Balitoridae, the hillstream loaches or river loaches, is a family, of small fish from South, Southeast and East Asia. The family includes about 202 species. They are sometimes sold as "lizardfish" or "flossensaugers". Many of the species are popular for aquaria, species in the genus Sewellia are most commonly sold in the aquaria trade.

This species is found in the Brahmaputra River ofAssam. This is one of two species in the genus Acanthocobitis, alongside the type species, A. longipinnis.

This species is the type species of the genus Acanthocobitis.
