Comparative diagnosis.

This species belongs to the citrina 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: stigma light brown; area superomedia receiving lateral section of anterior transverse carina behind the centre (Fig. 4B ); ovipositor sheath 0.55-0.65 × length of hind tibia.

Distribution.

Japan (Ishigaki Is., Iriomote Is. and Yonaguni Is.). Outside Japan, this species has been recorded from Australia, Bangladesh, China, India, Indonesia, Laos, Malaysia, Nepal, New Caledonia, Pakistan, Palau, Papua New Guinea, Philippines, Solomon Islands, Sri Lanka, Taiwan, Truk Islands, Vanuatu and Vietnam ( Yu et al. 2016).

Bionomics.

In Japan, adults were collected in January, March, May and from October to December. Townes and Chiu (1970) noted that the greatest number of this species were collected from November to February (the cooler months) in Taiwan and this trend is also recognisable in Japan. In Iriomote Is., the first author collected this species in the meadows around paddy fields. The host is unknown in Japan whereas some lepidopterous pests have been recorded as hosts in Taiwan ( Sonan 1944).

Remarks.

In Japan, distribution of this species is restricted in Yaeyama Islands of Ryukyus.
