Diagnosis. The species is similar to O. brevipalpis in the short labial palpi. However, O. atrisparsaria differs from O. brevipalpis in the following characters: the medial lines of both wings are deeper and broader than in O. brevipalpis ; the discal spot on the forewing is smaller than in O. brevipalpis . In the genitalia, O. atrisparsaria and O. brevipalpis differ from other congeners by the following characters: in the male genitalia, the apex of the valva is narrow and curved inwards; the costa of the valva has a short process; the saccular processes are absent; in the female genitalia, the lamella antevaginalis is not well developed; the signum is small; sternite 7 is weakly sclerotized on the posterior margin. The genitalia of O. atrisparsaria differ from O. brevipalpis in the following characters: the costal process of the valva of the male genitalia is much larger with a more rounded apex in O. atrisparsaria , while it is much smaller with a pointed apex in O. brevipalpis ; the lamella postvaginalis of the female genitalia is protrudes on the posterior margin, while it is flat in O. brevipalpis .

Distribution. China (Henan, Shaanxi, Gansu, Jiangsu, Shanghai, Zhejiang, Hubei, Jiangxi, Hunan, Fujian, Guangxi, Sichuan, Chongqing, Yunnan).

Remarks. The holotype was examined. We found some intraspecific variations in O. atrisparsaria : the colour of the wings varies from yellow (fig. 7) to yellowish brown (figs 5, 6); the colour of the transverse lines is usually yellowish brown (figs 5, 6), and sometimes pinkish red (fig. 7). These variationsall occur sympatrically in Zhejiang, China (figs 6, 7).

Discoglypha centrofasciaria ( Leech, 1897) in Xue (1992) was a misidentification of O. atrisparsaria . The wing patterns of D. centrofasciaria ( Leech, 1897) (Prout 1912–1916: pl. 5: f) are very similar to the paler form of O. atrisparsaria ; the only difference is that the discal spot of the hindwing is situated outside the medial line in D. centrofasciaria , but it passes across the discal spot in O. atrisparsaria . Prout (1934–1939) also suggested that D. centrofasciaria might be related to O. atrisparsaria . Thus, we suspect that D. centrofasciaria is potentially a senior synonym of O. atrisparsaria . Further morphological study is needed to confirm the systematic position of D. centrofasciaria .
