Relevant Information:

Description: Dorsal soft rays (total): 6; Anal soft rays: 3 - 4; Vertebrae: 37 - 41. Lower lip lacking a median notch and having an entire posterior margin. Caudal fin emarginate. Male genital papilla immediately behind the anus in a depression terminating posteriorly with a straight transverse wall. Found in mountain streams. Oreoglanis is distinguished from Glyptosternon, Glaridoglanis, Euchiloglanis, Pareuchiloglanis and Parachiloglanis by having a continuous post-labial groove. It is distinguished from Pareuchiloglanis, Glyptosternon, Euchiloglanis, Myersglanis, and Parachiloglanis by having heterodont dentition in the lower jaw characterised by an inner row of pointed teeth and an outer row of short, spatulate (shovel-like) teeth (vs. a single band of conical teeth). Oreoglanis is distinguished from Pseudexostoma by having upper jaw teeth pointed, in two patches, joined into a continuous band (vs. heterodont dentition in two separated patches). It is distinguished from Exostoma by having the upper jaw teeth pointed, in two patches, joined into a continuous band (vs. having oar-shaped, distally flatted teeth in two separated patches), and 16–18 (vs. 10–11) branched pectoralrays. Etymology: The specific name macroptera: macro-, from makrós, long or large; ptera, from pterón or ptéryx, fin, referring to its large pectoral fins, which extend far beyond belly and dorsal-fin base. Remarks: Still found on some online sources as Oreoglanis macropterum.

IUCN Red List

Although there is little information on the distribution, population (and its trends), and biology of Oreoglanis macropterus (macroptera), available published data from field surveys indicates that it is a relatively common species. Given the fact that this species inhabits areas where fishing and other anthropogenic pressures are relatively low, it is therefore assessed as Least Concern, but needs updating, (IUCN 2010).
