Scaphocalanus vervoorti Park, 1982 (F,M) | |
| | | | | | | Syn.: | Scaphocalanus subbrevicornis : Vervoort, 1951 (p.116, figs.F,M); 1957 (p.110, Rem.); Tanaka, 1960 (p.43, figs.F); Bradford, 1971 b (p.23, fig.83: F); Bradford & al., 1983 (p.101, figs.F,M);
Scolecithrix glacialis (M) : Wolfenden, 1911 (p.251) | | | | Ref.: | | | Park, 1982 (p.112, Descr.F,M, figs.F,M); Razouls, 1994 (p.125, figs.F, M, Rem.) |  issued from : T. Park in Biology of the Antarctic Seas XI, Antarct. Res. Ser, 1982, 34. [p.113, Fig.22]. Female: a, habitus (dorsal); b, idem (lateral left side); c, forehead (lateral); d, genital segment (lateral); e, last thoracic segment and urosome (dorsal); f, idem (lateral left side); g, A2; h, Md; i, Mx1. Nota: Urosome about 33/100 length of prosome. All cephalosomal appendages as in S. farrani except Mx1, which has 2 posterior spines, instead of 3, on 1st inner lobe and 6 setae, instead of 7, on exopod.

 issued from : T. Park in Biology of the Antarctic Seas XI, Antarct. Res. Ser, 1982, 34. [p.116, Fig.24]. Male: a, habitus (lateral right side); b, last thoracic segment including P5 and urosome (lateral right side); c, A2; d, Md; e, Mx1; f, Mx2; g, Mxp. Nota: Urosome about 50/100 length of prosome. All cephalosomal appendages similar to those of S. antarcticus except for some details of Mx1 and Mxp.

 issued from : W. Vervoort in Verh. K. ned. Akad. Wet., Afd. Natuurk., 1951, (Sect. 2) 47 (2). [p.117, Fig.62]. As Scaphocalanus subbrevicornis. Female (from 65°.5S, 10°58'W): a, left P2 (posterior); b, posterior part cephalothorax, right P5 and urosome (lateral). Nota: For Vervoort (1951, p.110), this species resembles S. brevicornis Sars, 1900 ; it is , however, smaller and the abdomen is comparatively longer. The outer edge spine on the distal segment of P5 is extremely small, and in some specimens it seems to be absent ; the apical spine on that segment is slightly longer than the segment and appears to be nude . The internal marginal spine is long and slightly curved towards the apex. The outer edge is haired and not, as in S. brevicornis, with fine teeth. Wolfenden, in his description of P2 of S. subbrevicornis, mentions spines on the 1st exopodal segment ; such spinules are not to be observed in his drawing of that appendage ; in Vervoort’s specimen the segment is nude. Along the outer edge of the endspine of P2 there are 26-26 obtuse teeth, very different from the acute teeth observed there in S. brevicornis.

 issued from : W. Vervoort in Verh. K. ned. Akad. Wet., Afd. Natuurk., 1951, (Sect. 2) 47 (2). [p.119, Fig.64]. As Scaphocalanus subbrevicornis. Male (from ± 66°.5S, 11°W): a, habitus (lateral); b, posterior part cephalothorax and urosome (lateral, left side); c, P5 (rt = right foot, lt = left foot).

 Issued from : J.M. Bradford in N.Z. Oceanogr. Inst., 1971, 206, Part 8, No 59. [p.22, Fig.83]. As Scaphocalanus subbrevicornis. Female (from Ross Sea): 83, P5. Scale bar: 100 µm.

 Issued from : O. Tanaka in Spec. Publs. Seto mar. biol. Lab., 10, 1960 [Pl. XIX, 1-4]. As Scaphocalanus subbrevicornis. Female (from 67°03.5'S, 40°50'E): 1, forehead (lateral); 2, last thoracic segment and abdomen (lateral); 3, P2 with 2 exopodal segments; 4, P5. Nota: Cephalothorax and abdomen in proportional lengts 74 to 26. Posterior thoracic margin triangularly produced but the apex obtusely rounded. Abdominal segments and caudal rami in proportional lengths 34 : 18 : 18 : 11 : 19 = 100.
Genital segment not swollen below.
Endopod of A2 slightly longer than the exopod (proportional lengths 50 to 47.
P1: exopod 3-segmented and endopod 1-segmented. The 2nd and 3rd exopodal segments furnished with groups of small spines on the posterior surface.
P2: Outer edge of the 1st exopodal segment shorter than that of the 2nd segment, their proportional lengths 7 to 10; they are nearly straight; the basis and the 1st exopodal segment furnished with spinules on the posterior surface. These spinules were also observed in P3, but not in P4.
P5 2-segmented. Distal segment with an apical spine which is 2/3 the length of the inner marginal spine; the small marginal spine was absent in the present specimen.
