Description

Morphology

The abdomen is twisted, as the species lives in snail shells. The right cheliped is larger than left, minor cheliped, which has a rounded dorsal surface. The dactyls of the walking legs are straight. The merus of the major cheliped has one or two prominent tubercules. The legs are not banded, but in life the antennae are orange and the body is a uniform dark green, stippled with blue or white granulations.
