Kingdom Phylum Class Order Family

Scientific Name: Oligodon pulcherrimus
Species Authority: Werner, 1909
Taxonomic Notes:  The holotype was destroyed during World War II. Tillack & Gunther (2010) recently evaluated the Sumatran species and considered Simotes annulifer var. bipartita Despax, 1912:204 (type locality: “Indes Néerlandaises”) and Oligodon durheimi Baumann, 1913:269, Fig. C. (type locality: “Battak Gebirge, aus einer Höhe von 800 – 1000 m”) as synonyms of this species and described a neotype from Balinka, approximately 7 km southwest of Bukit Tinggi, West Sumatra, Indonesia, ca. 1,200 m. asl.

Justification:
O. pulcherrimus is known only from three records collected in the early 20th Century, and the species is expected to have a true extent occurrence within the intervening area somewhat less than 20,000 km2. The quality of forest habitat throughout this snake's range is known to be declining due to deforestation for agriculture and is likely to continue in the future, and the species is only known from three locations. Therefore the species is listed as Vulnerable and is in urgent need of more research work on its population status, distribution, habitat preferences and threats.
History:
2010 Data Deficient

Geographic Range [top]

Range Description: This species is known from Bakongan (Aceh), Batak Mountains (North Sumatra),and Balinka and Bukit-Tinggi (West Sumatra) in Indonesia. All the localities recorded are between 800 and 1,200 m. asl. and all the records date from the beginning of the the 20th Century. While the extent of occurrence is unclear, the area between the three known localities is around 20,200 km2, and includes large areas of terrain at lower altitudes which is presumed to be unsuitable for this mountain snake. It is therefore provisionally considered to have an extent of occurrence below 20,000 km2.

Population [top]

Population: There are no population data available for this species.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: The sub-district of Bakongan, where this species was collected, consists predominantly of lowland forest with a marshy area. However, localities in the Batak Mountains and Balinka are at high elevations, and therefore montane.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: The species is not utilised or traded.

Threats [top]

Major Threat(s): Despite official protection, the forests in Aceh Selatan remain at high risk of deforestation and are experiencing ongoing illegal exploitation, including large-scale clear-cutting, conversion of forest to palm oil plantations and increased human settlement, all of which are having "severe" ecological consequences (van Beukering et al. 2003).

Conservation Actions [top]

Conservation Actions: There are no direct conservation measures in place for this species at the present time. The type specimen was recorded from Leuser National Park. Research into the population status, distribution, habitat preferences and threats is needed as information regarding this species is sparse.
