Common name: Eastern Russell's viper.[2]  
Daboia russelii siamensis is a venomous viper subspecies[3] found in parts of southeast Asia, southern China and Taiwan.[1]


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.[4]

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.[5] Ditmars (1937) reportedly received a specimen from Sumatra as well.[6] However, its distribution in the Indonesian archipelago is still being elucidated.[7]


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]
