 issued from : B. Morris in J. Fish. Res. Bd Canada, 1970, 27 (12). [p.2313, Fig.8]. Female (from subtropical central North Pacific): A, forehead (lateral); B, rostrum (anterior); C-D, posterior prosome and urosome (lateral and dorsal, respectively); E, P1 (anterior); F, P2 (anterior); G, P3 (anterior); H, P4 (anterior); I, P5; J, distal segments of left P5. Nota: Body of rich brown color. Prosome to urosome ratio 45: 10. General shape as in S. helenae but cephalic crest more rounded. Rostral plate width (at base) to length (from base to tips of points) in ratio of 10 : 11. Rostral poins occupying 0.5 depth of depression. Lateral margins of rostral plates slightly inflated. A1 24-segmented. 5th thoracic segment (in lateral view) produced into bluntly triangular corners and emarginate below. Corners (in dorsal view) triangularly produced with small, knoblike tips. Urosome 4-segmented. Proportional lengths of urosomal segments and caudal rami 68 : 27 : 23 : 10 : 35. Genital segment symmetrical with moderate ventral swelling. Urosome segments without teeth along distal margins. P2 and P3-P4 with distinctive spinulation on anterior surface of exopodite and endopodite. Exopodite of P4 without anterior spinulation. P5 with 1 free segment on each side. Apical spine short and triangular, and with a small spinule at its base. Outer spine long and haired along distal half. Small spinule near base of outer spine. Rem.: With (1915) and Sars (1925, as S. persecans describe and illustrate this specis, but they differ in certain details. The posterior corners of prosome are more produced in With’s females and the long outer spine of the P5 extends almost to the distal margin of the 2nd urosomal segment, whereas in Sars’s specimens this spine does not reach the anterior margin of the urosomal segment 2.

Mxp as in S. helenae but apparently with only 2 setae plus 1 sensory appendage on proximal of basipod 1.

Cette espèce semble avoir été confondue avec S. persecans et S. helenae par divers auteurs (voir synonymies in Vervoort, 1965). Park doute de la validité de certains synonymes. la distribution géographique précise de ces diverses espèces demeure incertaine.
