摘要
高原鳅属鱼类广泛分布于青藏高原及其周边地区,迄今已记录有123种,我国分布有105种,其中半数以上(58种)是近20年内相继发表的新种。该属的一些用于物种鉴定的形态学性状随栖息环境或鱼体生长变异较大,大量新种描述后缺乏系统比较和分类整理。本文总结了我国高原鳅属鱼类的种类和分布、分类研究历史、现状及存在的主要问题,并对今后的系统分类进行展望。
The genus Triplophysa is a species-rich group of nemacheiline loaches mainly distributed in the Qinghai-Tibetan Plateau and its adjacent regions. It includes approximately 123 currently identified species, 105 of which are so far known from China. During the past two decades, roughly 58 new species of Triplophysa have been described. However, some morphological characteristics usually used for species delimitation are closely size-associated or vary with the environment a given species lives. In addition, not enough comparisons with previously described species were made when they were described as new to science. In this paper, we try to provide an overview of the number of Chinese species and their distributions, history and status of taxonomy, problems in the taxonomy of Triplophysa, and give some suggestions for taxonomic revisions in the future.
