Ref.:
Bradford & Wells, 1983 (p.1, Descr.F, figs.F)
Species Xanthocalanus harpagatus - Plate 1 of morphological figuresissued from : J.M. Bradford & J. Wells in Polar Biol., 1983, 2. [p.2, Fig.1].
Female (from 82°22.5'S, 168°37.5'W): a-b, habitus (dorsal and lateral, respectively); c, rostrum; d, urosome (dorsal); e, genital segment (lateral); f, A1.

Nota: A1 24-segmented, extends almost to posterior border of metasome.

Nota: Posterolateral margins of metasome do not extend as faf as posterior border of genital segment, slightly asymmetrical, longer and pointed on left, shorter and round on right. Genital segment with patch of spines on right side. Anal segment very small. Caudal rami longer than wide.


Species Xanthocalanus harpagatus - Plate 2 of morphological figuresissued from : J.M. Bradford & J. Wells in Polar Biol., 1983, 2. [p.3, Fig.2].
Female: a, A2; b, Md; c, Md (masticatory edge); d, Mx1; e, Mx2; f, Mx2 (endopod with brush-like and worm-like filaments); g, Mxp; h-k, P1 to P4; l, left P5; m, right P5.

Nota: Mx2 1st lobe with 5 plumose setae, lobe 2 with 3 plumose setae, lobe 3 with 2 plumose setae (one very small) and 1 worm-like filament, lobe 4 with 1 large spinose spine and 2 plumose setae, lobe 5 with 1 large spinose spine and plumose seta and 2 worm-like filaments, endopod with 7 brush-like filaments (one of which is much shorter and wider than remainder) and 1 worm-like filament.
