وصف مختصر

الأشعة الظهرية الناعمة (المجموع) : 12; أشعه شرجية لينه: 8; فقرات: 33. This species is a member of the Psilorhynchus balitora species group but it can be diagnosed from other members of the group by possessing longer caudal peduncle 17.8-20.5% SL (vs. 8.9-15.2 in P. balitora, P. brachyrhynchus, P. breviminor, P. nepalensis, P. pavimentatus, P. gokkyi, P. piperatus, P. hamiltoni and P. rahmani). It differs from P. amplicephalus by its smaller eye (24.5-29.2% HL vs. 32.4-36.0) and fewer lateral-line scales (30-31 vs. 32); and from P. breviminor, P. nepalensis, P. rahmani and P. pavimentatus in having a greater head depth (59.4-70.4% HL vs. 51.0-55.8 in P. breviminor, 50.0-56.8 in P. nepalensis, 53.3-59.2 in P. rahmani and 54.5-59.0 in P. pavimentatus). It is distinguished from all congeners by its caudal-fin pattern consisting of two black bars, one incomplete bar near the base of the upper lobe, and a complete bar across the centre of the fin, traversing from the upper to the lower margin of the fin (Ref. 93984).
Found in a cool, shaded and swiftly flowing river with a gravel bottom, rocky bed substrate and numerous riffles. Usually occurs on sandy substrate with pectoral fins spread horizontally while feeding at the bottom and adhering to rocks while at rest (Ref. 93984).
