Type locality: "Florida Straits, 550 m, Silver Bay stat. 2483'" [ = 26°25.5"N 79°O1'W]. Male holotypein USNM no.139626; paratypes in USNM, RMNH.
Western Atlantic: Florida Straits and northwest of Anguilla.
Habitat and Biology:
Depth range between (393-) 451 and 550 m Substrate: mud.
Maximum total body length about 15 cm, carapace length 4 to 7 cm.
Interest to Fisheries:
Since so far only three specimens of this species are known, nothing concrete can be said about its fisheries potential. Its size is attractive, but the depth range and low abundance are negative factors.
