The colubrid genus Boiga Fitzinger 1826 comprises 37 nominal species of which 17 occur in India (Uetz et al. 2023). Seven of the Indian species (B. beddomei, B. dightoni, B. flaviviridis, B. forsteni, B. nuchalis, B. thackerayi, B. trigonata) are known from the Western Ghats (Narayanan et al. 2023), but only two (B. flaviviridis and B. forsteni) have been recorded in forested areas of both the Eastern and Western Ghats (Ganesh et al. 2020a). The Yellow-green Catsnake (Boiga flaviviridis) was originally described from Berhampur, Odisha, India, and has subsequently been recorded from forested regions across much of peninsular India (Vogel and Ganesh 2013; Dharmendra et al. 2016; Sharma et al. 2016; Choure et al. 2021; Kalki et al. 2021; Fig. 1). In the Western Ghats, the species is known from only a handful of records in the southern parts of the range (Vogel and Ganesh 2013; Ganesh et al. 2020a, 2020b).
