白鱼属鱼类的系统发育(鲤形目:鲤科)

PHYLOGENY OF THE CYPRINID GENUS ANABARILIUS (PISCES: CYPRINIDAE)

白鱼属(Anabarilius Cockerell)是我国特有的鲤科鱼类,主要分布于云南东部、中部和四川南部。分布范围不大,但种的分化强烈。 Regan(1904,1908, 1918)最先报道四种白鱼,但均置于Barilius属。尔后,Cockerell(1923)以Barilius andersoni Regan为模式种建立白鱼属;Nichols(1927)、张孝威(1944)、易伯鲁、吴清江(1964)、刘振华、何纪昌(1983)先后记述了部分种和亚种。陈银瑞、褚新洛(1980)在系统整理的基础上,澄清了白鱼属属级分类上的混乱,记述了三新种和一新亚种。何纪昌、王重光(1984)用数值分类法探讨了白鱼属的分类,报道了二新种和一新亚种。至此,白鱼属共包括15个种和亚种。

The principles and methods of cladistics are first applied to the study of the phylogenetic relationships within the genus Anabarilius. A detailed comparison was made between characters of Anabarilius as one side and Hemiculterella, Pseudohemiculter and Hemiculter as the other side. There are five synapomorphies in Anabarilius so that it is a monophyly. Hemiculterella sauvagei is considered as the out-group of Anabarilius for comparion, as H. sauvagei is closely related to and is more primitive than Anabarilius. Based on analysis of thirty-eight characters, the phylogenetic cladogram of Anabarilius is constructed. It is proposed that the dichotomy of the first sister group is correlated with the separation of Jin-sha and Nan-pan drainages. Nan-pan clade of the first sister group contains more plesiomorphies than Jin-sha clade and vice versa the case of apomorphies. Consequently Anabarilius is probably originated from the area of Nan-pan drainage, i. e. the eastern Yunnan of China.
