Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1992, 35 (4/5). [p.255, Fig.1, d-j]. Female: d, forehead (lateral); e, last thoracic segment and urosome (lateral left side); f, Mx1; g, P2; h, endopod of P3; i, endopod of P4; j, P5. Nota: Cephalosome and 1st metasomal segment separated, 4th and 5th separated. Prosome/urosome length ratio 81 : 19. Rostral filaments slender. A pair of large eyes. A1 extends beyond end of caudal ramus with 4 segments. Urosomal segments and caudal rami in the proportional lengths 42 : 21 : 16 : 4 : 17 = 100. Caudal rami with length/width ratio 2 : 3. A2 exopod a little longer than endopod (7 : 6). Mx2 endopod with 7 brushform and 1 vermiform sensory filaments.

| | | | Loc: | | | NW Pacif., Japan (Izu region), W Pacif. (off Philippines, Indonesia, Australia), San Diego, G. of Mexico, off Mauritania - NW Cape Verde Is. (in Lapernat, 2000) | | | | N: | 6 | | | | Lg.: | | | (143) F: 4,25; (225) F: 4; (867) F: 4,1-4,23; (911) F: 3,15-4,5; {F: 3,15-4,50} | | | | Rem.: | méso-bathypélagique.
Park (1983 a, p.321) doute de l'identification de Grice. Cependant il n’est pas exceptionnel d'observer un tel mode de répartition correspondant à une période antérieure à la fermeture de l'isthme de Panama.
Le mâle indiqué par Chihara & Murano (1997) est sans doute une erreur.
