Etymology: Psilorhynchus: Greek, psilos = hairless + Greek, rhyngchos = snout (Ref. 45335); piperatus: From the Latin adjective 'piperatus', meaning peppered, in allusion to the speckling on the caudal fin.

Morphology | Morphometrics
soft rays: 8;
Vertebrae: 35. Distinguished from all its congeners by its unique caudal-fin pigmentation pattern, consisting of an approximately symmetrical pattern of small black blotches on both upper and lower caudal-fin lobes. Can be further diagnosed from other species of Psilorhynchus by the combination of the following characters: snout length 53-55% HL; ventral surface between paired fins with a broad rectangular scale-less patch; dorsal fin with 9 branched rays; pectoral fin with 5 unbranched rays; caudal fin with 9+9 rays; scales on lateral line 32-33; lateral sides of body marked with 6 indistinct round to squarish dark-brown blotches, arranged in a longitudinal row; dorsal saddles deep, extending 3-4 scale rows downwards from the dorsal surface, in contact with the round to squarish dark brown blotches, arranged in a longitudinal row on flank (Ref. 85329).
Found in a swift-flowing river with dense riparian vegetation and a substrate of sand, gravel and small boulders (Ref. 85329).
