Genus Oxyplax Hampson, 1893 Oxyplax Hampson, 1893, Fauna Br. India (Moths) 1: 372 (key), 376. Type species: Aphendala ochracea Moore, 1883, by original designation. Darna (Oxyplax): Holloway, 1986. Malay. Nat. J. 40 (1–2): 138. Note. The genus includes middle-sized moths with brownish ground color. The male antennae are bipectinate till to the tip; female antennae are filiform. The labial palpi are extended forward. The color of the forewing is variable, ranging from yellow or gold to dark brown, but there is always a pale or dark, obliqued postmedial line that runs from the apex to the inner margin at ca.1/2 distance from the wing base; the veins M 2 and M 3 are always far from each other, and the vein R 5 is not stalked with the vein R 3 +R 4. The vein Sc + R 1 of the hindwing is joined to the anterior margin of the discal cell at basal 1/3. The tibial spurs are 0-2-4. In the male genitalia, the uncus is bifid into two lateral processes; the gnathos is developed, stout, the former well-endowed with rows of dark scales; the subcostal in valva is always bearing a downwards, triangular process. The ductus bursae of female genitalia is straight; the corpus bursae lack signa.
