Oreoglanis pangenensis, new species, is described from the Pange River, upper Brahmaputra River basin, Apatani plateau, Lower Subansiri District, Arunachal Pradesh, India. It belongs to the O. siamensis species group and is distinguished from all its congeners by a combination of two types of projections on the ventroposterior margin of the maxillary barbel: The proximal one-third with lobulate projections and the distal two-thirds with laciniate projections. It is further distinguished from members of the O. delacouri group in having a median notch on the posterior margin of the lower lip, an entire lower lip margin, and (except for O. temiicauda) an emarginate caudal fin. © 2015 by Verlag Dr. Friedrich Pfeil, München, Germany.
