| Distribution | East Malaysia (Borneo: Sabah) Type locality: Mount Trusmadi, Tambunan, Sabah, East Malaysia (estimated: N 5.552776, E 116.516667, 2612 m a.s.l.). |
| Reproduction | |
| Types | Holotype. SP 04076, adult male, collected by Paul Yambun Imbun and other unspecified members of Sabah Parks on 14 May 1991. Paratypes. Juvenile male (ZRC 2.2742) collected by F.N. Chasen and H.M. Pendlebury in May 1929 from Marei Parei, Mount Kinabalu, Sabah, East Malaysia (estimated: N 6.080644, E 116.519022, 1668 m a.s.l.). |
| Diagnosis | Diagnosis: Morphological examination of the type series determined their placement in the genus Asthenodip- sas owing to their possession of smooth dorsal scales; absence of preoculars and suboculars; one or more supralabi- als in contact with the eye; a single anterior inframaxillary, followed by two or three pairs of inframaxillaries which are wider than long (Grossmann & Tillack 2003)—character states that diagnose Asthenodipsas from other genera of the family Pareidae. Asthenodipsas jamilinaisi sp. nov. can be differentiated from its congeners by the following combination of characters: a maximum SVL of 378 mm; 15/15/15 dorsal scale rows; 173–175 ventrals (males); 52–53 subcaudal scales (male); postoculars; 1–2(+0–1)+2 temporals; 6–7 supralabials, 3rd & 4th touching the eye; 5–6 infralabials, 3rd pair in contact; a sharp vertebral keel; dorsum of adults dark-brown with 44–48 indistinct dark bands that are more prominent on the lower dorsal rows along the flanks and extend onto the corners of the ventrals; chin & throat dark-brown; ventrals cream to light-yellow; and iris and pupils black (Tables 4–6; Fig. 4 & 5 in Quah et al. 2019). |
| Comment | Habitat: montane; only been found from 1500 to 2500 m a.s.l. in Sabah. Behavior: nocturnal |
| Etymology | The specific epithet jamilinaisi is a patronym in honour of Dr. Jamili Nais, the Director of Sabah Parks for his contributions to the research and conservation of biodiversity in the state and the first Malaysian to be appointed as a member of the World Heritage panel of the International Union for Conservation of Nature (IUCN). |
