Distribution map of Lucicutia aurita by geographical zones
Loc:
? Antarct., South Africa (E), Sargasso Sea (off Cape Cod), W Indian, Indonesia-Malaysia, China Seas (South China Sea), E Taiwan, Japan (Sagami Bay), off Juan Fernandez Is., Chile ( N & S )
N: 11
Lg.:
(5) M: 8,4; (12) F: 8; (21) F: 8,7-7,3; M: 8,4-7,1; (26) M: 7,44; (70) F: 8,9; (866) F: 7,8-9,3; {F: 7,30-9,30; M: 7,10-8,40}
Rem.: Bathypelagic.
The presence of this species in the Sargasso Sea is surprising. For Harding (1974) in a vertical tow: 2000-1000 m.
According to Hülsemann (1966, p.705) the single strong spine-like protrusion on each side of the head, and the swollen basipodite 2 of the right P5 in the male are characters which separate L. aurita from L. maxima.
