A new species of Pseudobagrus (Teleostei: Siluriformes: Bagridae) from southern China

A new species of bagrid catfish, Pseudobagrus gracilis, is described from specimens collected from the Zhujiang ( Pearl River) basin, southern China. It closely resembles P. adiposalis Oshima and P. ussuriensis (Dybowski), but differs in having a large elliptical eye (19.8 - 24.4% HL), a short maxillary barbel not reaching the posterior margin of the eye, a lightly serrated posterior edge on the second dorsal spine, a caudal fin slightly emarginated with upper lobe slighter longer than lower lobe, frontal concave with a smooth surface, and supraoccipital process short ( far from the first basal bone of the dorsal spine).
