Phylomictis maligna is a moth in the family Depressariidae.

It is found in Australia, where it has been recorded from Victoria.

The forewings are white, slightly ochreous tinged, with a thick irregular dark grey streak along the inner margin from the base to the anal angle and an irregular much interrupted dark fuscous transverse line from one-third of the costa to the dorsal streak beyond the middle.

There is a dark fuscous dot in the disc at two-thirds and the apical two-fifths of the wing are wholly fuscous, sprinkled with darker fuscous, and with a curved subterminal and hindmarginal series of obscure whitish marks.
