Diagnosis: Integument firm. Rostrum not reaching beyond antennular peduncle, 10–14 dorsal teeth and with a single tooth on lower margin. Carapace not dorsally carinate posteriorly. Branchiostegal spine supported by a carina that extends back to posterior part of branchial region. Abdomen carinate on all but the first somite and with a median posterior spine on the third, fourth, fifth and sixth somites; telson dorsally sulcate on proximal half and armed with 6–15 dorsolateral spines (modified from Chace 1940).
Distribution: Western Atlantic: United States (Oregon), Bermudas, Bahamas, Gulf of Mexico, Caribbean Sea, Antilhas, Panama Basin, British Guiana and Brazil (Pará, Rocas Atoll, Fernando de Noronha and off Pernambuco). East Atlantic: Portugal (Madeira Island). Indo-Pacific Oceans: East coast of Africa, Aldabra Atoll, Arabian Sea, Maldives Islands, Gulf of Bengale, Andaman sea, United States (Northward California, coast of Baja) and Peru (Springer & Bullis 1956; Crosnier & Forest 1973; Chace 1986) (Fig. 4).
Bathymetric distribution: 550–5900 m depth (Springer & Bullis 1956; Crosnier & Forest 1973; Burghart et al. 2007; 2017), herein this species was found in Rocas Atoll at depths between 65–850 m, thus extending its bathymetric distribution from shallow waters.
