“…Although several recent studies emphasized the importance of biogeography in shaping the cryptic diversity among 'similarlooking' snake species in eastern India in contrast to Sri Lanka, e.g. Oligodon russelius vs. O. arnensis (see Bandara et al, 2022) and Fowlea piscator vs. F. unicolor (see Amarasinghe, et al, 2022), we are not confident enough to consider L. s. striatus and L. s. sinhaleyus as two distinct species.…”

The snake fauna of the Andaman archipelago was studied over a duration of four years across twenty islands. This paper presents information on the species richness and taxonomy of snakes of the Andaman archipelago along with observations on natural history and a review of their distribution records, including new, precise ones. Natural history observations for some of the recently re-evaluated species are presented herein for the first time. Field observations on snakes made during this study are supplemented with a compilation of data from specimen collections (n=34) examined in various museums. Based on this dataset and reliable, verified literature records, distribution maps are presented for all the snake species in the Andaman Islands. In addition, unsubstantiated old records of certain species that are shown to be ambiguous are removed from the updated checklist presented here, which consists of 23 species from 22 genera and eight families. Nine of these terrestrial (non-marine) species (56%) are endemic to the Andaman Islands. However, some of the non-endemic species are still in need of a proper molecular taxonomic assessment. The majority (70%) of species are of Least Concern, with 13% of the species being Data Deficient, 9% being Endangered, 5% of the species still in need of evaluation of their conservation status and 4% each being Near Threatened and Vulnerable.

Tropidonotus nicobarensis Sclater, 1891 is an enigmatic snake currently referred to the natricine genus Hebius Thompson, 1913. No specimens have been recorded since the original discovery of the name-bearing type in the late 19th century, which was allegedly collected on Kamorta Island in India’s Nicobar Archipelago. Recently, a second observation of this species was reported from Havelock Island (Swarajdweep) in the nearby Andaman Archipelago. However, the snake in question is clearly conspecific with another natricine, Thamnophis saurita (Linnaeus, 1766), native to eastern North America. This discovery prompted us to examine the type specimen of Tropidonotus nicobarensis, which revealed that it too is conspecific with Thamnophis saurita. The provenance of the Tropidonotus nicobarensis type specimen and the Havelock Island snake are discussed, with the latter likely representing an introduced animal.
