Psorosticha melanocrepida is a moth in the family Depressariidae. It was described by Clarke in 1962. It is found in Japan (Kyushu).[1]
The wingspan is 16–18 mm. The forewings are clay colour, with the base, a spot at the mid-costa and an oblique bar from the costa slightly before the apex all blackish-fuscous. There is an ill-defined oblique, blackish-fuscous streak in the cell, at about the middle of the wing with a spot of raised scales at the outer end. There is a series of minute blackish-fuscous spots arranged in an outwardly curved arc at the basal third and a series of four or five small blackish-fuscous spots around the termen. The remainder of the forewings is marked with scattered blackish-fuscous scales. The hindwings are greyish, basally shading to fuscous at the margins.
The larvae feed on Citrus unshiu.[2]
