Acrossocheilus monticola (GÜNTHER, 1888)

SynonymsTop ↑

Crossochilus monticola Günther, 1888

Etymology

Acrossocheilus: from the Ancient Greek ἀ- (a-), meaning ‘without’, κροσσός (krossós), meaning ‘fringe, tassel’, and χείλος (cheílos), meaning ‘lip’, in reference to the lack of barbels in members of this genus.

monticola: from the Latin monti, meaning ‘montane’, and cola, meaning ‘like’, in reference to the natural habitat of this species.

Classification

Order: Cypriniformes Family: Cyprinidae

Distribution

Apparently endemic to the upper Yangtze River basin, China.

Type locality is ‘mountain-stream fiowing into the Ichang gorge of the Yangtsze River’.

Maximum Standard Length

100 – 150 mm.

Diet

Wild fish are known to feed on small, benthic invertebrates and graze biofilm from rocks and other solid surfaces.

NotesTop ↑

The genus Acrossocheilus is restricted to southern China, northern Vietnam and northern Laos. It can be distinguished from related genera by the following combination of characters: rostral fold present; lips fleshy and continuous around corners of mouth; lower lip with a median interruption; mouth inferior; horny sheath on lower jaw; two pairs of barbels; last simple ray of dorsal fin osseous with a serrated or smooth posterior margin.

Members of the genus are characterised by possessing a particular number of dark vertical bar on each flank, and A. monticola uniquely possesses seven or eight bars, each of which is 1–3 scales wide.
