Diagnosis. The external characters of the species are similar to those of C. obvia , C. acuticornuta and C. rotundicornuta as follows: the outer margin of the hind wing forms a small protrusion at the end of M1; the forewing medial and postmedial lines protrude acutely outwards at M1; the submarginal lines of both wings are flanked by dark bands; the forewing submarginal line forms a black patch on the costa, which is more distinct on the underside of the wing. However, C. obliquata can be distinguished by the following characters: the rami of the antennae are much shorter than those of allied species, and the length of the longest ramus is shorter than the diameter of the antennal shaft; the protrusion of the forewing medial line of C. obliquata , C. acuticornuta and C. rotundicornuta is more distinct than that of C. obvia ; the band outside the submarginal line of the hind wing is far from the outer margin, but close to the outer margin in the other three species. In the male genitalia, the apical process of the uncus of C. obliquata , as in C. acuticornuta and C. rotundicornuta , is stouter than that of C. obvia ; the dorsal arm of the valva, as in acuticornuta and C. rotundicornuta , slightly protrudes outwards at the middle, while in C. obvia the protrusion is more distinct; the saccus of C. obliquata , C. obvia and C. acuticornuta is longer than that of C. rotundicornuta , and acute terminally; the apical cornutus is longer than that of C. acuticornuta ; the basal cornutus is shortly finger-shaped, and less strongly sclerotized, but narrow and long in C. obvia , stout and spine-like in C. acuticornuta , and short rod-like, strongly sclerotized with tiny distal spines in C. rotundicornuta . In the female genitalia, the lamella postvaginalis, as in C. acuticornuta and C. rotundicornuta , is semicircular, while in C. obvia , it is almost heart-shaped; the sclerotized part of the ductus bursae of C. obliquata , C. obvia and C. rotundicornuta is longer than that of C. acuticornuta .
