Imma dioptrias

Imma dioptrias is a moth in the family Immidae. It was described by Edward Meyrick in 1906.[1] It is found on New Guinea.

The wingspan is about 18 mm. The forewings are dark fuscous, the basal two-thirds suffused with violet blue. There are short yellowish subcostal and median streaks from the base, connected at the base, merged posteriorly in a broad transverse band of tawny-ochreous suffusion, limited by a narrow yellow fascia from before the middle of the costa to near the middle of the dorsum, not quite reaching it. A triangular pale yellow spot is found on the costa just before the apex, and a series of faint yellowish dots is located before the termen. The hindwings are transparent, with dark fuscous veins and a broad costal and narrower irregular terminal band. Both dark fuscous.[2]
