Types

Holotype: KIZ 865949 105mm SL. Paratypes KIZ (unnumbered) 7 specimens 68-93mm SL.

Distribution

Known only from the type locality: Jiuxing Limestone Cave, Jiuxiang, Yiliang County, Yunnan Province, China (25o24'N, 103o27'E). Two other species are also found in this cave: Triplophysa yunnanensis and Paralepidocephalus yui (Yang and Chen 1993).

Habitat

Details of the habitat are discussed in the paper containing the original description but in Chinese. I have not been able to obtain a translation so no details are given here.

Systematics

A member of the subfamily Barbinae and most closely related to Sinocyclocheilus angustiporus (based on the serrated last ray of the dorsal fin). Wang and Chen (1998) revised the diagnosis of the genus Sinocyclocheilus.

Li at al. (2018) obtained a complete mitochondrial genome of Sinocyclocheilus oxycephalus. This allowed them to show that 11 species in the genus comprised a monophyeltic group: S. grahami, S. wumengshanensis, S. oxycephalus, S. ranganensis, S. jii, and the hypogean S. anophthalmus, S. anshuiensis, S. altishoulderus, S. bicornutus, S. rhinocerous and S. furcodorsalis. This grouping does not agree with the clades proposed by Zhao and Zhang (2009) who placed the hypogean species in three separate clades angularis, cyphotergous and tingi. This situation will require further study to resolve.

Conservation Status

TLO [VU D2:2.3:1996]

R (IUCN, 1990). Currently the type locality is a show cave and it is prohibited to catch this species without permission. Previously many were caught and the population size decreased. This species was listed as a second class protected species of Yunnan Province in 1989 (Yue and Chen 1998:107-109).
