Abstract
The trunk segments of podocopine ostracods, which have previously been regarded as having a non-segmented body, are comprehensively illustrated in some lineages for the first time. Descriptions are given of the trunk segmentation of representatives from eight podocopine families: Bairdiidae, Eucytheridae, Leptocytheridae, Cytheridae, Hemicytheridae, Cytheruridae, Loxoconchidae and Xestoleberididae. As observed in the family Leptocytheridae, the maximum number of segments in the Podocopina examined is 11. The boundary between the thorax and abdomen of Podocopina is not distinct. It was found that in Podocopina, the paired copulatory organs are derived from between the fifth and seventh most terminal segments in females and the second most terminal segment in males. It is suggested that the female body plan of Podocopina is plesiomorphic because it is common to platycopid structure and approximately satisfies the supposed ground plan of the Maxillopoda.
