[Ostracoda] The second segment of the endopodite of the second antennae thet carries five setae, the longest being the f-seta, with the h-, i- and j-setae being shorter, subequal, thin-walled and sensory. In males the second segment of the endopodite usually carries two short setae (c- and d-) near its base, and five much longer setae subterminally. At the base of the f-seta there is sometimes an extremely short stubby e-seta.
