Pilocrocis sororalis is a species of moth in the family Crambidae.

The forewings are semihyaline white with dark cupreous-brown markings.

The costal edge is pale ochreous, the markings not crossing it except the postmedial line.

There is a broad fascia across the discocellular space and the postmedial line is narrow and followed by a narrow white line.

The rest of the inner margin to the tornus is broadly shaded by dark and there is a large terminal dark space.
