Female (from G. of Mexico): 1, urosome (ventral); 3, habitus (lateral); 4, left posterior thoracic margin with P5 and genital segment (lateral); 5, P5; 7, habitus (dorsal); 8, A2; 9, P5; 10, P4; 11, P3; 12, P2; 13, P1; 15, Md (cutting edge).
Nota: Cephalon and thoracic segment 1 separated by weak suture (as in
gyransTerminal portions of thoracic fusion segment 4-5 asymmetrical, in dorsal view left side extending more posteriad; in lateral view right side somewhat truncate and lacking spiniform process, left side extending posteroventrad in lobiform process. A1 about as long as combined lengths of cephalothorax and genital segment; segments 1-2 partially fused, 8-9 completely fused
Genital segment in dorsal view with asymmetrical lateral swellings, swelling of left side larger, right side bearing 1 lateral spine; occasionally 2 lateral spines present; posterior margin of genital orifice with elongated spine (differing from that in
gyrans and
fultoni; spine relatively straight, midventral, and extending posteriad to approximate midlength of following segment.
P5 similar in shape to those of
gyrans, differing in spinal ornamentation; 2nd segment with distal border bearing horizontal row of spinules; terminal segment with horizontal row of styliform spinules at approximate midlength, row of scalelike spinules on distal half of lateral margin, and fine hairs on medial margin.
Male: 2, posterior thoracic segments with P5 and urosome; 6, habiyus (dorsal); 14, P5.
Nota: A1 barely as long as cephalothorax.
Cephalic appendages similar to those in
S. lamellatus (vide Sars 1902, Pl.42).
Rotrum absent.
Genital segment asymmetrical in dorsal view, left side extending farther laterad than right; left side in lateral view with oblique ridge.
2nd abdominal segment with left posteroventral portion produced in short hooked process (similar hooked process also typical of
S. arcticus Sars.
Right P5 with terminal segment spiniform, distal half curved, proximal half straight, inner margin bordered by low lamella; Left P5 with penultimate segment tumid, proximal portion with falcate spiniform process and scooplike process, midportion with elongate lamelliform process bearing proximal spur; short terminal segment with apical rodlike, subapical scooplike process, lateral scooplike process; anteromedial portion of terminal segment with 2 short thick spines.
