Diagnosis : Carapace with rostrum short reaching 1/4 of scaphocerite length, unarmed; antennal and branchiostegal spine present, but not prominent; branchiostegal spine without distinct carina. Abdomen not dorsally carinate on all somites; somites 3 and 4 with posteromesial tooth, the one of somite 3 distinctly strong. Telson overreaching mesial branch of uropod, row of dorsolateral spines submarginal, between 22–27 pairs (modified from Cardoso & Young 2005 ). FIGURE 13 . Ephyrina benedicti Smith, 1885 . A. Female, lateral view. B. Telson, dorsal view. C. Abdomen, with somites 1–6 in dorsal view. (MOUPE: 19.417). Scale bar = 1 cm. Distribution : Western Atlantic: South Greenland , United States , Gulf of Mexico , Brazil ( Seamounts ( Ceará Chain) , Bahia , Espírito Santo ). Eastern Atlantic: south-west Ireland , Portugal (Canary Archipelago), Gabon , Saint Tomé Island. Indo-Pacific Oceans: northeastern Philippine Sea, Indonesia , west of Bonin Islands, Japan , Hawaii ( Crosnier & Forest 1967 ; Chace 1986 ; Crosnier 1987; Cardoso & Young 2005 ; Pequegnat & Wicksten 2006 ) ( Fig.14 ). Bathymetric distribution : 300–5000 m depth ( Crosnier & Forest 1973 ; Chace 1986 ; Cardoso & Young 2005 ; Burghart et al . 2007 ; 2017), herein this species was found in Ceará Chain at depth of 1030 m . Remarks : According to Crosnier & Forest (1973) and Cardoso & Young (2005) , the closest species of Ephyrina benedicti is E. bifida Stephensen, 1923 , but these species differ from each other in the following way (character of E. bifida in parentheses): abdominal somite 3 with a simple dorsal tooth ( Fig. 13B ) ( vs abdominal somite 3 present a bifid dorsal tooth); telson with 22–27 dorsolateral spines ( Fig. 13C ) ( vs telson with 4–7 dorsolateral spines). Ephyrina benedicti has a cosmopolitan distribution, but despite its wide occurrence in all oceans ( Fig. 14 ), few records were made in Western Atlantic, especially in Southwest Atlantic, being the first report of genus from Bra- zilian waters made by Cardoso & Young (2005) , with specimens collected in Campos Basin in States of Bahia and Espírito Santo . We provide herein the second report of the species E. benedicti in Brazilian waters highlighting the first observation in seamounts located in Northwestern Brazil .
