Abstract

Abstract A new species of gudgeon, Microphysogobio xianyouensis, is described from Mulan River in Fujian Province, southeastern China. M. xianyouensis appears to be closely related to M. brevirostris (Günther, 1868) of Taiwan. However, it can be well distinguished based on a combination of meristics, morphometric measurements, color pattern and molecular data. A molecular phylogenetic analysis of species of Microphysogobio from southeastern China and Taiwan based on concatenated mitochondrial Cyt b and D-loop genes is presented and tree topology strongly supports that M. xianyouensis as a distinct species and sister to M. brevirostris. Our molecular evidence agreed with Bănărescu's proposed taxonomic viewpoint, the tree topology reveals that the type species of the genus Huigobio, H. chenhsienensis, is nested within several valid species of Microphysogobio, and Huigobio is confirmed to be a junior synonym of the genus Microphysogobio.

福建微藻一新种(鲤形目:鲤科)及中国东南和台湾微藻种分子系统发育分析

摘要在福建木兰河发现了一新种——仙游微藻(Microphysogobio xianyouensis)。仙游M. xiyouensis与台湾的M. brevirostris (g nther, 1868)有亲缘关系。然而，它可以很好地区分基于组合，形态测量，颜色图案和分子数据。本文基于线粒体Cyt b和D-loop基因的序列对中国东南部和台湾地区的微藻生物物种进行了分子系统发育分析，树状拓扑结构有力地支持了M. xianyouensis是一个独特的物种，是M. brevirostris的姐妹物种。我们的分子证据与b nuricrescu提出的分类学观点一致，树的拓扑结构显示Huigobio属的模式种H. chensienensis嵌套在几个有效的微藻生物种中，并证实Huigobio属是微藻生物属的初级同义词。
