Psittacastis molybdaspis is a moth in the family Depressariidae.

The forewings are brown with a yellow ochreous blotch on the base of the costa terminating beneath in a very oblique slender projection and including a short oblique brownish streak near its posterior edge.

A slender grey median streak, edged whitish beneath, is found from the base to two-fifths, then continued obliquely downwards but not reaching the dorsum.

There is also a very oblique rhomboidal blue leaden blotch from the costa before the middle, and an oblique-oval blotch between this and the tornus, as well as an orange-yellow very oblique wedge-shaped spot from the costa beyond the middle, marked with two white strigulae on the costa, the first emitting a blue-leaden line terminating in an elongate spot in the disc towards the termen.
