Rectiostoma eusema explained

Rectiostoma eusema is a moth in the family Depressariidae. It was described by Lord Walsingham in 1914.[1] It is found in Guatemala.

The wingspan is about 12 mm. The forewings are bright yellow at the base, with a rosy purplish metallic spot on the costa, and a limbal shade in the yellow basal patch, which is bounded at about one-fourth by a dark reddish cupreous line, descending straight from the costa to the dorsum, its outer side shining rosy steel grey, succeeded by a band of rich cupreous, on the outer edge of which about the middle, is a conspicuous tuft of raised dark brownish fuscous scales; the median portion of the wing, except for a cupreous patch, on the costa rather beyond the middle, is shining rosy steel, blending into a cupreous patch, produced to the apex and containing some black and bright blue-metallic scales in its upper portion, and a strong patch of brilliant purple before the termen. The hindwings are shining, dark brownishcupreous.[2]
