Abstract:
Modern accumulations of genetic data offer unprecedented opportunities for understanding the
systematic classification and origins of specific groups of organisms. The genus Sinocyclocheilus is
among the most cave abundant genera in Cyprinidae, with 76 recognized species, belonging to four
species groups. Recent phylogenetic studies have shown that the classification of species groups
within the genus Sinocyclocheilus remains controversial. In this study, we constructed a sequence
supermatrix of 26 species from four species groups of the genus Sinocyclocheilus using the
mitochondrial genome to reveal phylogenetic relationships, historical biogeography and patterns of
species diversification in the genus Sinocyclocheilus. Phylogenetic analysis strongly supports the
monophyletic groups of the three species groups (S. jii, S. cyphotergous, and S. tingi groups) except
the S. angularis group. Phylogenetic analysis showed that S. anshuiensis and S. microphthalmus,
which were recognized as numbers of S. angularis group, formed a strongly supported independent
clade. Therefore, we propose a new species group, the S. microphthalmus group, which contains S.
anshuiensis and S. microphthalmus. Biogeographic reconstruction suggests that the living
Sinocyclocheilus may have originated in north-central Guangxi at the late Eocene and dispersed
outward after a vicariance at 32.31 Million years ago (Ma). Early diversification is focused on the late
Oligocene (ca. 25 Ma), which is related to the second uplift of the Qinghai-Tibetan Plateau and the
lateral extrusion of the Indochina at the Oligocene/Miocene boundary. Our results suggest that two
uplifts of the Qinghai-Tibetan Plateau and climate change in the Miocene may have influenced the
diversification of the Sinocyclocheilus lineage.
