Erithyma trabeella is a moth in the family Depressariidae. It was described by Cajetan Felder, Rudolf Felder and Alois Friedrich Rogenhofer in 1875. It is found in Guyana, Brazil (Amazonas) and Peru.[1]
The wingspan is 10–11 mm. The forewings are black with metallic-green blotches on the dorsum about one-fourth and the middle, narrowed upwards and reaching small violet-white marks on the costa. An orange blotch occupies the costal half from the middle to near the apex, connected by a bar with the dorsum at two-thirds, enclosing blue-metallic longitudinal marks beneath the costa at the anterior angle, and in the disc obliquely beyond and beneath this, and with a violet-white dot preceding it in the middle. There is a rounded purple-coppery blotch extending over the termen and tornus. The hindwings are dark fuscous.[2]
