Female (from NE Pacific): D, pediger 4 posterior corner and urosome (dorsal; scale bar: x). Male: E, pediger 3 posterior corner,pediger 4 and urosome (lateral; scale bar: x). Scale bars: 0.1 mm, see figures 3, 4, 5, 10 of Heron and Frost, 2000 for Oncaea canadensis and Oncaea insolita.

 issued from : G.A. Heron & B.W. Frost in Proc. Biol. Soc. Washington, 2000, 113 (4). [p.1022, Fig.2, L]. Female: P2-P4 endopod terminal ''spine set'' (combination of the lengths, shapes, and position of the three or two terminal spines on the endopods of swimming legs 2-4 , from left to right in figure, for different Oncaea' species). Nota: endopod of P2 with terminal spine length more than 3 times that of subterminal spine. Endopod of P4segment length about 2/3 that of terminal spine and about twice that of subterminal spine.

 issued from : G.A. Heron in Antarct. Res. Ser. Washington, 1977, 26. [p.79]. Nota: Swimming legs P2-P4 female with segmentation similar to that of Oncaea antarctica, but armature of terminal segment of endopods differs. Swimming legs male as in female except for modification of terminal armature of 3rd segment of 1st endopod.

(off Malte: 3000 m).
Sampling depth (Antarct., sub-Antarct.) : 0-1000-2000 m.
For Heron & al. (1984, p.479), the species resembles Oncaea ornata, but may be distinguished by differences in the relative lengths of the female urosome segments, the terminal endopod segments, and the spines of P2 and P4. | | | Last update : 27/01/2016 | |
| | | | According to Malt (1983b), who synonymized Oncaea ornata `form2´ sensu Boxshall, 1977 with O. englishi Heron, 1977, the species is also distributed in the NE Atlantic (Cape Verde Islands, Canary Islands, and at 40°N, 20°W), corresponding to your region 8 in the distribution map above.
