Spatial distribution of a dominant copepod species (ind m3) found off central-southern Chile in summer 2009. Abundance are mean values in the upper 0-200 m layer.

Nota: The upwelling region of central-southern Chile is located at mid latitudes within the eastern boundary upwelling region of Chile and Peru.
Loc:
sub-Antarct. (SE Pacif.), Beagle Channel, Magallanes region, Argentina (sub-Antarct.), Brazil (off Rio de Janeiro), Cape Horn, Straits of Magellan, SE Atlant., Chile (Puerto Otway, Concepcion, off Valparaiso, off Santiago), Indian (G. of Oman, Arabian Sea), Australia (New Wales South).

Type locality: 46°53'S, 75°11'W.
N: 27
Lg.:
(35) F: 2,6; (36) F: 2,37-2,08; M: 2,41-2,02; (47) F: 2,75-2,2; M: 2,3-2; (818) F: 2,2; M: 2; (849) F: 2,2; M: 2; {F: 2,08-2,75; M: 2,00-2,41}
Rem.: epi-? pelagic.
Sampling depth (sub-Antarct.) : 0-200 m.
This species could be a good indicator for the penetration of sub-antarctic waters into the NW Indian Ocean, if adult forms were captured there.
