Morphology and Systematics of the ostracod Euconchoecia (Myodocopa: Halocyprididae) from the North-Western Pacific

The North-Wesern Pacific species Euconchoecia pacifica is redescribed, and the status of currently known members of the genus reviewed. This review suggests that the genus includes 21 species. Nine of these have been previously described in the literature, two more were originally described as subspecies, but herein are raised to full specific rank. It is also evident from the literature that at least a further seven species have been miss-attributed to the known species. These latter ten species have only been partially described, and so have been left in open nomenclature. For the North-Western Pacific 14 species of the genus Euconchoecia are noted. A key to all these species is presented.
