Etymology: Stenorynchoacrum: Sten is derived from Green stenos, means narrow; ryncho from Greek rhynchos, means snout; and from Greek acr, means the extremities of the body (snout, ears or trotters). Thus, rynchoacrum means ventral margin of rostral cap. Stenorynchoacrum alludes to the narrow and undeveloped rostral cap of this genus.; xijiangensis: Name alludes Xi Jiang, the drainage of the type locality..

简单描述
型态特徵 | 形态测量图
背的软条 (总数): 11; 臀鳍软条: 8; 脊椎骨: 35 - 37. Stenorynchoacrum xijiangensis differs from all species belonging to Labeoninae by the following characters: middle part of rostral cap undeveloped, narrow, only covering the base of the upper jaw, both sides of rostral cap well developed and extending upward, rostral cap connected the lower lip, both lateral part of which free, as the result of a long postlabial groove separating the posterior margin of lateral part of lower lip and the isthmus, the median part of lower lip protrudes to form a round fleshy pad, whose posterior margin continuous with the mental region, no crescentic fold surrounding the fleshy pad (Fig. 2). Other diagnostic characters include: ventral margin of rostral cap unfringed, upper lip regresses to form a row of thin, tiny lobes adnated to upper jaw, the posterior margin of lower jaw connected the anterior part of lower lip, lower lip well developed, variable papillae scattered on rostral cap and lower lip, the anterior margin of upper and lower jaws born flexible, cornified sheath, two pairs of barbels, pharyngeal teeth in 3 rows, and dorsal fin with eight branched rays (Ref. 95674).
Inhabits underground caves connected to the surface river in the Karst area. Remains in
the underground caves in the dry season and swims upward into the rivers during the flood season (Ref. 95674).
