Diagnosis | Diagnosis: This is a species of usually grey-brown coloured Ahaetulla having an elongate multi-scaled rostral appendage and a rhomboid crown marking (vs. rostral scale not multi-scaled in all other Peninsular India Ahaetulla spp., except A. anomala and A. sahyadrensis nom. nov.); lacking white or yellow ventrolateral stripe (vs. present in all regional congeners except A. sahyadrensis nom. nov.); 8 pre-diastemal and 7 post-diastemal maxillary teeth (vs. 7 and 9 in A. isabellina comb. nov., 6 and 7 in A. malabarica sp. nov., vs. 6 and 11 in A. farnsworthi sp. nov., vs. 6 and 8 in A. borealis sp. nov., vs. 7 and 7 in A. oxyrhyncha comb. nov. & 7 and 6 in A. sahyadrensis nom. nov. from India, dissected from BNHS 2010); differs from A. sahyadrensis nom. nov. of India in ventral scale counts 179–193 [182–186 in BNHS specimens] (vs. 182–203 [186–202 in our study] in A. sahyadrensis nom. nov.) and subcaudal scale counts 151–178 [158–159 in BNHS specimens] (vs. 169–208 [175–208 in our study] in A. sahyadrensis nom. nov.); lower posterior dorsal scale rows count 10–11 (vs. 12–13 in A. sahyadrensis nom. nov.)

Comment | Synonymy: partly after WALLACH et al. 2014: 21, Mallik et la. 2020). Diet: lizards and other vertebrates Distribution: see map in Deepak e al. 2019: 499 (Fig. 1) and Mallik et al. 2020: 14 (Fig. 4). Reports from Gujarat are probably misidentifications of A. pulverulenta (Vyas, 1988, Patel & Vyas 2019). Mallik et al. 2020 restricted pulverulenta to Sri Lanka and assigned populations from S India to A. sahyadrensis, a similar and closely related species. Habitat: fully arboreal (Harrington et al. 2018). |
Etymology | From Latin, named after its ‘ashy’ or ‘dusty’ greyish brown colouration. |
