Euchaetis coccoscela is a moth in the Oecophoridae family. It was described by Turner in 1946. It is found in Australia, where it has been recorded from Western Australia. The wingspan is 25-28 mm. The forewings are pale grey with a crimson costal line and a fuscous-reddish basal dot on the dorsum, with another shortly above. There is an outwardly curved fuscous-purple line from one-fourth of the costa to two-fifths of the dorsum and a similar less distinct line from two-thirds of the costa to the tornus. The area between these lines is suffused with reddish and there is an irregular dark fuscous dentate line from two-thirds of the costa to the tornus, as well as a terminal line. The hindwings are pale grey.
