A new species of Allobathynella (Crustacea, Bathynellacea, Parabathynellidae) from the hyporheic zone of the Hangang River, South Korea

초록

Bathynellacea including the parabathynellid genus Allobathynella Morimoto & Miura, 1957 is commonly found across the subterranean environment. The genus Allobathynella is the most species-rich genus known in Korea, and it now contains 23 species and one subspecies from South Korea and Japan. In this paper, we described a new species ofAllobathynella from Danyang, South Korea. Allobathynella danyangensis sp. nov. can be distinguished from its congeners by the presence of five simple setae on the antennule, seven spines on the maxillule and 3-5-10-6 setal formula of the maxilla. We describe the new species with molecular diagnosis based on the mitochondrial c oxidase subunit 1, the mitochondrial 16S rDNA, and the nuclear 18S rDNA gene sequences and morphological study.
