Remarks Males differ from females by the following characters: larger and more prominent tubercles on snout tip and anterior portion of lachrymal than in females; variable-sized tubercles present on side of branched anal-fin rays, distributed from second to fourth ray in two or three rows at distal portion of each ray (vs. absent in females); anal fin with a truncate distal margin (vs. slightly convex in females); anal fin shorter than in females; males slightly smaller in size; and two lobes of lower lip separated by a median interruption on lower jaw (vs. closely in contact with each other in females).

Diagnosis

Possesses six vertical black bars, each two scales in width, on the flank. These bars are more indistinct in adult males than in females, absent in some larger individuals. Presence of second primary vertical black bar positioned posterior to the base of the last simple dorsal-fin ray and a longitudinal black stripe extending along the lateral line on the flank of adults, which it shares with other congeners (Acrossocheilus fasciatus, Acrossocheilus jishouensis, Acrossocheilus parallens and Acrossocheilus wenchowensis). Shares with Acrossocheilus jishouensis and Acrossocheilus parallens in having vertical bars not extending beyond the lateral line on the flank, but can be diagnosed from them in having a stout (vs. slender) last simple dorsal-fin ray. Can be further distinguished from Acrossocheilus jishouensis by the presence of small serrations along the posterior edge of the last simple dorsal-fin ray (vs. absence) and from Acrossocheilus parallens

by the presence of oblong, black blotches on the membranes between the dorsal-fin rays (vs. absence) (Ref. 85613).

Description: dorsal fin with three simple and eight branched rays; anal fin with three simple and five branched rays; pectoral fin with one simple and 14 or 15 branched rays; pelvic fin with one simple and eight branched rays (Ref. 85613).
