Lophoptera triobuncus sp. n.

Lophoptera trilobuncus

11-14mm. The forewing colour and patterning is somewhat intermediate between that of brunnistis and quadrinotata, but the species is distinguished by having hyaline areas at the base of the hindwing; the central zone of the forewing antemedial and postmedial is slightly paler, greyer than the ground, and is flanked by darker brown. The male genitalia have the uncus diagnostically trilobed, the central process acute, curved, spine-like, the lateral processes being setose lobes; the valves are setose ventrally, broadly quadrate dorsally. In the female genitalia the signum is set basally at one third in the bursa and is relatively small; the post-ostial invagination is weak, oblong, flanked by setose swellings that are elongately ovoid but constricted slightly centrally. L. abbreviata Walker from Australia is somewhat similar in facies and male genitalia but the valves are less quadrate costally and the uncus lacks lateral setose lobes.
