Remarks.

In Macau, adults of this species are active throughout the spring and are generally found in proximity to artificial lights at night. Their range in total length is 9-11 mm, and 1.5-3 in maximum width. In nearby Hong Kong, larvae of this species bore into Citrus spp. plants ( Yiu 2009). Other larval host plants include Diospyros kaki , Mallotus japonicas , Quercus acuta ( Lim et al. 2014), and in Japan even cultivated Prunus salicina ( Kusigemati 1985).
