Abstract: A new cyprinid species from the He Jiang of the Zhu Jiang River (or Pearl River) basin in Guangxi, China is described here.Parasinilabeo longibarbus sp. nov.Holotype: IHB 2002051387, 4916 mm SL, from the He Jiang flowing to the Zhu Jiang River basin in Fuchuan County,Guangxi,China; collected by Lan Jia-Hu in April, 2002.Paratypes: IHB 2002051405-7, 2002051413, 2002051410, 2002051424) 5, 2001060469, 8 specimens, 4319) 5313 mm,same data as holotype.Count and morphometric data for the type material: D, iv, 8;A, iv. 5; P, i, 12-13; V, i, 8. Pharyngeal teeth in three rows,3.4.5-5.4.3; Perforated lateral line scales 37-40; scales above lateral line 5-6 and below 4.5-5; predorsal scales 14-17;circumpeduncular scales 16. Body depth 24.1-30.6(average 26.8) % SL, head length 22.0-24.8(23.7), length of caudalpeduncle14.1-17.6(15.6), depth of caudal peduncle 9.5-12.7(11.2), dorsa-fin length 17.8-23.2(19.9), pectoral-finlength 14.2-18.7(16.5), pelvic-fin length 13.6-18.2(15.4), anal-fin length 15.0-1911(16.7), predorsal length 50.6)53.3(52.4), prepectoral length 21.8-24.8(23.4), prepectoral length 52.8-57.7(55.7), and preanal length 74.1-79.9(77.7). Snout length 37.9-44.3(average 41.1) %HL, eye diameter 19.8- 3110(2312), and interorbital space 46.5-53.1(49.2).Diagnosis: P. longibarbus were distinguished from all other congeners by possessing a pair of wel-l developed maxillary bar-bels,scales on the breast and belly embedded beneath theskin, and a postlabial groove extended lateromedially to divide the lowerlip into two lateral lobes and one central part.The type specimens are deposited in theMuseumof AquaticOrganisms at the Institute of Hydrobiology,Chinese Academy ofSciences, Wuhan 430072,Hubei Province, China.
