 |  |  |  |  |  |  |  |  |  | Ref.: |  |  |  | Heron, 1977 (p.51, figs.F,M); Heron & al., 1984 (p.465); Heron & Frost, 2000 (p.1038, figs.F, tab.2, 3) |  | |  issued from : G.A. Heron & B.W. Frost in  Proc. Biol. Soc. Washington, 2000, 113 (4). [p.1037, Fig.12, C-D]. Female (from NE Pacific): C, habitus (lateral; scale bar: w); D, pediger 4 posterior corner 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 . Nota: Ratio of length prosome to that of urosome 2.16:1.

  issued from : G.A. Heron & B.W. Frost in  Proc. Biol. Soc. Washington, 2000, 113 (4). [p.1021, Fig.1, H]. 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 for different Oncaea ' species).
