Lophoptera tripartita

This species and the next are closely related, having similar facies with pale antemedials and postmedials crossing a rich brown forewing; there is a subapical yellow bar at the costa on the forewing underside (also seen more weakly in group B8). The pale fasciae are straighter, more oblique in tripartita and there is not a distinctly paler, yellowish patch between the reniform and the postmedial as in paranthyala. The genitalia of the two species are very similar in both sexes. The appendix bursae of the female is relatively weak, the post-ostial invagination and lateral lobes absent, though there is a slight transverse bar in the post-ostial position.

Geographical range. Sundaland, Sulawesi, Buru, New Guinea.

Habitat preference. The record of this species from Kinabalu (Holloway, 1976) is erroneous (see L. partitistis). It was taken infrequently in lower and upper montane forest on G. Mulu and also in alluvial forest in the lowlands at Long Pala during the Mulu survey. A singleton was taken at 1620m in upper montane forest on Bukit Retak, Brunei.
