Remarks.

In Macau, adults appear to be active only in late spring and range in total length 23-28 mm and 6.5-8 mm in maximum width. The species is exclusively nocturnal and readily attracted to artificial lights. The larvae apparently bore into lumber and a variety of trees, such as Machilus spp., Morus alba and oaks ( Yiu 2009). The species was introduced into Australia already in the 1960s ( Duffy 1963) and adult specimens emerging from wood furniture and other processed timber have recently been intercepted in several European countries ( Cocquempot et al. 2014).
