 issued from : G.D. Grice & K. Huisemann in Proc. U.S. natn. Mus., 1967, 122 (3583). [p.51, Figs.56-59]. As .
Male (from Indian Ocean): 56, 5th thoracic segment and urosome (dorsal); 57, forehead (lateral); 58, idem (ventral); 59, P5.
|
 issued from : C.O. Esterly in Univ. Calif. Publs Zool., 1911, 6 (14). [Pl.26, Fig.3]. Female (from San Diego Region): 3, habitus (lateral) (urosome incomplete). Nota: Spine of the forehead is long and directed forward and slightly downward. A1 twice the length of the body. The length of the cephalothorax from the tip of the cephalic spine to the tip of the thoracic spine is over 5 times the length of the urosome.
|
 issued from : C.O. Esterly in Univ. Calif. Publs Zool., 1911, 6 (14). [Pl.28, Figs.38, 43]. Female: 38, part of last thoracic segment and urosome (lateral); 43, forehead (lateral). Nota: Rostrum short and rounded. Spines on the sides of the last thoracic segment are long and extend beyond the middle of the genital segment.
|
 issued from : C.O. Esterly in Univ. Calif. Publs Zool., 1911, 6 (14). [Pl.30, Figs.73, 84]. Female: 73, 1st basal of P4 showing the row of spines; 84, 1st basal of posterior Mxp to show the lamella.

Ref.: | | | Hernandez-Trujillo, 1991 (1993) (tab.I); Yamaguchi & al., 2002 (p.1007, tab.1); Galbraith, 2009 (pers. comm.); Schnack-Schiel & al., 2010 (p.2064, Table 2: E Atlantic subtropical/tropical) | | | | NZ: | 8 | | | | | | | Loc: | | | SE Atlantic, Canaries, G. de Gascogne, G. du Mexique, Ecosse W, Vancouver Is., Californie, Fosses Izu-Bonin & Mariannes, Indien | | | | N: | 10 | | | | Lg.: | | | (7) M: 3,4; (37) F: 5,2-3,8; M: 3,55-3; (40) F: 4,24-3,72; M: 3,4-3; (59) F: 5,2; (143) F: 5,2; (199) M: 3,27-3,12; {F: 3,72-5,20; M: 3,00-3,55} | | | | Rem.: | Mesopelagic, bathypelagic. For Esterly (1911, p.318) this species resembles G. unicornis but is easily distinguished by the much greater length of A1 and the character of the spines on the basals of P4.
Certain locality records are doubtful because of Markhaseva's (1996) suspicion on the synonymy of this species with Gaetanus miles. | | | Last update : 03/03/2011 | |
