Relevant Information:

Description: Dorsal soft rays (total): 6; Anal soft rays: 9 - 10; Vertebrae: 31 - 32. Distinguished from all its congeners by the following unique combination of characters: slender body (body depth at anus 8.2-10.3% SL; depth of caudal peduncle 3.5-4.5% SL); extremely narrow head (head width 17.5-20.2% SL); small and close-set eyes (eye diameter 6-10% HL; interorbital distance 20-26% HL); short nasal barbels (11-17% HL); the presence of 6-8 serrae along the posterior edge of the pectoral spine and 8-9 branchiostegal rays; and caudal fin strongly forked with pointed lobes. Etymology: The genus name Pseudobagarius: Tautonymous with Akysis pseudobagarius, proposed for members of the “pseudobagarius group” of Akysis; pseudo-, false, referring to striking (but phylogenetically false) resemblance to the sisorid genus Bagarius. The specific name similis: Resembling, referring to close resemblance to P. pseudobagarius.

IUCN Red List

There is insufficient information about the geographic distribution and population size of this species for an accurate assessment and it is assessed as Data Deficient. Despite earlier assessments as Vulnerable for this species by Vidthayanon (2005), there are no empirical data to justify this assessment, but needs updating (IUCN 2012).
