Triplophysa xiangxiensis

(Yang, Yuan and Liao 1986) Chen, Yang and Xu 1992

Triplophysa xiangxiensis
Illustration from Weber, Proudlove and Nalbant (1998)
CypriniformesCobitoidei Nemacheilidae


Noemacheilus xiangxiensis  Yang, Yuan and Liao 1986




Holotype: HAU 8401 85.0mm "body length". Paratypes: HAU 8601‑8602 45.0mm‑67.0mm "body length", KIZ 863001.


Known only from the type locality: Feihu Dong (= cave), north‑west Longshan County, Xiangxi, Hunan Province, China (29o29’N, 109o25’E).


Nothing known, the specimens were collected "from the subterranean water at a depth of 20m under the ground surface".


Chen, Yang and Xu (1992) re-examined the type specimens of this species and of Noemacheilus gejiuensis. They concluded that both were members of the genus Triplophysa because of an absence of a procesus dentiformis on the upper jaw and the presence, in males, of a raised tuberculate area below the nares and thickened tuberculate pads on the back of the pectoral fin rays. Sgouros et al. (2019) found that T. xiangxiensis is sister species to T. rosa. A good comparison of subterranean Triplophysa species is provided by Wu et al. (2018).
