| Abstract: | Differences between males and females in the morphology of the fifth legs were found in stage IV copepodites of Boeckella hamata and in stage V cope‐podites of B. hamata, B. propinqua, B. dilatata, B. triarticulata, and Calamoecia lucasi. There were also sexual differences in overall body size. In B. hamata, B. triarticulata, and B. dilatata, the differences were sufficiently obvious for stage V copepodites to be sexed at low magnifications. The diagnostic features of all stages are described. |
