Remarks. Macau specimens exhibit a total length of 6.0-6.5 mm and a maximum width of 2.0-2.5 mm. The species is nocturnal and attracted to artificial lights. In the past, it has been misidentified and confused with R. honesta ( Hua 2002 ; Chou 2004 , 2008 ; Yiu 2009 ), with consequent mix up of their respective distribution records ( Hua 2002 ; Lin and Yang 2019 ). According to Gressitt (1951) , Cucumis sativus is among its host plants and in Hong Kong larvae have been found boring into stems of Cucumis melo ( Yiu 2009 ). Figure 29.
