Sinocyclocheilus donglanensis, a new cavefish (Teleostei: Cypriniformes) from Guangxi, China.Abstract
Sinocyclocheilus donglanensis, a new cyprinid species from a subterranean river in Donglan County in the Guangxi Zhuang Autonomous Region of southern China, is described. It is distinguished from all congeners by the following combination of characteristics: a completely scaled body with well-developed eyes; a curved lateral line possessing 57–64 scales; pectoral fin not reaching pelvic fin origin and last unbranched ray of the dorsal fin clearly serrated along its posterior edge; 8–9 predorsal vertebrae; 8–9 gill rakers; joints of dentary-angulars not close to each other at the isthmus; and a slightly inferior mouth with the upper jaw (6.2–7.4% in standard length: SL) protruding slightly beyond the lower one (5.7–6.7% SL). Sinocyclocheilus donglanensis is sympatric with the peculiarly shaped, hunchbacked S. altishoulderus.
