Abstract

Members of Allobathynella Morimoto and Miura, 1957 and Hangangbathynella Park and Cho, 2013 belong to the family Parabathynellidae Noodt, 1965 exclusively inhabit subterranean environments including caves, springs, and interstitial groundwater. Among them, two parabathynellid species, Allobathynella cheongdoensis Park and Cho, 2016 and Hangangbathynella taechooni Park and Cho, 2013, have been reported in the hyporheic zones of the Nakdonggang and Namhangang Rivers in South Korea, respectively. To evaluate gene markers as diagnostic characters, we determined mitochondrial cytochrome c oxidase subunit 1 (CO1) and nuclear 18S rDNA from the topotypes of two Korean parabathynellid species, and then analyzed the genetic divergence among the two parabathynellids and their congeners. Additionally, we provided their habitus photographs and a brief discussion of the usefulness of the two marker regions for both genera as DNA barcodes.
