MATERIAL EXAMINED

CAMBODIA: 4♂♂, 12♀♀ : Mondulkiri Province, Keo Seima Wildlife Sanctuary, near O Pam station, 12°11’39”N 107°01’01”E, 14–24.XI.2018, leg. J. Constant, I.G.: 33.919 (3♂♂, 10♀♀: RBINS; 1♂, 2♀♀: RUPP) .

NOTE. The species was described from Ma Da, Dong Nai Province in South Vietnam ( CONSTANT & PHAM, 2011) and later recorded from Cat Tien National Park, Dong Nai Province by GNEZDILOV (2013), very close to the type location. Gnezdilov collected 4 specimens from plants of the undergrowth in the forest. The specimens collected in KSWS

15 represent the first record of the species in Cambodia and were found in similar habitat. The species was also present in a location where the forest was cleared by illegal logging.

The series of specimens from Cambodia provides information about the intraspecific colour variation, which actually ranges from nearly entirely stramineous specimens to nearly entirely black ones, with the typical horseshoe-shaped marking on the tegmina missing or weak in the extreme pale and dark forms ( Fig. 7 ).
