Planche 1 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.
Planche 2 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).
Nota: endopod of P3 with lateral spine not extending as far as base of subterminal spine.
Planche 3 issued from : G.A. Heron in Antarct. Res. Ser. Washington, 1977, 26. [p.54, Fig.10, c-k]. Female (from SW Pacific-Antarctic area): c, habitus (lateral; scale bar: X); d, posterior of last prosomal segment and urosome (lateral; scale bar: X); e, urosome (dorsal; lacking caudal setae; scale bar: Y); f, left A1 (scale bar: Y); g, right A2 (scale bar: Y); h, labrum (scale bar: Z); i, left Md (scale bar Z); j, left Mx1 (scale bar: Z); k, right Mx2 (scale bar: Z).
Nota: Ratio of length genital segment to that of remainder of urosome 1.15: 1.
Planche 4 issued from : G.A. Heron in Antarct. Res. Ser. Washington, 1977, 26. [p.56, Fig.11, a-k]. Female: a, right Mxp (scale bar: Y); b-e, P1 to P4 (scale bar: Y); f, P5 (scale bar: Z).
Male: g, habitus (lateral; scale bar: X); h, posterior of last prosomal segment and urosome (lateral; scale bar: Y); i, urosome (dorsal; scale bar: Y); j, left Mxp (scale bar: Y); k, P5 (scale bar: Z).
Nota: P5 with a faint line of segmentation on ventral surface of some specimens; outer basal seta.
