Kropp, Roy K., and Raymond B. Manning. The Atlantic Gall Crabs, Family Cryptochiridae (Crustacea: Decapoda: Brachyura). Smithsonian Contributions to Zoology, number 462, 21 pages, 10 figures, 1 table, 1987.-The Atlantic cryptochirids comprise four species in four different genera. One new species and three new genera are named. Troglocarcinus corallicola Verrill, 1908, shows an amphi-Atlantic distribution and is a generalist insofar as coral host is concerned. Pseudocryptochirus hypostegus Shaw and Hopkins, 1977, is assigned to a new genus, Opecarcinus, the only genus known in the Atlantic that also is represented in the Pacific. It ranges from the western Atlantic to Ascension Island and lives on agariciid and siderastreid corals. Troglocarcinus balssi Monod, 1956, is assigned to a new genus, Detocarcinus. It is restricted to the eastern Atlantic and lives on rhizangiid, oculinid, caryophyllid, and dendrophyllid corals. A new genus and species, Cecidocarcinus brychius, is named for specimens taken on dendrophyllid corals from the Valdivia Ridge, southeastern Atlantic, in 512 meters; it is the deepest occurring cryptochirid. OFFICIAL PUBLICATION DATA is handstamped in a limited number of initial copies and is recorded in the Institution's Annual Report, Smithsonian Year. SERIES COVER DESIGN: The coral Montastrea cavernosa (Linnaeus).
