VII. 1958, D. Townes leg. (MNHAH). Diagnosis. See Klopfstein (2014b). Distribution. Japan (Kunashiri Is.) (Klopfstein 2014a). Outside Japan, this species is widely distributed in Holarctic region (Yu et al. 2016). Bionomics. Host is unknown in Japan. Outside of Japan, Episyrphus balteatus (De Geer 1776) (Diptera, Syrphidae) has been recorded as a host (Hedwig 1958; Thirion 1994). Calybites phasianipennellus (Hubner 1813) and Lasiocampa quercus (Linnaeus 1758) (Lepidoptera, Lasiocampidae) have also been recorded as hosts (Morley 1906), but are considered doubtful records. Remarks. We could not find additional material from Japan.
