Phylomictis leucopelta is a moth in the family Depressariidae. It was described by Lower in 1902. It is found in Australia, where it has been recorded from South Australia. The wingspan is about 14 mm. The forewings are blackish-fuscous, with the extreme costal edge whitish, more pronounced in the middle. There is a large somewhat ovoid whitish basal patch, extending from the base to one-third, but not reaching the dorsum. Some faint whitish scales form two obscure parallel curved series. The hindwings are blackish.
