Differs from members of the genus by the following characters: maxillary barbels almost equal to rostral barbels; pelvic fin 83.7-89.4%, the distance between the ventral-fin origin to anal-fin origin; a longitudinal wide black stripe extends along the posterior lateral line; irregular brown pigments present on both sides of the body. Differs further from its congeners, except Parasinilabeo longcorpus by having pharyngeal teeth formula 2.3.5-5.3.2. Can be differentiated from Parasinilabeo assimilis by having more depressed body; from Parasinilabeo microps by having fewer lateral lines (38-39 vs. 41-44) and shorter caudal peduncle length (14.1-16.2% vs. 17.8-19.0% SL); from Parasinilabeo maculatus by its fewer lateral lines (38-39 vs. 40-42); fewer circumpeduncular scales (16 vs. 18); fewer branched dorsal-fin rays (7 vs. 8); shorter more slender caudal-peduncle, shorter snout (41.6-45.7% vs. 47.9-50.5% HL); larger eyes (24.8-27.4% vs. 19.4-23.6% HL) and the narrower interorbital space (41.9-47.7% vs. 51.8-56.1% HL); from Parasinilabeo longcorpus by its less slender body; and from Parasinilabeo longibarbus by having rostral cap with vertical grooves compared to smooth (Ref. 72393).
