Description. Head. Antenna about 2/5 length of forewing, bipectinate, tapering, length of longest ramus about eight and half times diameter of male antennal shaft, shortly bipectinate in female, length of longest ramus about three and half times diameter of female antennal shaft. Frons greyish white, rounded, not protruding, with pair of blackish brown dots medially. Labial palpus blackish brown, extending slightly beyond frons, second segment with greyish white hair-like scales. Vertex greyish green. Thorax. Dorsum greyish green. Patagium, tegula greyish green, blackish brown distally. Centre of tegula blackish brown. Posterior part of mesonotum with pair of black spots. Posterior margin of metanotum black. Two pairs hind tibia spurs in male, not dilated, without hair-pencil. Forewing: Length: male 26–27 mm; female 28–29 mm. Forewing outer margin weakly protruded, hindwing rounded. Wings greyish green, transverse lines blackish brown. Patterns of forewing: costa diffused with short longitudinal greyish brown flecks; antemedial, medial, postmedial, submarginal lines forming four black patches on costa; antemedial, medial lines indistinct; postmedial line weakly serrate, only distinct between costa and M1, near inner margin, appearing as spots on other veins, diffused with brown between postmedial, medial lines at inner margin; submarginal line appearing as series of small triangular patches between veins, distinct between M1 and M3, near costal, inner margins; terminal line appearing as series of short strips between veins; fringes greyish white mixed with greyish green; discal spot stellate, pale-centered, ringed blackish brown. Hindwing: with broad dark band between medial line and outer margin of discal spot, indistinct beyond cell; postmedial line serrate, indistinct, appearing as spots on veins, discal spot smaller than that of forewing; submarginal lines unbroken; terminal line, fringes similar to those of forewing. Venter greyish white to greyish brown; terminal bands of both wings broad, unbroken, paler towards outer margin; discal spot large and distinct; costa of forewing pale yellowish brown diffused with flecks. Abdomen. Pairs of black dorsal spots on first to sixth abdominal segments. Spots on first abdominal segment small, on second to sixth segments relatively large, closer together. First abdominal segment pale grey, other segments yellowish green. Setal patch absent on third sternite of male abdomen. Eighth sternite of male abdomen with irregularly shaped cleft, apical processes weakly sclerotized, not pointed. Male genitalia. Uncus square apically, length equal to basal width, with pair of long lateral processes, about one-fourth length of uncus. Gnathos with median process acutely pointed terminally, three-fourths length of uncus. Valva blunt terminally, about three times as long as basal width; costa sclerotized, slightly angled dorsally medially, expanded, bearing large area of long setae terminally; sacculus gently curved; sacculus with sclerotized band, broadened and serrate terminally, extending to base of ampulla. Ampulla broad, curved, with smooth margin, terminating with spur-like process. Saccus semicircular, about one-half length of basal width, with longitudinal arris apically in anterior half. Juxta with anterior margin concaved medially, length equal to basal width, terminal half triangular. Coremata developed. Aedeagus two-fifths weakly sclerotized posteriorly, with one tiny spine distally. Vesica without cornuti. Female genitalia. Ovipositor not strongly sclerotized, covered with dense setae. Lamella postvaginalis strongly sclerotized, curved posteriorly, with three lobes below, wrinkled anteriorly. Ductus bursae very long, about twice length of corpus bursae, not sclerotized; colliculum short, narrow. Corpus bursae small, rounded, membranous; signum large, rounded, with seventeen to nineteen marginal spines, several small asymmetrically distributed central teeth.

Diagnosis. The external characters of this species are similar to that of O. cordularia , but the rami of the male antennal are longer and the cleft of the eight sternite of the male abdomen is shallower. The most characteristic features of this species lie in the male genitalia: the uncus is square apically, but rounded in O. cordularia , the lateral processes of the uncus are longer than that of O. cordularia ; the dorsal margin of the sacculus is much broader, and the dorsal margin of the sacculus is not forming a spinous bar terminally; the ampulla is broader, and forming a big spur-like process, while in O. cordularia , it is triangular; the aedeagus has only one tiny spine, but has a pair of spines in O. cordularia . In the female genitalia: the ductus bursae is longer; the central teeth of the signum are fewer and unevenly distributed, which are radially distributed in O. cordularia .

Etymology. The specific name is from the Latin prefix long - and the word processus, which means long process. This refers to the lateral processes of the uncus.

Distribution. China (Jiangxi, Guangdong).
