Plate 1 issued from : Brodsky K.A., Vyshkvartseva N.V., Kos M.S. & Markhaseva E.L. in Opred. Faune SSSR, 1983, 135. [p.293, Fig.141]. Male: a, habitus (dorsal view); Ce, head and first segments of left and right A1 (dorsal).
abyssopelagic. Sargasso Sea (Station "S"): 500-2000 m. Only the male has been maintained and not the female (= S. brevicaudatus ). It is likely that certain geographic locality records are contestable. I have no information concerning the sex concerning this species in Deevey & Brooks (1977), but probably female.
