Daboia russelii siamensis is a venomous viper subspecies^[4] that is found only in parts of Southeast Asia, southern China and Taiwan.^[1]

Description

D. r. siamensis

The color-pattern is the same as for D. r. russelii, except that the color is more grayish or olive, with small spots between the large spot rows. Venter suffused with gray posteriorly.^[5]

Common names

Eastern Russell's viper,^[2] Siamese Russell's viper. Previously, other common names were used to described subspecies that are now part of the synonymy of this form: Indonesian Russell's viper for limitis, and Formosan Russell's viper for formosensis.^[3]

Geographic range

Found in Myanmar, Thailand, Cambodia, China (Kwangsi, Kwangtung), Taiwan and Indonesia (Endeh, Flores, east Java, Komodo, Lomblen Islands).^[1]

Brown (1973) mentions that D. russelii (i.e. D. r. siamensis) can also found in Vietnam, Laos and on the Indonesian island of Sumatra.^[6] Ditmars (1937) reportedly received a specimen from Sumatra as well.^[7] However, its distribution in the Indonesian archipelago is still being elucidated.^[8]

Venom

A monovalent antivenin, called "Russell's Viper Antivenin", is made in Thailand by the Thai Red Cross to counteract the venom of this subspecies.^[2]
