Ophryophryne pachyproctus


Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Ophryophryne pachyproctus
Species Authority: Kou, 1985
Taxonomic Notes: The recently discovered populations in Guangxi and Guangdong provinces in China have been assigned to this species by M.W.N. Lau (pers. comm.) who compared the specimens with the original description, and who consulted with Zhao Ermi. Further clarification is needed by comparing specimens from Yunnan with those from Guangxi and Guangdong.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Michael Wai Neng Lau, Fei Liang, Peter Paul van Dijk, Steven Swan
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description: This species is known from the Annamite Mountains in Viet Nam and Lao People's Democratic Republic, and the mountains of northern Viet Nam as well as southern Yunnan (Mengla), western Guangxi (Dawangling Nature Reserve) and southeastern Guangdong (Baiyong Nature Reserve and Heweishan) in China. It probably occurs more widely than current records suggest, especially in areas between known sites. In Viet Nam it is known between 250m asl (northern Viet Nam) to 1,700m asl (Kon Tum plateau) (Orlov et al., 2000). In China it has been recorded from 470-900m asl.

Population [top]

Population: This species was originally thought to be very rare when it was known only from Yunnan. Recent information suggests that it is more common in the Baiyong National Nature Reserve in China and also in Viet Nam.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It inhabits evergreen broadleaf forest and the associated small hill streams. It is found near and in forest streams where it also breeds. Males have been observed calling from foliage about 2.5m above the ground.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): There is ongoing forest loss, and threats from dams and power plants.

Conservation Actions [top]

Conservation Actions: Its range includes several protected areas in both Viet Nam and Lao People's Democratic Republic. In China it occurs in the following National Nature Reserves: Dawangling, Baiyong, and Xishuangbanna. More information is needed about the species' population status, distribution, taxonomy and natural history before conservation measures can be determined.
