Diagnosis. The wing patterns of this species are similar to those of O. sinensium, but the postmedial lines on both wings are more deeply serrate and distinct, the areas inside the postmedial lines on both wings are diffused with blackish brown scales; a broad dark band is present between the medial line and the outer margin of the discal spot on the hindwing; the cleft of the eighth sternite of the male abdomen is shallower and the apical processes are less pointed and less strongly sclerotized. The most distinct differences between the two species are in the male genitalia and are as follows: irrorataria lacks the digitiform extension of the sacculus, present in sinensium and instead, in the former species, the dorsal margin of the sacculus is a sclerotized serrate band, and has spinulose terminal, extending to the base of the ampulla; the ampulla, present as a spinulose sclerotized bar in O. irrorataria, is absent in O. sinensium; the pair of sclerotized spines of the aedeagus are relatively smaller. In the female genitalia: the colliculum is shorter and narrower; the signum has more central teeth.

Remarks. The signum of the specimens from Ningxia, Sichuan and Yunnan (Fig. 95) are more rounded and smaller than those from Beijing, Gansu, Fujian, and Zhejiang (Fig. 94) but are otherwise similar. Thus, there appears to be variation in the shape of signum among O. irrorataria in different areas of China.
