Species

This genus has a confused taxonomy and there is uncertainty surrounding the number of valid species.^[1] Certain East Asian bagrids formerly placed in this genus have been moved to Pseudobagrus.^[1] 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).^[1]

There are currently 14 recognized species in this genus:^[2][3]
