Coloane, Hác-Sá, crushed under street light, 5 May 2018, R Perissinotto & L Clennell; ibidem 10 May 2019, electrocuted inside UV mosquito trap of ablution block, R Perissinotto (IZCAS); ibidem 1 Jun 2020 outside ablution block, R Perissinotto.

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 .
