Lophoptera triobuncus sp. n.
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.
