Daboia siamensis (Common name: eastern Russell's viper, [4] Siamese Russell's viper, [5] more) is a viper species which is endemic to parts of Southeast Asia, southern China and Taiwan. [2] [3] It was formerly considered to be a subspecies of Daboia russelii (as Daboia russelli siamensis), but was elevated to species status in 2007. [2]
Dorsally, the color pattern is the same as that of D. russelii , except that the color is more grayish or olive, with small spots between the large spot rows. The venter is suffused with gray posteriorly. [6]
Common names for D. siamensis include eastern Russell's viper and [4] Siamese Russell's viper.
Previously, other common names were used to describe subspecies that are now part of the synonymy of this species: Indonesian Russell's viper for "limitis", and Formosan Russell's viper for "formosensis". [5]
Daboia siamensis is found in Myanmar, Thailand, Cambodia, China(Guangxi Guangdong), parts of India, Taiwan, Nepal and Indonesia (Ende, Bima-Sumbawa, Flores, east Java, Komodo, Lomblen Islands). [3]
Brown (1973) mentions that D. siamensis can also found in Vietnam, Laos and on the Indonesian island of Sumatra. [7] Ditmars (1937) reportedly received a specimen from Sumatra as well. [8] However, its distribution in the Indonesian archipelago is still being elucidated. [9]
As of 2016, antivenoms for Daboia siamensis were produced in India, Myanmar and Thailand. [4]
