Scientific Name: Hypsibarbus oatesii (Boulenger, 1893)
Taxonomic Notes: Hypsibarbus oatesi was described from Nampandet, Myanmar (Boulenger 1893). The species was originally described as a species of Barbus, but was reassigned to the genus Hypsibarbus by Rainboth (1996). This species is often confused with H. myitkyinae, but can be distinguished chiefly by scale counts (Rainboth 1996). This species, along with H. myitkyinae, has often been the source of taxonomic confusion in the past. Pillay (1951) placed both species in synonymy with Puntius sarana based on similar scale counts, a taxonomic act that some authors (e.g. Talwar and Jhingran 1991) follow.  Both Hypsibarbus species differ from P. sarana and its close relatives in external characters of scale morphology, dorsal fin spine serration and mouth inclination (Rainboth 1996).

The species is likely to be under-sampled given the low level of survey effort in this part of Myanmar. The species has a relatively wide distribution (estimated 40,000 km²) however it is only known from three localities. The threats to the species and the impacts of proposed dams in the Salween catchment is unknown. The species is therefore assessed as Data Deficient.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This species was described from near Nampandet (town) which is on the western slope of the Shan plateau, Myanmar and on the border between the Salween and Ayeyarwaddy catchments so it is unclear which catchment the types came from, however other specimens found came from the Salween catchment. The species is known from the southern half of the Shan Plateau.
Countries occurrence:
Myanmar (Myanmar (mainland))

Population [top]

Population:There is no information on the population and its trends for this species.
Current Population Trend:Unknown
Additional data:
Continuing decline of mature individuals:Unknown

Habitat and Ecology [top]

Habitat and Ecology:Little is known regarding the species habitat needs apart from that it inhabits rivers (not small streams), in flowing waters.
Continuing decline in area, extent and/or quality of habitat:Unknown

Use and Trade [top]

Use and Trade: This species is caught for food in subsistence fisheries.

Threats [top]

Major Threat(s): The threats to this species are unknown, since there is little information on the biology of this species and therefore the impact of potential threats (especially those of an anthropogenic nature) remains unknown. In the Shan Plateau there are dams planned in the Salween system which may impact the species.

Conservation Actions [top]

Conservation Actions: More research about the distribution and the biology of this species is needed, as there is insufficient information available. Potential threats to this species also need to be identified.
