Etymology

The species name annamensis is derived from "Annam," the name given to the French protectorate in central Vietnam, prior to that country's independence, where the holotype was collected.[3]

Phylogeny

Oligodon annamensis is a member of the genus Oligodon, a genus common throughout central and tropical Asia.[4] The genus belongs to the snake family Colubridae, the largest snake family, with member species being found on every continent except Antarctica.[5]

Description

The head of the snake is short and rounded,[2] with the snout being slightly longer than it was broad. The eyes are moderately large, with round pupils.[3] A holotype for the species was 24.9 cm in total length, with a 2.9 cm tail. The back and head of the snake are light brown, with white blotches that are edged in black. The underside is white.[3]

Habitat and ecology

The habitat and ecology of this species is poorly known. Based on data for other members of Oligodon, O. annamensis is thought to be oviparous, or egg-laying, and terrestrial in its habits.[1]

Distribution

The species is known only from two specimens, and so its distribution is poorly understood.[1] The holotype was collected from central Vietnam, and the other from Lam Dang province.[2] The species is thought to be endemic to Vietnam.[1]

Conservation

The conservation threats to O. annamensis are not known, because the species is only known from two specimens. The area from which these are collected is not under any sort of protection, and is threatened by deforestation.[1]
