Remarks. So far, there were wide gaps between the records of P. oberthueri ( Vietnam, Taiwan of China, Ishigaki Island of Japan). The specimens from southeastern mainland China reported here fill the blank areas. The pronotum of the two examined female specimens are orange, with all margins narrowly darkened, thus these individuals should be regards as the nominotypical subspecies according to Kuijten (1992).

Natural History. Adults of two males were found hanging on bird capturing net.Another male and female were observed flying and captured by during daytime (observed by Jin-Teng Zhao). The larva feeds on decayed wood. The pupa is cradled in the inflated last larval skin ( Fig. 41 ).

Distribution. China (new record): Guangxi, Guangdong; Vietnam.
