Holotype: TMNH 8650212, 108.1mm SL. Paratypes (12): TMNH 8650211, 8650213-8650223, 55.5mm - 123.36mm SL. All paratypes except 8650221 and 8650222 are kept with the holotype. The latter two are kept at the Guangxi Museum.


Known only from the type locality: Shadong Cave, Lingyun County, Guangxi, China (24o20’N, 106o32’E). This species coexists at the type locality with Sinocyclocheilus lingyunensis and Triplophysa lingyunensis This in one of only two known instances where three troglobitic fishes are found together, the other being Garra typhlops, Garra lorestanensis and Eidinemacheilius smithi in Iran.


No details known.


A member of the subfamily Barbinae. Most closely related to Sinocyclocheilus jii which may be a troglophilic species (Chen and Yang, 1993b). Wang and Chen (1998) revised the diagnosis of the genus Sinocyclocheilus.

Biological Notes

Shadong Cave also contains a very troglomorphic crustacean Macrobrachium lingyunense Li, Cai and Clarke, 2006 (Crustacea: Decapoda: Palaemonidae) (Pan, Hou and Li 2010).
