Abstract

A new species of freshwater gammarid, , was collected from Somaemuldo Island, South Korea. This new species is morphologically characterised by the absence of calceoli in antenna 2, absence of anteroproximal setae on bases in pereopods 6 and 7, outer ramus in uropod 3 with plumose setae on both margins, and a small terminal article of the outer ramus, which is shorter than adjacent spines. A description of the new species and morphological differences from related species are provided in the text. The new species was also compared to related species using partial sequences of the mitochondrial cytochrome oxidase subunit I (COI) gene. Genetic distances of COI sequences between the new species and related species, consisting of 21.5-26.3% difference, support as a valid species. Additionally, a key to identifying species in South Korea is provided.

摘要

一种新的淡水钩虾物种， ，是从韩国索梅穆尔多岛采集到的。该新物种在形态上的特征为：第二触角无钙质体，第六和第七步足基部无前近端刚毛，第三尾足外肢两边缘均有羽状刚毛，且外肢的末端小节较小，短于相邻的刺。文中给出了该新物种的描述以及与相关物种的形态差异。还利用线粒体细胞色素氧化酶亚基I（COI）基因的部分序列将该新物种与相关物种进行了比较。新物种与相关物种之间COI序列的遗传距离差异为21.5 - 26.3%，支持 为一个有效物种。此外，还提供了韩国 物种的鉴定检索表。
