Comparative diagnosis.

This species belongs to the regina species group sensu Townes and Chiu (1970). This species can be distinguished from other species of the group by the following combination of character states: face with a low, sublateral, vertical ridge on each side; scutellum conical; front edge of notaulus with a sharp-edged transverse crest; median black mark on mesoscutum well separated from black mark in front of scutellum (Fig. 2C ); T II to IV each with a pair of black spots (Fig. 2C ); T III to V densely, coarsely punctate (Fig. 6E ); female without black spots on T VI (Fig. 2C ); ovipositor sheath 1.05-1.25 × length of hind tibia.

Distribution.

Japan (Kyushu, Nakanoshima Is., Amamioshima Is., Tokunoshima Is., Okinawa Is., Miyako Is. and Ishigaki Is.). Outside Japan, this species has been recorded from Bangladesh, China, France, India, Indonesia, Malaysia, Myanmar, Pakistan, Philippines, Singapore, Taiwan and Vietnam ( Yu et al. 2016).

Bionomics.

In Japan, adults were collected from April to August and October. Kusigemati (1976) recorded a host, Malacosoma neustria testaceum (Motschulsky, 1861) ( Lepidoptera, Lasiocampidae ) from Japan. Townes and Chiu (1970) also recorded two hosts, Dendrolimus punctatus (Walker, 1855) and D. spectabilis (Butler, 1877) ( Lepidoptera: Lasiocampidae ), based on the materials from Hong Kong and Taiwan.

Remarks.

This is the first record of this species from Kyushu, Kuchinoerabujima Is, Takarajima Is., Tokunoshima Is. and Miyako Is. We examined the voucher specimens of " X. japonica " used in Uchida (1956) and Kusigemati (1976) and confirmed that all of them are identified as this species.
