| Distribution | India (S Karnataka) Type locality: Paralai, near Valparai (10.335 N, 76.952 E, 1100 msl; original type locality); neotype locality: Oru Komban hills (10.4077 N, 76.7177 E, 1077 msl), in Parambikulam plateau of Anaimalai Hill complex, Southern Western Ghats, Peninsular India.

| Types | Neotype: BNHS 3584 (ex. CESS182), designated by Mallik et al. 2020. Other specimens: TNHM (Kerala), see Ganesh et al. 2025. |
| Diagnosis | Diagnosis: A species of Ahaetulla having short rostral appendage (vs. long in A. oxyrhyncha comb. nov.; A. anomala, A. laudankia), possessing a white ventrolateral stripe (vs. absent in A. pulverulenta, A. sahyadrensis nom. nov.); absence of a loreal scale (vs. present in A. dispar and A. travancorica sp. nov.); 7 pre-diastemal and 9 post-diastemal maxillary teeth (vs. 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.); we have not found any further morphological difference from other closely related lineages (A. malabarica sp. nov., A. farnsworthi sp. nov., and A. borealis sp. nov.) (Fig. 3 & 13, Table 2, Mallik et al. 2020: 28). Unfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data to their customers.

| Comment | Diet: lizards and other vertebrates (by implication) Synonymy: SMITH 1943 synonymized Dryophis mycterizans isabellinus with A. nasuta but the former was revalidated by Mallik et al. 2020. Distribution: See map in Mallik et al. 2020: 14 (Fig. 4). Habitat: fully arboreal (Harrington et al. 2018, by implication). Types: This species was described based on a single specimen that cannot be traced |
| Etymology | Named in allusion to the isabelline yellow colouration of the dorsal body of the original name-bearing type in live condition (see Wall 1910). |
