Aptesis Forster 1850

Genus Aptesis Förster, 1850 Aptesis Förster, 1850: 82. Type species: Ichneumon sudeticus Gravenhorst, 1815 (= Ichneumon nigrocinctus Gravenhorst, 1815). Designated by Viereck (1914). Pezoporus Förster, 1869: 181. Type species: Ichneumon nigrocinctus Gravenhorst, 1815. Designated by Ashmead (1900). Name preoccupied. Clypeodiodon Aubert, 1968: 7. Type species: Aptesis (Clypeodiodon) flavifaciator Aubert, 1968. Monotypic. Four species, Ap. albibasalis (Uchida, 1930), Ap. albidipes (Walker, 1874), Ap. flavitrochanterus Watanabe & Taniwaki, 2018, and Ap. opaca (Cushman, 1937), have been recorded from Japan. Among them, Ap. albidipes is known only a single male holotype without apical part of antennae (Shimizu & Broad, 2020). In this study, I newly describe five new species below. Aptesis opaca (Cushman, 1937) is transferred from this genus to Oresbius. Aptesis sp. C sensu Watanabe & Taniwaki (2018) is not this genus (an undetermined genus of Phygadeuontinae). Aptesis sp. D sensu Watanabe & Taniwaki (2018) is Javra albotrochantellata sp. nov.
