A new species of Hangangbathynella (Crustacea, Bathynellacea, Parabathynellidae) from South Korea

초록

A new parabathynellid bathynellacean species, Hangangbathynella mihoensis sp. nov., was found in the groundwater of the Geumgang River in South Korea. This is the first report of Hangangbathynella from a tributary of the Geumgang River. All previously-reported species were found in the Hangang River and the origins of the two rivers are distinct from each other. The new species can be distinguished from its congeners by the two-segmented mandibular palp and the absence of epipods on thoracopod II. In this study, we provide a description of the new species and an identification table for the genus Hangangbathynella. In addition, we obtained partial sequences of the mitochondrial cytochrome c oxidase subunit I gene for DNA barcoding.
