Description
A new species of freshwater goby, Rhinogobius mengyangensis sp. nov., is described from the upper Changjiang River basin in Sichuan Province, China, based on comparative morphology and molecular phylogeny. The new species is sister to Rhinogobius szechuanensis Tchang, 1939 and can be distinguished from its congeners by the following combination of characters: absence of sensory canals and pores on head; cheeks and operculum without spots or stripes; second dorsal fin with 9–11 longitudinal rows of inverted V-shaped or dash-like brown markings; incomplete brownish edges on flank scales below second dorsal fin; branchiostegal membrane bright yellow.
