Relevant Information:

Described from specimens collected from the Zhujiang (Pearl River) basin, southern China. It closely resembles Tachysurus adiposalis and Tachysurus ussuriensis, 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). The Pelteobagrus genera have in the past been distinguished by their forked caudal fins (vs. truncate/emarginate caudal fins in Pseudobagrus but most of these genera have now been moved to a new family, Tachysurus (Bogutskaya et al. 2008). Habitat: Inhabits medium to large rivers in lowland areas with rocky substrate and moderate or fast current. Etymology: The genus name of Tachysurus: tachys, swift; oura, tail, referring to the presumed agility of T. sinensis based on its “long and nimble” tail (translation). The specific name of gracilis: graceful; slender. Remarks: Still found in some online sources as Pseudobagrus gracilis.
