013), although others (e.g., Haas 1950; David & Vogel 1996; Iskandar & Colijn 2001) had already regarded it as a valid species, but without discussion.

Bjerg-sneglesnog

1900 Amblycephalus vertebralis Boulenger
Pareas vertebralis Haas 1950

Distribution: Malaysia (West Malaysia [incl. Seribuat Archipelago (incl. Tioman)]).
