Description
Size: 2-7.3 mm

Color: When alive the color of the body is dull. Black transverse bands are seen on the walking legs and on the eyestalk. In formalin preserved specimens the carapace and the pereiopods appear red in color.

Eyestalks stout, reaching the middle third of the last segment of the antennular peduncles. Rostrum slender, shorter than ophthalmic scales. Antennal peduncles slightly shorter than antennular peduncles. Antennal acicle straight, barely reaching the base of the terminal joint of the peduncle. Left cheliped stouter and vastly larger than the right, about two and half times the length of the carapace. Segments granulous, more finely on hand. Carpus longer than merus and palm. Palm one and half times as long as broad, its outer surface longitudinally carinated near the middle line, the carina gradually fading away before it reached the finger cleft. The fixed finger deflexed, dactylus less than half the length of palm.

Found to occupy the shells of Cerithidea fluviatilis and Umbonium vestiarium, it can be easily located due to its lop sided movements.
