Anal soft rays: 10 - 11; Vertebrae: 38 - 40. Having the following autapomorphic characters: postcleithral process expanded; suborbital tubule 3 and respective i5 branch and pore of infraorbital latero-sensory canal absent. Shares with Nemuroglanis lanceolatus the following eight apomorphies: five or six pairs of pleural ribs; dorsal caudal plate supports only six principal caudal-fin rays; ventral caudal plate much smaller than dorsal caudal plate, supporting only three or four rays; dorsal caudal-fin lobe with five or fewer branched rays; dorsal caudal-fin lobe very long, usually greater than 40% SL; ventral caudal-fin lobe usually with nine to 13 rays; ventral caudal-fin lobe with only three or four branched rays; and caudal fin lanceolate. Differ further from its congeners by possessing fewer vertebrae, 38-40 and fewer anal-fin rays, 10-11; maxillary barbel length , 38.8-55.8% SL; and anal-fin base length, 13.9-16.2% SL .
