Oreoglanis
''Oreoglanis'' is a genus of sisorid catfishes native to Asia.
==Taxonomy==
The taxonomy of this group is currently under discussion and changes seem inevitable as the group is suspected to be non-monophyletic.〔
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 (sometimes with strap-like extensions of the simple principal caudal rays), and a lower lip without a median notch with prominent extensions along the posterior margin.〔 It has been suggested that only the marginal morphology of lower lip can be employed to recognize the two species groups. The ''O. siamensis'' group includes ''O. insignis'', ''O. macropterus'', ''O. setiger'' and ''O. siamensis'', as well as the newer species ''O. immaculatus'' and ''O. jingdongensis'' based on the Chinese distribution of all members of this group. The ''O. delacouri'' group consists of ''O. delacouri'', ''O. frenatus'', ''O. infulatus'', ''O. lepturus'', ''O. macronemus'' and ''O. hypsiurus''.〔〔
