''Leiocassis'' is a genus of bagrid catfishes found mostly in Southeast Asia with some species occurring in China. This genus has a confused taxonomy and there is uncertainty surrounding the number of valid species.〔 Certain East Asian bagrids formerly placed in this genus have been moved to ''Pseudobagrus''.〔 In 2006, Heok Hee Ng considered the genus ''Leiocassis'' to be restricted to Sundaic Southeast Asia and Borneo and only a handful of species as valid (''L. aculeatus'', ''L. collinus'', ''L. hosii'', ''L. micropogon'', ''L. poecilopterus'', and ''L. tenebricus'').〔 The members of ''Leiocassis'' have an elongate narrow head and a prominently protruding snout.〔 == Species == There are currently 13 recognized species in this genus: * ''Leiocassis aculeatus'' H.
