DIAGNOSIS. — Carapace a third wider than long, everywhere nodose with a drawing of ‘mask’ on anterior half. Three anterolateral lobes. Arm moderately bilobed on inner margin; wrist moderately nodose.

HABITAT. — In cavities of corals, rocks and sponges; on sand, shell, seagrass to mud bottom. Collected 1-20 m, reported 1- 60 m.

DISTRIBUTION. — Western Atlantic. Eastern Florida, Bahamas, Caiman, Cuba, Jamaica, Puerto Rico, Gulf of Mexico, Honduras, Panamá, Colombia, Venezuela, Brazil. Lesser Antilles VI ( St Thomas, St John, St Croix), ICA ( Anguilla, St Martin, St Barthélemy, Saba, St Eustatius, Barbuda, Antigua, Guadeloupe, Isla de Aves, Martinique, Barbados, Grenada, Tobago, Trinidad), IOV (Los Frailes, Margarita, Cubagua, Blanquilla, Tortuga, Los Roques, Bonaire, Curaçao).

REMARKS

This species can be confused with M. sculptus . The drawing of a ‘mask’ on anterior half of the carapace is a good character to recognize it. In addition Wagner (1990) indicates that there are three blunt anterolateral lobes in M. coryphe while M. sculptus has four.

DISTRIBUTION. — Western Atlantic. Bermudas, North and South Carolina, Florida, Bahamas, Cuba, Jamaica, Gulf of Mexico, Panamá, Colombia, Venezuela, French Guiana, Brazil. Lesser Antilles VI ( St Thomas), ICA (St Martin, Guadeloupe, Martinique*, Barbados, Tobago, Trinidad), IOV (Testigos, Los Frailes, Coche, Margarita, Cubagua, Tortuga, Los Roques, Bonaire, Curaçao, Aruba). * Martinique from unpublished fieldwork (coll. R. Ferry, Y. Buske, XI.2015, det. J. Poupin, specimen in BIOSPHERE collection, University of Fort de France).

REMARKS

This species was abundantly collected during KARUBENTHOS 2012. It can be easily recognized by acute anterolateral teeth.
