Phylomictis sarcinopa is a moth in the family Depressariidae. It was described by Edward Meyrick in 1920. It is found in Australia, where it has been recorded from Queensland.[1]
The wingspan is about 19 mm. The forewings are whitish irrorated grey with the plical and second discal stigmata represented by small pale flesh-colour spots accompanied by a few dark grey scales, a similar somewhat elongate spot in the disc midway between the plical and the base. The first discal stigma is represented by a longitudinal mark of blackish-grey irroration rather obliquely before the plical. There are two or three slight dashes of blackish-grey irroration towards the costa anteriorly, a very oblique series of short longitudinal similar marks tinged ochreous from beneath the costa before the middle to the second discal stigma, and a strongly curved subterminal series of similar marks. The hindwings are grey whitish.[2]
