Note.

The specimen reported here is the second specimen of this species after the holotype. In terms of body size, specimen collected in Vietnam are smaller than the holotype (this specimen with length of body 36.5 mm, forewing 19 mm and ovipositor sheath 46 mm; while the holotype with length of body 39.1 mm, forewing 21.3 mm and ovipositor sheath 59 mm). In addition, the new specimen was collected in November (holotype in May), thus we speculate the species may be at least bivoltine.
