中国属鱼类共有 7种 ,分布于云南南部和西南部的三大流域中。其中半线Daniointerruptus,红蚌D .kakhienensis,缺须D .apogon和珍珠D .albolineatus分布于伊洛瓦底江流域的大盈江和龙川江水系 ;布朗D .browni和掸邦D .shanensis分布于萨尔温江上游的怒江水系 ;金线D .chrysotaeniatus分布于湄公河上游的澜沧江水系。老挝D .laoensis和另一个体侧有纵斑的尚未命名的小尼鱼生活在老挝北部靠近中国边境的湄公河上游水域里 ,它们有可能分布到中国境内的澜沧江水系。本文对中国属鱼类的研究进行了回顾整理 ,指出麦氏是老挝的同物异名 ,而对老挝是否生活在澜沧江水系尚有存疑 ;认为布朗是有效种 ,分布于萨尔温江的怒江水系 ;确认红蚌的确存在于云南西部的大盈江水系 ;否定过去将怒江的布朗和大盈江的红蚌统一鉴定为只分布于喜马拉雅山南侧的恒河流域的等鳍D .aequipinnatus的做法。本文同时提供了中国属鱼类种的检索表 ,并对每一个种的分布和其鉴别特征进行了描述 There are 7 species of Chinese wild fish, distributed in the three major basins in southern and southwestern Yunnan. Among them, the semi-line Daniointerruptus, D. Kakhienensis, 缺D.apogon and 珠D .albolineatus are distributed in the river courses of Dayingjiang and Longchuanjiang in the Irrawaddy river basin; Brown D. Browni and Shannon-d .shanensis Distributed in the upper Salween River Nu River; gold thread  D. chrysotaeniatus located in the Mekong upstream of the Lancang River system. Lao D. Laoensis and another unnamed ichthyosaurs with longitudinal speckles on the lateral side of the body live in the upper reaches of the Mekong near the Chinese border in northern Laos. They may be distributed to the Lancang River in China. In this paper, we review the research on the genus Catfish in China, and point out that Metarhizium is the synonym of Laotianus, while it is doubtful whether it is in the Lancang River or not. Erjiang River; confirmed that the red mussel is indeed present in the Daying River system in western Yunnan; Negligence in the past identified as the only distribution in the Ganges basin to the south of the Himalayas The practice of the same fin  D. aequipinnatus. At the same time, this paper provides a search table of the species of the genus Mythus in China, and describes the distribution of each species and its distinguishing features
