Sampling depth (sub-Antarct.) : 0-500 m.
Distributional range (m) from Roe (1972) Day: 250-950, Night: 220-720 (in Kuriyama & Nishida, 2006).
Female: habitus (dorsal), general appearance as in the male.
Fof Park (1980, p.36) this species is pratically identical in morphological details to S. abyssalis (Giesbrecht, 1888) originally described from deep waters of the tropical Pacific and has been known to occur in almost all geographical areas where the former has been recorded.
According to Giesbrecht (1892), the two species are distinguishable by small differences in the shape of P5 like in the figures in Park (1980). The latter author finds S. profunda, all north to 49°S.
For Vervoort (1965, p.80) the two species could be synonyms.
The confusion with S. abyssalis is frequent, hence an uncertain geographical distribution.
