Syn.: Oncaea schmitti : Malt, 1982 (p.190, figs.F)
Ref.:
Heron, 1977 (p.82, figs.F,M); Heron & al., 1984 (p.479, 488, Rem.F); Heron & Frost, 2000 (p.1057, tab.2, 3)
Species Epicalymma schmitti - Plate 1 of morphological figuresissued from : G.A. Heron in Antarct. Res. Ser. Washington, 1977, 26. [p.85, Fig.28].
Female (SW Pacific-Antarctic area): a, habitus (lateral (scale bar: X); b, posterior of last prosomal segment and urosome (lateral; scale bar: Y); c, urosome (dorsal; scale bar: Y); d, right A1 (scale bar: Y); e, left A2 (scale bar Y); f, labrum (scale bar Z); g, right Md (scale bar: Z); h, right Mx1 (scale bar: Z); i, left Mx2 (scale bar: Z); j, right Mxp (scale bar: Y); k-n, P1 to P4 (scale bar: Y).

Nota: Anal segment with operculum margin nearly straight. Urosome (lateral view) with caudal ramus width as wide at midpoint as that of anal segment (posterior to operculum).


Species Epicalymma schmitti - Plate 2 of morphological figuresissued from : G.A. Heron in Antarct. Res. Ser. Washington, 1977, 26. [p.84, Table 6].
Female: Armature of swimming legs P1-P4.
Si = inner seta; St = terminal seta; Se = outer seta. Arabic numerals: serae; Roman numerals = Spines.


Species Epicalymma schmitti - Plate 3 of morphological figuresissued from : G.A. Heron in Antarct. Res. Ser. Washington, 1977, 26. [p.87, Fig.29, a-e].
Male: a, habitus (lateral; scald bar: X); b, posterior of last prosomal segment and urosome (lateral; scale bar: Y); c, urosome (dorsal; scale bar: Y); d, left Mxp (scale bar: Y); e, P1 (basis and endopod).

Nota: Anal segment with operculum margin straight. Distal corner of last prosomal segment rounded. P5 terminal seta length about same length as that of lateral seta.

Records include previously published personal observations and data presented in this study (p.1023, Table 3).

Antarct. (Weddell Sea: pack-ice, SW Pacif. SW), off N Cape Verde Is., Arctic, Norwegian Sea, Station 'P', NE Pacif.

Rem.: bathypelagic, abyssopelagic.
Sampling depth (Antarct.) : 500-1000-2000 m.
For Heron & al. (1984, p.488), the only morphological differences that could be found between specimens from the North and South Polar areas were P2 endopod segments are partially fused on the anterior surface; leg segmentation is often obscure and slightly variable between specimens of a specis. The outer seta on P4 2nd basis is slightly longer on Arctic Ocean females.
