Genus Apoclima Förster, 1869

Apoclima Förster, 1869: 171 . Type species: Apoclima signaticorne Förster, 1881 . Designated by Förster (1871).

In this study, I newly record this genus from Japan based on two new species, Apo. brevicauda sp. nov. and Apo. longicauda sp. nov., from Japan. Eastern Palearctic species can be distinguished by the following key.
