Description: Dorsal spines (total): 2; Dorsal soft rays (total): 6 - 7; Anal soft rays: 14 - 17. Nude without scale, complete lateral line extended until the end of the caudal fin. The bagrid catfish genus Tachysurus (known until very recently in the literature as Pelteobagrus or Pseudobagrus) is among the most speciose catfish groups in East Asia, with at least 31 valid species (Ng &Freyhof; Ng & Kottelat, 2007; Cheng et al., 2008). Are diagnosed by an extrascapular without a laterosensory canal, and a pterotic with a broad lateral laminar expansion (Mo, 1991). Habitat: Its members inhabit habitats ranging from fast-flowing hillstreams to large rivers. 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 virgatus: branched, probably referring to bluish black band along lateral line, “forked at the caudal base, [with] each branch reaching the tip [of the] caudal lobe”. Remarks: Still found in some online sources as Pseudobagrus virgatus but Eschmeyer's Catalog of Fishes has Tachysurus as the current genus name with Pseudobagrus virgatus as a junior synonym.
