Daboia siamensis (Common name: eastern Russell's viper, Siamese Russell's viper, more) is a venomous viper species, which is endemic to parts of Southeast Asia, southern China and Taiwan. It was formerly considered to be a subspecies of Daboia russelii (as Daboia russelli siamensis), but was elevated to species status in 2007.

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.

Common names

Common names for D. siamensis include eastern Russell's viper and 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".

Geographic range

Daboia siamensis is found in Myanmar, Thailand, Cambodia, China(Guangxi Guangdong), parts of India, Taiwan and Indonesia (Endeh, Flores, east Java, Komodo, Lomblen Islands).

Brown (1973) mentions that D. siamensis can also found in Vietnam, Laos and on the Indonesian island of Sumatra. Ditmars (1937) reportedly received a specimen from Sumatra as well. However, its distribution in the Indonesian archipelago is still being elucidated.

Antivenom

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