Cryptolechia hecate is a moth in the family Depressariidae. It was described by Arthur Gardiner Butler in 1883. It is found in Chile.[1]
The wingspan is about 17 mm. Adults are smoky black, the forewings above changing in certain lights to purplish. There is a reddish-cupreous curved marking at the end of the cell and there are a few scales of the same colour on the lower half of the dorsal margin, and a few more on the fringe towards the apex.[2]
