Kingdom Phylum Class Order Family
ANIMALIA CHORDATA ACTINOPTERYGII PERCIFORMES ODONTOBUTIDAE

Scientific Name: Terateleotris aspro
Species Authority: (Kottelat, 1998)

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2012
Date Assessed: 2011-11-11
Assessor(s): Kottelat, M.
Reviewer(s): Rainboth, W. & Allen, D.
Justification:
This species is only known from the Xe Bangfai drainage, Lao PDR. It has not been observed upstream of the underground course of the Xe Bangfai. It had only been observed in the Xe Bangfai upstream of the impact of the discharge from the Nam Theun 2 power plant, however it might be present in adjacent drainages. Logging, deforestation and agriculture occur in the area, with associated impacts on the aquatic environment observed. This species is assessed Endangered, based on the Extent of Occurrence (EOO) of between 3,500 - 5,000 km2, and an Area of Occupancy of c.350 km2, an estimated number of locations of 3-5, and ongoing impacts from degradation of water quality arising from logging and agricultural activities within the catchment.

Further research is needed to confirm the species' distribution as it can be expected to be present in other adjacent sub-catchments, and it should be reassessed if further populations are found.

Geographic Range [top]

Range Description:

The species is only known from the Xe Bangfai drainage, Lao PDR, where it has been observed within a restricted area downstream of the underground course of the Xe Bangfai and upstream of the impact of the release of the Nam Theun 2 power plant discharge. The species may be present in adjacent drainages, however it has not yet been observed from outside the known locations within the Xe Bangfai (M. Kottelat pers. comm. 2011; W. Rainboth pers. comm. 2011).
