Remarks.

In Macau, adults are active from early spring till mid-autumn and range in total length 11-15 mm and 4-6 mm in maximum width. The species is mainly nocturnal and promptly attracted to artificial lights. In Hong Kong, larvae of this species bore into wood of Morus alba (Yiu 2009). Elsewhere, larval host plants include also Albizia julibrissin, Celtis sinensis, Ficus pumila, Machilus thunbergii, Pinus massoniana and Prunus persica (Hua 2002; Lim et al. 2014).
