Abstract

A new genus and speciesSinorhodeus microlepis gen. et sp. nov., is described from a tributary of the Yangtze River, in Chongqing City, China. Sinorhodeus gen. nov. can be distinguished from four closely related genera, Paratanakia, Pseudorhodeus, Rhodeus, and Tanakia, by the following combination of characters: pharyngeal teeth 0,0,4–4,0,0, longitudinal scales 41–46, white spots on dorsal-fin rays absent, a black blotch on dorsal fin in juvenile absent, and less developed wing-like yolk sac projections in larvae. Phylogenetic analysis of one mitochondrial gene and six nuclear genes supports the establishment of the new genus.

Keywords: Pisces, Cyprinidae, Rhodeus, Tanakia, phylogeny, Yangtze River, China

终于发表了中国最艳丽的淡水鱼之一、鱊亚科新属新种——细鳞华鳑鲏 Sinorhodeus microlepis。本种为目前鱊亚科已知种中唯一咽齿为0,0,4-4,0,0、眶下感觉管为断线状、产卵于河蚬的特化物种,对于鱊亚科的物种演化等研究具有重要价值。
