In this work, a new species of the genus Oreonectes is described, named Oreonectesdamingshanensis Yu, Luo, Lan, Xiao & Zhou, sp. nov. , collected from the Damingshan Mountains of the Guangxi Zhuang Autonomous Region, China. Phylogenetic trees constructed based on the mitochondrial Cyt b showed that the new species represents an independent evolutionary lineage, with uncorrected genetic distances ( p -distance) from congeners ranging from 6.1% to 8.9%. Morphologically, the new species can be distinguished from five other species of the genus by a combination of characters. The discovery of this new species raises the number of known species of Oreonectes from five to six. Our study suggests that O.platycephalus may be a complex containing multiple species and that previously recorded areas need to be further delimited and reevaluated.
