Lecithocera trigonopsis

Lecithocera trigonopsis is a moth in the Lecithoceridae family. It was described by Meyrick in 1907. It is found in the Himalayas.

The wingspan is 21-24 mm. The forewings are light fuscous or brownish, suffusedly mixed with whitish-ochreous and with a suffused dark fuscous spot on the base of the costa, as well as an elongate-triangular dark fuscous patch extending in the disc from near the base to one-third. There is an undefined dark fuscous dot beneath the costa just beyond this and a small triangular dark fuscous spot in the disc at three-fifths. A pale line, preceded by darker suffusion, is found from three-fourths of the costa to four-fifths of the dorsum, slightly indented above the middle. The hindwings are whitish-grey.
