Aperileptus Förster, 1869: 109. Type species: Plectiscus albipalpus Gravenhorst, 1829. Designated by Förster (1871).
Three species, Ape. albipalpus (Gravenhorst, 1829), Ape. obscurus Humala, 2007, and Ape. vanus, have been recorded from Japan (Dasch, 1992; Kasparyan et al., 2012). In this study, I record some distribution data of Ape. albipalpus and Ape. vanus. The identification of males of this genus is difficult except for Ape. vanus, thus the male of Ape. albipalpus was not treated in this study.
