Abstract

A new loach species, is described from the Guangxi Zhuang Autonomous Region, China. The new species can be differentiated from other members of the genus by combinations of characters: a developed posterior chamber of the swim bladder, 13-14 branched caudal-fin rays, 8-16 lateral-line pores, body width 12-15% of standard length (SL), interorbital width 42-47% of head length (HL), and caudal peduncle length 11-16% of SL. Bayesian inference phylogenetic analysis based on mitochondrial Cyt provided strong support for validity of (uncorrected -distance 6.0-7.5%).

摘要

一种新的泥鳅物种在中国广西壮族自治区被描述。该新物种可通过以下特征组合与该属的其他成员区分开来：鳔后室发达，尾鳍分支鳍条13 - 14根，侧线孔8 - 16个，体宽为标准体长（SL）的12 - 15%，眶间距为头长（HL）的42 - 47%，尾柄长为SL的11 - 16%。基于线粒体Cyt的贝叶斯推断系统发育分析为该物种的有效性提供了有力支持（未校正距离为6.0 - 7.5%）。
