Female (Izu Region): a, forehead (left lateral side); b, last thoracic segment and urosome (left lateral side); c, urosome (dorsal); d, rostrum; e, P2; f, endopod of P3; g, P5.

Male: h, habitus (dorsal); i, last thoracic segment and urosome (left lateral side); j, exopod of left P5; k, exopod of right P5.

Nota Female:
- Cephalothorax about 4.37 times the abdomen length (1.66 : 0.38)
- Rostrum gradually attenuate into slender filaments.
- Abdominal segments and caudal rami in the proportional lengths 43 : 19 : 17 : 2 : 19 = 100.
- Caudal rami 1.6 times as long as wide.
- A1 21-segmented, reaches back to the end of caudal rami.
- A2 exopod shorter than endopod (29 : 32).
- Md exopod 2 times as long as endopod.
- Mx1 with 7 long and 2 short setae on the outer lobe, 6 setae on exopod, 5+4 setae on endopod, 5 setae on 2nd basal.- Mx2 with 3 long vermiform and 5 amalliform sensory filaments on endopod.
- P5 as in female of S. dentata (Giesbrecht, 1892), but the inner marginal spine very strong.

Nota Male:
- Cephalothorax about 2.49 times the abdomen length (1.59 : 0.64).
- A1 reaches back to the middle of the 4th abdominal segment.

- P5 extends about to the distal margin of the 4th abdominal segment; resembles to that of S. dentata (Giesbrecht, 1892), but the distal segment of exopod of the left leg is shorter than the preceding segment; the apex of the segment furnished with a sort of lamella; the inner margin of the segment furnished with short hairs.

Rem.: méso-bathypélagique.
Sampling depth (sub-Antarct.) : 0-500 m.
La confusion avec S. abyssalis est fréquente d'où une distribution géographique incertaine.
Pour Vervoort (1965) les deux espèces pourraient être synonymes.
