Heterodeltis trichroa

Heterodeltis trichroa is a moth in the Lecithoceridae family. It was described by Meyrick in 1906. It is found in Sri Lanka.

The wingspan is about 14 mm. The forewings are dark brown, with the basal third dark purple-fuscous. There is a triangular white blotch on the dorsum beyond one-fourth, reaching more than half across the wing and a cloudy ochreous-yellow dot on the costa before the middle, as well as a triangular ochreous-yellow patch extending along the costa from the middle to four-fifths, and reaching more than half across the wing. The hindwings are rather dark fuscous, in males with a subdorsal furrow throughout, filled with very long expansible pale fuscous hairs.
