Type locality: “America” (fide LINNAEUS 1758; in error)
|Types||Holotype: NRM 81|
|Diagnosis||Diagnosis and definition (Ahaetuliinae): Snakes of this subfamily are arboreal and are diagnosed by keeled ventral and subcaudal scales (laterally notched in some species), and enlarged posterior grooved fangs lacking in some Dendrelaphis. Support for monophyly of this clade is very strong (SHL = 100) as also reported in Pyron et al. Ahaetuliinae is further split into two monophyletic groups: 1) Dryophiops and Ahaetulla (SHL = 96) and; 2) Chrysopelea and Dendrelaphis (SHL = 100). Diagnostic characteristics of the first group include, elongate and laterally-compressed bodies, elongate heads, 15 smooth mid-body dorsal scale rows, and large eyes with horizontal pupils and well-developed canthus rostralis outfitting these snakes with binocular vision . Features diagnostic of the second group include, slender body, rectangular slightly compressed heads, large eyes with round pupils, 13–17 smooth to weakly-keeled mid-body dorsal scale rows. Chrysopelea are celebrated for their unique gliding behavior, whereas Dendrelaphis are capable of jumping [FIGUEROA et al. 2016, SOCHA 2011].|
For a table of diagnostic characters comparing the 4 genera of Ahaetuliinae see Mallik et al. 2019: 10 (Table 3).
|Comment||Synonymy: Ahaetulla GRAY 1825 was proposed to be listed as a rejected and invalid name by Savage & Oliver 1957 as it is a junior homonym of Ahaetulla LINK 1807.|
Mildly venomous but usually harmless for humans.
Habitat: fully arboreal (Harrington et al. 2018).
|Etymology||Named after Greek “mucterizo” = I turn up the nose. Removed from the list of Pulau Tioman by ROOIJEN & ROOIJEN 2002.|
The genus names is derived from the Sri Lankan language Sinhala, ahaetulla/ahata gulla/as gulla, meaning “eye plucker” or “eye picker” for belief that they pluck out the eyes of humans as accounted by the Portuguese traveler João Ribeiro in 1685. The gender is feminine.
