| | | | | | | Ref.: | | | Vyshkvartzeva & Prusova, 1997 (p.33, Descr.F, figs.F) |  issued from : N.V. Vyshkvartzeva & I.J. Prusova in Zoosysst. Ross., 1997, 6 (1/2). [p.34], Fig.1-7; Female (03° 49'N, 48°55 E): 1, habitus (lateral); 2, forehead (lateral); 3, idem (ventral); 4, urosome (dorsal); 5, last thoracic segment and urosome (lateral, right side); 6, 1st and 2nd urosomal segments (lateral, right side); 7, genital somite (ventral). 1-5: holotype; 6-7: paratype. Nota: Head and 1st thoracic segment fused, 4th and 5th incompletely separate. Posterior corner of the last thoracic segment slightly produced into a broadly rounded lobe, covering anterior third of the genital somite in lateral view. Rostrum reduced, as a short plate with 2 short thin filaments. Urosome 3.6-4.0 times shorter than prosome. A1 reaching posterior end of prosome; segments8-9 fused, 9-10 partly fused. Endopod of A2 slightly longer than the exopod.

 issued from : N.V. Vyshkvartzeva & I.J. Prusova in Zoosysst. Ross., 1997, 6 (1/2). [p.35, Fig.8-13]; Female: 8, P1; 9, P2; 10, P3; 11, P4; 12, Mx1; 13, P5. 8,9,11-13: holotype; 10: paratype. Nota: Mx1: 1st inner lobe with 1 anterior, 9 terminal and 2 posterior setae; 2nd and 3rd inner lobes with 2 and 3 setae respectively; basis with 5 setae, endopod with 2+6, exopod with 6, and outer coxal lobe with 9 setae. Mx2: 5th inner lobe with 2 long and 1 short setae and 1 worm-like sensory filament; endopod distally with 3 worm-like and 5 brush-like sensory filaments (two of 5 brush-like about half as long as 3 others and with slightly thicker brushes. Mxp: protopodite with 2 worm-like filaments and 1 seta in proximal part, 1 short brush-like sensory filament in the middle of segment and 3 setae distally. P5: 2-segmented, distal half of segment with 3 setae, terminal seta slightly longer than segment, reaching about 2/3 length of inner seta; inner seta twice longer than segment and 1.8 times longer than terminal seta, with 18-23 strong setules along inner edge; minute outer seta opposite to inner seta.

| | | | | | | Loc: | | | NW Indian (off Somalia) | | | | N: | 1 | | | | Lg.: | | | (157) F: 2-1,77; {F: 1,77-2,00} | | | | Rem.: | mesopelagic (200-600 m).
For Vyshkvartzeva (1997, p.33) the species is very similar to S. brevirostris Park, 1970, but distinguished by the setation of Mx1 and P5. | | | Dernière mise à jour : 31/01/2015 | |
