Abstract

Abstract

Guigarra cailaoensis sp. nov. , a new genus and species of Labeoninae, was collected from Guangxi Zhuang Autonomous Region, China. It differs from all other genera within Labeoninae by a unique combination of the following characters: (1) rostral cap smooth with posterior margin slightly serrated; (2) upper lip well developed and covering most of upper jaw; (3) gular disc present with crescentic torus, not forming horseshoe shape; (4) boundaries of torus, labrum, and pulvinus on gular disc inconspicuous; (5) posterior edge of labrum free, without notch. Molecular phylogenetic analysis of three gene datasets indicated that the new genus formed a monophyletic clade and was closely related to Discogobio and Discocheilus. Both morphological and molecular phylogenetic analyses indicated that Guigarra cailaoensis sp. nov. differs from all known labeonin genera and is thus described here as a new genus and species.
