Oreoglanis is a genus of fish in the family Sisoridae native to Asia. These fish live in fast-flowing streams in China, mainland Southeast Asia and the Indian subcontinent.^[1] They are mainly distributed in the Mekong, upper Salween and Irrawaddy River drainages.^[2] They range from the Brahmaputra basin to the Lam River drainage in central Vietnam.^[3] They are easily distinguished from other catfishes by their strongly depressed head and body and greatly enlarged paired fins that have been modified to form an adhesive apparatus.^[1] The flattened shape of these fish and the large pectoral and pelvic fins provide essential adhesion in the fast-flowing waters they live in.

Taxonomy

The taxonomy of this group is currently under discussion and changes seem inevitable as the group is suspected to be non-monophyletic.^[1] Based on morphology, Oreoglanis has been divided into two species groups. According to the original description of these groups, the O. siamensis species group is distinguished by having an emarginate caudal fin, and a lower lip notched medially with an entire or weakly laciniate posterior margin, while the O. delacouri species group is distinguished by having a lunate caudal fin and a lower lip without a median notch with prominent extensions along the posterior margin.^[1] It has been suggested that only the marginal morphology of lower lip can be employed to recognize the two species groups.^[2]
