 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.

Yu et al. (2021) obtained a mitochondrial genome of S. xiaotunensis (see below). They found that it lead to a clade of S. xiaotunensis with S. altishoulderus and S. furcodorsalis. [Note: at the time of publication of Yu et al. (2021) (May 2021) it does not appear that S. xiaotunensis has been formally described].
