Ecology and remarks.

This species occurs among sponges and coral rubble from 1– 20 m. Panamanian specimens agree closely with previous descriptions by Thomas and Klebba (2006) and White (2011) with the exception of coxa 4 having a smooth anterior margin and a slightly rounded posteroventral corner and a smooth ventral margin on epimeron 3. Living specimens are translucent pink in color with purple coloration on dorsal surface and red eyes.
