Spinulation variable, in some specimen the outer marginal spine is absent (see figs. i, J, k). Nota Male: - Cephalothorax and abdomen in the proportional lengths 72 : 28. - Posterolateral corners of the last thoracic segment rounded. - Abdominal segments and caudal rami in the proportional lengths 15 : 30 : 21 : 21 : 4.9 = 100. - Caudal rami divergent, about as long as wide. - A1 extends to the distal margin of the 3rd abdominal segment. - P5 extends to the distal margin of the 4th abdominal segment.

Sampling depth (sub-Antarct.) : 0-2500 m. Sargasso Sea: 500-1000 m ( Deevey & Brooks, 1977, Station "S"). 150-180 m (Pipe & Coombs, 1980 at 60°N, 07°W).
Distributional range (m) from Roe (1972) Day: 205-625, Night: 50-700; from Grice & Hulsemann (1965): 100-1000 (in Kuriyama & Nishida, 2006).
According to Østvedt (1955) this species has not previously been repôrted from the Norwegian Sea.
See remark in Scolecithrix dubia.
For Mazzocchi & al. (1995) most of the females collected lacked a P5 (careful examination of the specimens gave no sign of the presence of this leg). Noted also by Campaner (1984) in the material from epipelagic waters off Southern Brazil.
After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 5 corresponding to small sac-spawning detritivorous. | | | Last update : 25/10/2022 | |
