Abstract
Two new species of Leptobotia are here described as L. rotundilobus from the Xin'an-Jiang of the upper Qiantang-Jiang basin in both Anhui and Zhejiang Provinces and the Cao'e-Jiang in Zhejiang Province, and L. paucipinna from the Qing-Jiang of the middle Chang-Jiang basin in Hubei Province, South China. Both have a plain brown body as found in L. bellacauda Bohlen & Šlechtová, 2016, L. microphthalma Fu & Ye, 1983, L. posterodorsalis Chen & Lan, 1992 and L. tientainensis (Wu, 1930). The two new species are distinct from these species in vertebral counts, further from L. posterodorsalis in vent placement and further from the other three species in pectoral-fin length. Both differ in caudal-fin coloration and shape, and dorsal-fin location and coloration, and also in internal morphology. Their validity is confirmed by their own monophyly recovered in a phylogenetic analysis based on the mitochondrial cyt b and COI genes.
本文描述了两种Leptobotia新种，分别是产于安徽和浙江钱塘江流域上游新安江和浙江曹娥江的L. rotundilobus，以及产于华南湖北长江流域中部清江的L. paucipinna。Bohlen & Šlechtová，2016；L. microphthalma Fu & Ye，1983；L. posterodorsalis Chen & Lan，1992 以及 L. tientainensis（Wu，1930）。这两个新物种在脊椎数上与上述物种不同，在排气孔位置上与 L. posterodorsalis 不同，在胸鳍长度上与其它三个物种不同。两者在尾鳍的颜色和形状、背鳍的位置和颜色以及内部形态上都有所不同。根据线粒体细胞 b 和 COI 基因进行的系统发育分析表明，这两种鱼的单系性证实了它们的有效性。
期刊介绍：
The Journal of Fish Biology is a leading international journal for scientists engaged in all aspects of fishes and fisheries research, both fresh water and marine. The journal publishes high-quality papers relevant to the central theme of fish biology and aims to bring together under one cover an overall picture of the research in progress and to provide international communication among researchers in many disciplines with a common interest in the biology of fish.
