Type locality: "16-20 miles S. of Dry Tortugas, Florida (USA], 1065 m". Holotype in USNM, no. 136690; paratypes in USNM, UMML, RMNH, MCZ.
Western Atlantic from Florida (USA) to the Guianas, including the Caribbean Sea and the Lesser Antilles.
Habitat and Biology:
Deep sea between 655 and 1234 m, most catches between 800 and 1300 m; substrate sand or mud, sometimes with rubble.
Carapace length between 1.5 and 3.5 cm, corresponding with a total length of about 3 to 7.5 cm.
Interest to Fisheries:
So far none. The fact that the species is relatively small, usually taken singly or in pairs, and inhabits the deep sea, makes it not likely that it ever will be exploited commercially.
