Distribution. China (Chongqing, Fujian, Guangdong, Guangxi, Hainan, Hong Kong, Hubei, Hunan, Jiangxi, Taiwan, Xizang, Yunnan, Zhejiang); India (Meghalaya); Japan (Honshu, Kyushu, Okinawa, Shikoku); Vanuatu.

Remarks. This is the most widely distributed species in this genus and can be distinguished by the spots on head, the markings on thorax, the wing marking patterns and the shape of male entoprocessus. Tsukaguchi (1995) also provided morphological characters of the third instar larva and biological notes of this species.
