Material examined. 132 (IN); 72 (M), 22 (F), 38 (OF), Bpot-Talude # MT 61, MOUFPE 15.206. 8 (IN); 1 (F), 7 (OF), Bpot-Talude # ARMT 62, MOUFPE 15.205. 26 (IN); 7 (M), 6 (F), 13 (OF), Bpot-Talude # ARMT 65, MOUFPE 15.204. 20 (IN); 3 (F), 17 (OF), Bpot-Talude # MT 65, MOUFPE 15.188. 36 (IN); 13 (M), 3 (F), 20 (OF), Bpot-Talude # MT 64, MOUFPE 15.191. 112 (IN); 74 (M), 8 (F), 30 (OF), Bpot-Talude # MT 65, MOUFPE 15.192.

Distribution. Western Atlantic: USA (east coast of Florida), Gulf of Mexico (Yucatan), northwest of Cuba, Caribbean Sea, south of Jamaica, Honduras, Nicaragua, off Guadeloupe, Dominica, Barbados, Brazil (Amapá, Pará, Maranhão, Ceará and Rio Grande do Norte – Potiguar Basin, Bahia) ( Holthuis, 1971; Ramos-Porto et al., 2000; Komai, 2004a; Felder et al., 2009; Vázquez-Bader and Gracia, 2013; this study).

Bathymetric distribution. Lemaitre (1984) recorded the species in the Bahamas, between depths of 446– 453 m, whilst Holthuis (1971) recorded the species between 256–692 m, similar to the depths reported by Pequegnat (1970) and Ramos-Porto et al. (2000). In the present study, the species was found between the depths of 389– 480 m.

Remarks. The material examined corresponds to the descriptions in Holthuis (1971) and Komai (2004a). Komai (2004a: 41) assumed the first record of this species from Brazilian waters based on material collected by the project REVIZEE Score Central off Bahia coast. This author pointed out that G. spinicauda has been cited on an unpublished conference abstract record by Ramos-Porto & Silva (2000). However, Komai (2004a) probably overlooked that Holthuis (1971) had already recorded this species in Brazil on the basis of eight ovigerous females collected at station of “Oregon” St. 2081 off the outfall of the Amazon River in the state of Pará. This record was cited by both Coelho and Ramos (1972) and Ramos-Porto and Coelho (1998). Also, Ramos-Porto et al. (2000; 2003) recorded this species in Amapá, Pará and Maranhão, based on the material collected by the project “REVIZEE/Pesca” in the northern region of Brazil. The present record is the first from the study area.

Females were more abundant and larger in size when compared to males (see Tab.2).
