Abstract

Parabathynellidae is a family well known for its diversity and is endemic to the interstitial hyporheic zone of South Korea. Two new parabathynellid species, Nipponbathynella yeongchunensis sp. nov. and N. gapcheonensis sp. nov., were found through groundwater sampling on riverbanks in South Korea. Nipponbathynella yeongchunensis sp. nov. can be distinguished from its congeners by the base socket of the two dorsal setae on the antennule’s first segment. Nipponbathynella gapcheonensis sp. nov. can be distinguished by the protopod of thoracopod II–IV with hairs. We provide morphological descriptions and remarks about the two new species with molecular information based on 18S rRNA and partial COI gene sequences. In addition, phylogenetic analysis, including Nipponbathynella Schminke, 1973, which had not been previously molecularly evaluated, was inferred. The results of the 18S rRNA gene phylogeny suggest a close relationship between the genera Nipponbathynella and Arisubathynella, as well as Europe–North American genera. We have also included a brief discussion and an identification key for the five known parabathynellid genera found in South Korea.

1973年韩国Nipponbathynella Schminke二新种——兼论韩国副bathynelllid属(甲壳纲，bathynellae)

副蕨科是一个以其多样性而闻名的家族，是韩国间质性下丘脑区的特有植物。通过对韩国江岸地下水取样，发现了两个新的副水蛭属物种Nipponbathynella yeongchunensis sp. 11和n.g apcheonensis sp. nov。永春Nipponbathynella sp. 11 .可以通过其触角第一节上的两个背毛的基窝来区分其同族。日本海螺(Nipponbathynella gapcheonensis sp. 11 .)的原始足类为胸足类II-IV类，有毛。基于18S rRNA和部分COI基因序列的分子信息，对这两个新种进行了形态描述和评价。此外，还进行了系统发育分析，包括Nipponbathynella Schminke, 1973，此前未进行分子评价。18S rRNA基因的系统发育结果表明，日本海棠属和日本海棠属以及欧洲-北美海棠属之间存在密切的亲缘关系。我们还包括了一个简短的讨论和鉴定密钥的五个已知的在韩国发现的副蕨属。

期刊介绍： Diversity (ISSN 1424-2818) is an international and interdisciplinary journal of science concerning diversity concept and application, diversity assessment and diversity preservation. It is focused on organismic and molecular diversity. It publishes reviews, regular research papers and short notes in the regular issues. Related news and announcements are also published. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. Full experimental details must be provided so that the results can be reproduced.
