03C587DEFFA3763DFC7AF92B279EBDD1.taxon	discussion	Remarks. Oshoroclausia shares a biramous leg 4 with Likroclausia, Pontoclausia, and Rhodinicola (see Băcescu and Pór 1959; Ho and Kim 2003; Kim et al. 2013). Likroclausia clearly differs from Oshoroclausia in its cyclopiform body bearing a pair of antler-like lateral processes on the tergites of the second to fourth pedigerous somites (see Kim et al. 2013) (vs an elongate body without lateral processes on the tergites of the pedigerous somites). Pontoclausia can be distinguished from the new genus by the following combination of characters: its distinctly segmented cyclopiform body, 4 - segmented antenna, 3 - segmented rami on legs 1 to 4, and leg 5 with a free protopod (see Băcescu and Pór 1959) (vs elongate body lacking distinct segmentation between first pedigerous and anal somites, 2 - segmented antenna, 2 - segmented rami on legs 1 to 4, and protopod of leg 5 fused to fifth pedigerous somite). Rhodinicola is very similar to the new genus but can be distinguished by the following characters: elongate antenna 3 - or 4 - segmented with four terminal claws; swimming legs bearing inner coxal setae, and leg 5 bearing setae on anterior margin (see Levinsen 1878; Laubier 1970; Ho and Kim 2003; Björnberg and Radashevsky 2011; Kim et al. 2013) (vs antenna 2 - segmented, its peanut-shaped terminal segment with two terminal claws, legs 1 to 4 lacking inner coxal setae, and leg 5 without setae on anterior margin).	en	Uyeno, Daisuke, Kakui, Keiichi (2015): The First Record of a Species of Clausiidae (Copepoda: Cyclopoida) from Japanese Waters, with the Proposal of a New Genus.
