Abstract
Both sexes of an ergasilid copepod, Limnoncaea diuncata Kokubo, 1914, are redescribed based on planktonic specimens collected from the type-locality in Hokkaido, Japan. Comparison of this species with Thersitina gasterostei (Pagenstecher, 1861) revealed that they are conspecific. Another ergasilid genus with two claws on the antenna, DiergasilusDo, 1981, is relegated to synonymy with Thersitina Norman, 1905. The diagnosis of Thersitina is amended.
