A new cave-dwelling species, Triplophysa macrocephala sp. nov. is described based on specimens collected from a karst cave in Renguang village, Lihu Town, Nandan County, Guangxi Zhuang Autonomous Region, China. The new species can be distinguished from its congeners by possessing the following combination of characters: pectoral fin not reaching beyond pelvic-fin origin; caudal fin forked; body smooth or scaleless; dorsal-fin origin anterior to pelvic-fin origin, edge of dorsal fin truncate; dorsal fin with eight branched rays; anal fin with five branched rays; eye small and vestigial; lower jaw arched with a median notch; air-bladder wrapped in bony capsule, lateral enlarged, posterior chamber of air-bladder degenerated.
A new cave-dwelling fish, Triplophysa
anshuiensis, is described here based on specimens collected from a karst cave in Guangxi Zhuang Autonomous Region, China, interconnected with the Hongshui River system, a tributary of the Xijiang River in the Pearl River (Zhu Jiang) Drainage. The species can be distinguished from its congeners by a combination of morphological characters. A key to the cave-dwelling species of Triplophysa in the Xijiang River is provided.
Sinibotia lani, a new botiid loach is described from the Zuojiang River, located in Guangxi Autonomous Region, China. The species differs from other members of Sinibotia by a combination of the following morphological characters: body depth 17.5–21.1% SL; snout length shorter than postorbital length of head; eye diameter 10.2–13.2% HL; interorbital width 16.0–18.6% HL; suborbital spine reaching or extending beyond postorbital margin of eye; lower lip with pair of fleshy button-like clusters of papillae; dorsal-fin origin opposite to pelvic-fin origin, pelvic fin not reaching anus; includes six dark vertical bars on the body. A key to the species of Sinibotia is provided.
A new spined loach of the genus Cobitis Linnaeus is described from the Buquan River, located in Guangxi Zhuang Autonomous Region, China. The species differs from other members of Cobitis in China by a combination of morphological characters, none of them unique: body depth 14.3‒18.4% SL; lamina circularis long and knife-shaped; Gambetta zones present on the dorsolateral sides of the body (L1‒L5); 8‒11 large transverse elongated blotches on L5; 9‒12 large transverse elongated blotches on L1; maxillary barbels longer than eye diameter; 4‒5 narrow rows of dark spots on the caudal fin; caudal fin with 14 branched rays; a rectangular spot slightly smaller than eye diameter on the upper side of caudal fin base; and caudal-peduncle depth 79.5‒93.1% its length.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
