FIGURE 3 . Acanthephyra curtirostris Wood-Mason & Alcock, 1891 . A. Ovigerous Female, lateral view. B. Telson, dorsal view (MOUFPE: 18.471). Scale bar = 1 cm. 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.
