Leiocassis is a genus of bagrid catfishes found mostly in Southeast Asia with some species occurring in China.

The members of Leiocassis have an elongate narrow head and a prominently protruding snout. [1]

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 Tachysurus . 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. aculeata, L. collina, L. hosii, L. micropogon, L. poeciloptera, and L. tenebrica). [1]

There are currently 7 recognized species in this genus: [2]

As of August 2025, both FishBase and WoRMS list 14 species. [5] [6]
