Remarks.

This species has been recorded only three times in Macau during the current census, in late spring and late summer. Adult activity is mainly during the hottest part of the day, when individuals promptly take off in flight when disturbed in the forest undergrowth, or display thanatosis if captured ( Yiu 2009; pers. obs.). The only specimen that could be measured had a total length of 13 mm and a maximum width of 4 mm. The host plants known so far in its wide distribution range include Aesculus chinensis , Bombax ceiba , B. malabaricum , Castanea mollissima , Ceiba pentandra , Excentrodendron hsiemmu , Melastoma candidum , Melia azedarach , Paulownia sp. and Quercus sp. ( Hua 2002; Yiu 2009; Lin and Yang 2019).
