Etymology: Acrossocheilus: Greek, akro = topmost, summit + Greek, krossos = tassel, fringe (Ref. 45335).
Eponymy: Dr Martin Kreyenberg (1872–1914) was a German physician and naturalist. [...] (Ref. 128868), visit book page.

Environment: milieu / climate zone / depth range / distribution range
Ecology

Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 15.5 cm SL male/unsexed; (Ref. 85613); common length : 16.0 cm TL male/unsexed; (Ref. 35840)
Dorsal soft rays (total): 11; Anal soft rays: 8. 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).
