Distribution	India (Western Ghats, Kerala, Tamil Nadu ?), elelvation 1980 m to 2300 m Type locality: “Indes-Orientales” [= East Indies, including India].
Reproduction	ovovivparous
Types	Syntypes: MNHN-RA 1208, longest syntype 500 mm (G.S. Perrotet, 1822–1832), 5 specimens, location of other syntypes unknown. Holotype: BMNH 1946.1.9.80-81 [tropidococcyx]
Diagnosis	Diagnosis: It is morphologically separated from most other Indian species by the absence of rostral appendage (vs. present in all Indian congeners except A. dispar, A. travancorica sp. nov.). It differes from the latter species by a lower number (65–86) of subcaudal shields (vs. 103–125 in A. dispar and 130 in Ahaetulla travancorica sp. nov.) and complete absence of loreal scales on either side of the head (vs. 0–1 loreals in A. dispar and 2 in Ahaetulla travancorica sp. nov.) (Fig. 24, Mallik et al. 2020). Additional details (848 characters) are available for collaborators and contributors. Please contact us for details.
Comment	Mildly venomous but usually harmless for humans. Synonymy: partly after Mallik et al. 2020. Distribution: Reports from Myanmar are probably erroneous (MCDOWELL & JENNER 1988). See map in Mallik et al. 2020: 14 (Fig. 4). Habitat: In contrast to most other members of the genus, A. perroteti is predominantly terrestrial to semi-arboreal, inhabiting the montane grasslands and the shola forest mosaic of the Upper Nilgiris (Mallik et al. 2020), even though Harrington et al. 2018 classified it as fully arboreal.
Etymology	Named after George Samuel Perrottet (1790–1870) a French botanist, who also worked on the natural history of Indian biota.
