Abstract The following nine ichneumonid species are recorded in Japan for the first time: Dusona carinifrons (Holmgren, 1860), D. chabarowski Hinz & Horstmann, 2004, D. rugifer (Förster, 1868) and D. viduator Hinz & Horstmann, 2004 (Campopleginae); Himerta sepulchralis (Holmgren, 1876) (Ctenopelmatinae); pictus Holmgren, 1858 and concitus Tolkanitz, 1994 (); Clistopyga sziladyi Kiss, 1959 (Pimplinae); and Phytodietus (Neuchorus) elongator Aubert, 1963 (Tryphoninae). Additionally, Dusona sachalini Hinz, 1985 (Campopleginae) and Excavarus sibiricola Kasparyan, 1990 (Tryphoninae) are newly recorded from the mainland of Japan.

Most of them usually attack larvae or Subfamily Campopleginae Förster, 1869 pupae of holometabolous insects (e.g., Gauld & Bolton, 1988). Dusona Cameron, 1901 Although it plays an important role in controlling terrestrial insect populations (e.g., Townes, 1969; Gauld, 1991; Quicke, This genus is one of the largest genera within Ichneumon- 2015), the faunistic information of them is not fully known. idae, which contains 442 species worldwide (Yu et al., 2016). In the present paper, we record some ichneumonid species Up to now, 82 species of the genus have been recorded in in Japan for the first time as the result of examinations of the Japan (Yu et al., 2016). Descriptions and a key to species of ichneumonid collections from Japan and its adjacent areas. the Eastern Palaearctic species were provided by Hinz and Horstmann (2004). We report five species of Dusona from Japan herein.
