Taxonomic and Zoogeographic Notes on Japanese Orthocentrinae (Hymenoptera, Ichneumonidae), with Descriptions of Four New Species

Abstract

Nine genera and 22 species of Japanese Orthocentrinae were taxonomically and zoogeographically studied. The genus Apoclima Förster, 1869, and the subgenus Dicolus Förster, 1869 are newly recorded from Japan. Four new species, Apoclima brevicauda sp. nov., Apo. longicauda sp. nov., Hemiphanes japonicum sp. nov., and Proclitus tuberculatus sp. nov., were described. Eight species, Aniseres baikalensis Humala, 2007, H. gravator Förster, 1871, Megastylus (Dicolus) excubitor (Förster, 1871), M. (Dic.) impressor Schiødte, 1838, M.

In addition, the ten Japanese species were additionally recorded from several localities of Japan.
