Diathrausta ochrifuscalis is a moth in the family Crambidae.

The forewings are brownish ochreous, irrorated (sprinkled) with fuscous.

The costal and terminal areas are less strongly irrorated.

There are traces of a curved ochreous antemedial line, and ochreous discoidal lunule and three small spots on the costa towards the apex.

Both wings have traces of a pale sinuous subterminal line which is more distinct on the underside.
