Kingdom Phylum Class Order Family
Animalia Chordata Reptilia Squamata Colubridae

Scientific Name: Oligodon deuvei David, Vogel & van Rooijen, 2008
Taxonomic Notes: This snake is a member of the Oligodon taeniatus group, and prior to its description had been confused with the nominate species (David et al. 2008). Confusion may also be possible with the similar O. barroni and with O. mouhoti, since at least one known specimen exhibits patterning closely resembling the latter species (David et al. 2008).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012
Date Assessed: 2011-08-30
Assessor(s): Nguyen, T.Q. & Thy, N.
Reviewer(s): Bowles, P. & Cox, N.A.
Listed as Least Concern on the basis that, while this species is poorly-known, may be rare, and has an apparently disjunct distribution, it is not apparently subject to any major threats and is known from protected areas.

Geographic Range [top]

Range Description:This snake has been recorded from isolated localities in Cambodia, southern Viet Nam and Lao PDR, and is expected also to occur in northeastern Thailand (David et al. 2008, Nguyen et al. 2009). In Viet Nam it is known from Dong Province, Ho Chi Minh District and Cat Tien National Park (Geissler et al. 2011). It is known in Cambodia from a single specimen collected from Che Teal Chrum Village, Pursat Province. In Lao PDR it has been recorded only from Vientiane Prefecture, where it is known from the vicinity of Vientiane, Tha Ngon and Wattai. This species has historically been confused with related forms and its true distribution is in need of clarification.
Countries occurrence:
Cambodia; Lao People's Democratic Republic; Viet Nam

Population [top]

Population:No population data are available. The original description includes 17 specimens collected over a period since 1932 (David et al. 2008); due to historical confusion over the taxonomic identity of this species no inferences can be made regarding the abundance of this snake. Since the original description only three additional specimens, all from Cat Tien National Park, have been taken (Geissler et al. 2011).

Habitat and Ecology [top]

Habitat and Ecology:This is a small, secretive terrestrial snake. Deuve (1970) encountered his specimens of “Oligodon taeniatus”, which turned out to be mostly Oligodon deuvei, during all seasons. Juvenile specimens appeared during the rainy season (July to October). According to Deuve (1985), specimens were collected at day time on the ground, under various pieces of vegetation, or in gardens. It is predominantly crepuscular, but has been observed actively foraging during daytime (Geissler et al. 2011). In Cat Tien, animals have been found along river banks neighbouring rural areas, in disturbed lowland forest. Stomach contents include frogs and tadpoles, suggesting that this species is semi-aquatic (Geissler et al. 2011). The one known Cambodian specimen was collected from villagers near disturbed lowland forest; the precise details of the habitat where the animal was taken are uncertain (T. Neang pers. comm. 2011).
Systems:Terrestrial; Freshwater

Use and Trade [top]

Use and Trade: No use or trade information is available for this species, however there is no commercial demand for species of Oligodon.

Threats [top]

Major Threat(s): As this snake has been found in artificial habitats such as gardens and disturbed forest, and in open areas, it is uncertain whether it is likely to be threatened. Forest clearance to make room for villages may impact this species, but it is not clear whether this represents a major threat (T. Neang pers. comm. August 2011).

Conservation Actions [top]

Conservation Actions: No species-specific conservation measures are in place. This snake has been found in protected areas in Cambodia and Viet Nam. Research is needed to clarify the distribution and population status of this snake, and to determine whether it it is likely to be at risk from land clearance.
