Remarks.

The size of this species in Macau ranges 18-23 mm in total length and 5-7 mm in maximum width. In the Macau SAR, this species is very scarce and has only been recorded in late spring and always in the Hác-Sá area of Coloane. Like in all Vesperidae, the larvae are presumably subterranean, feeding on root sapwood and pupating within the soil ( Švácha and Lawrence 2014). According to Hua (2002), host plants for the species include Citrus and Saccharum sinensis .
