Synonymised by Townes and Chiu (1970) . Comparative diagnosis. This species belongs to the incompleta species group sensu Townes and Chiu (1970) . This species can be distinguished from other species of this species group by the following combination of character states: face with moderate-sized punctures; propodeum with area superomedia partly (indistinctly) or completely separate from second lateral area (Fig. 4G ); mesoscutum medially with three continuous black spots and these spots sometimes united into a single large black area (Fig. 1G, H ); femur entirely yellow or sometimes with black areas (Fig. 5G, H ); ovipositor sheath 0.2-0.4 x length of hind tibia.

Japan (Honshu, Shikoku, Kyushu, Yakushima Is., Amamioshima Is., Tokunoshima Is., Okinawa Is., Ishigaki Is. and Iriomote Is.). Outside Japan, this species has been recorded from China, India, Malaysia, Philippines, Taiwan and Vietnam ( Yu et al. 2016 ). Bionomics. In Japan, adults were collected from April to November. In Tokunoshima Is., the first author collected this species along the edge of forest. Matsumoto and Sugimoto (1998) recorded a host, Nipponopsyche fuscescens Yazaki, 1926 ( Lepidoptera , Psychidae ), in Japan. In this study, we record the second host of this species, Manatha sp. ( Lepidoptera , Psychidae ). Remarks. This is the first record of this species from Ishigaki Is. and Iriomote Is. Townes and Chiu (1970) described the differences in body colouration between materials from Japan and other areas. We recognised these differences as intraspecific variations and concluded that Japanese population should be treated as X. naenia .
