Platymetopus quadrimaculatus Dejean, 1829

New record for Hong Kong. This is the first record of this distinctive species that was confirmed by D.W. Wrase from photo (pers. comm.). Material: 1 ex. W.T.L., 29.vi.08; 1 ex. W.T.L., 25.viii.13; 1 ex. W.T.L., 2.ix.10; sight record 1 ex. W.T.L., 9.ix.13. Biology: Imago found June to September. Can be attracted to light, it is fully winged and capable of flight.

Platymetopus tritus Bates, 1889

Listed by Schauberger (1933), Hua (2002), and Kataev et al. (2003) as occurring in Hong Kong. It maybe that this species is a junior synonym of P. flavilabris (Fabricius, 1798), from which it seems to differ in being smaller in size.
