Kushia zosteraphila Harris and Iwasaki, 1996

Material examined. Pohang-si (35°57.351′N, 129°

Fig. 13

nule; D anten- 32.799′E), Korea; collected from shallow littoral by T Karanovic on 30 March 2013 .

Deposition. NIBRIV0000904518.

World distribution. Japan and Korea.

Diagnosis. Female 0.94 mm long. Posterior apex of urosome ( Fig. 14A) not pointed, reaching middle of caudal rami. Copulatory duct ( Fig. 14B) narrow. Caudal rami ( Fig. 14C) with narrow base and large outer protrusion in distal third. Third endopodal segment of third leg ( Fig. 14D) with two inner setae. Third endopodal segment of fourth leg ( Fig. 14E) with single inner seta. Fifth leg ( Fig. 14F) with strong first dorsal seta.

Remarks. Walker-Smith synonymized the genus Kushia with Porcellidium (2001). Porcellidium zosteraphila is very similar to P. gamoi ( Harris and Iwasaki, 1996) , which was reported from Korea by Kim and Kim (1997) and Lee et al. (2012), but the latter is a much larger species and has wider caudal rami, with a prominent lateral bump.
