Diagnosis. In fresh specimens, the shaft of the antenna is brown, and the rami are green. The male genitalia can be distinguished by the following combination of features: the large well sclerotized, triangular sacculus; the short and strongly sclerotized basal and subsaccular ridge; the small ampulla appearing as ridge; the absence of basal paired processes on the juxta. The aedeagus posteriorly bears two large lobes, one of them is the developed and acute cornutus, and the other is very broad and blunt, but forming a tiny point at apex. The eighth segment is a little similar to that of O. pervulgatus in that both tergite and sternite are concave and the latter has the long anterior lateral processes. The lateral processes on the tergite are tapered and pointed in O. falsaria but blunt and with a rounded tip in O. pervulgatus. The processes of the sternite are much shorter in O. falsaria compared to those of O. pervulgatus. The female genitalia (from Inoue 2005) have a band-like lamella antevaginalis, an extremely short ductus bursae, and a large wrinkled corpus bursae with more than ten strip-like sclerites mesally.
Distribution. China (Taiwan, Hainan, Yunnan), India, Bhutan, Sri Lanka, Malaysia, Indonesia.
