(NIBRIV0000753782) ( Fig. 4)

Synonymy. Euconchoecia chierchiae n. sp. - Muller (1890): p. 277, PI. 28, Figs. 1 -10.

For complete synonymy see Graves (2011).

Locality in Korea. South Korea, Jeju Island, Chuja Island , Station 5, 33°43.63 ʹ N 126°21.61 ʹ E .

Identifier. Ivana Karanovic

Diagnosis. Large ostracod, about 1.2 mm long ( Fig. 4). In lateral view elongated, and surface smooth. Ventral margin curved smoothly into posterior margin. Postero-dorsally both valves with a small spine. Anteriorly rostrum curves ventrally, pointed at the tip. Surface of the shell smooth.

Remarks. We identified the Korean species as E. cf. chierchie , because it is slightly slenderer than in the description provided by Graves (2011). According to the same authors, there seems to be a lot of morphological variability in E. chierchie , which may indicate several cryptic species.

Distribution. Distributed in all oceans between 40°N and 40°S.
