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]

Description

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

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]

Geographic range

Daboia siamensis is found in Myanmar, Thailand, Cambodia, China(Guangxi Guangdong), parts of India, Taiwan, Nepal and Indonesia (Ende, 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]

Antivenom

As of 2016, antivenoms for Daboia siamensis were produced in India, Myanmar and Thailand. ^[4]
