摘要

副水蛭科，水蛭水蛭。11月11日，在韩国一条小溪的一个隐蔽地带。新种在形态上与其同系物的区别在于下颌骨的门牙突上有5颗牙齿，雄性胸足动物VIII的齿叶上有4颗牙齿。物种描述以18S rRNA和部分CO1基因序列的形式补充了分子信息。此外，基于18S rRNA序列，推测了来自欧洲、美国、澳大利亚、印度、泰国、越南和韩国的15个副颌属的系统发育关系。来自韩国的ArisubathynellaPark & Eun(2012)、AllobathynellaMorimoto & Miura(1957)和EobathynellaBirstein & Ljovuschkin(1964)的成员属于两个独立的地理分支:Arisubathynella属于欧洲-北美分支，其他的属于东亚分支。

A new subterranean species of Arisubathynella Park & Eun, 2012 (Crustacea: Bathynellacea: Parabathynellidae) from South Korea, with remarks on the phylogenetic relationships among 15 parabathynellid genera

Parabathynellidae, Arisubathynella pocheonensis. sp. nov. from a hyporheic zone of a stream in South Korea. The new species is morphologically distinguished from its congeners by having five teeth on the incisor process in the mandible, and four teeth on the dentate lobe of male thoracopod VIII. The species description is supplemented with molecular information in the form of 18S rRNA and partial CO1 gene sequences. Additionally, the phylogenetic relationships among 15 parabathynellid genera from Europe, America, Australia, India, Thailand, Vietnam, and South Korea are inferred on the basis of 18S rRNA sequences. Members of ArisubathynellaPark & Eun, 2012, AllobathynellaMorimoto & Miura, 1957, and EobathynellaBirstein & Ljovuschkin, 1964 from South Korea belong to two separate geographical clades: Arisubathynella to the European-North American clade and the others to the East Asian clade.
