|Scientific Name:||Pseudomystus siamensis|
|Species Authority:||(Regan, 1913)|
Leiocassis albicollaris Fowler, 1934
Leiocassis siamensis Regan, 1913
|Taxonomic Notes:||Validate its genus into Pseudomystus from known similar catfish Lieocassis.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Allen, D. & Smith, K.|
This is an abundant species at least throughout the middle and lower Mekong River drainage. In the absence of any major threats identified for this species, it is assessed as Least Concern, however further research into threats is required.
|Range Description:||The species is widely distributed throughout mainland southeast Asia. It is found in the lower Mekong, Mae Klong, and Chao Phraya basins (Kottelat 1998), and river systems on both slopes of the Malay Peninsula, and in coastal drainages in southeastern Thailand (Vidthayanon et al. 1997).
In the Mekong, it is found in major tributaries (e.g., the Xe Kong; Kottelat 2011).

|Population:||There is no information on the population and its trends for this species, but survey data indicate that it is still an abundant species, particularly in the Mekong River drainage.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||The species occurs in a wide range of habitats including rivers and streams, marshlands, and peat swamps. It is slightly adaptive to impounded waters and man-made wetlands. Migratory movements are uncertain, but seems to undertake seasonal movements (Baran et al. 2005).|
|Movement patterns:||Full Migrant|
|Use and Trade:||This species is caught as a food fish in artisanal fisheries. Juveniles are often caught and exported as ornamental fish.|
|Major Threat(s):||The threats to this species are unknown, since there is limited information on the biology of this species and therefore the impact of potential threats (especially those of an anthropogenic nature) remains unknown. The current threats to aquatic biodiversity in all of its known distribution have also not been adequately identified.|
|Conservation Actions:||There is insufficient information on the distribution, biology and potential threats for this species. Catch data for this species are also needed.|
