Distribution map of Pseudochirella notacantha by geographical zones
Loc:
Antarct. (Atlant. SW, Indien, Pacif. SW, S), Atlant. (tempéré & boréal), G. de Guinée, off Mauritanie, off Madère, ? G. de Gascogne, Açores, Mer des Sargasses, Station "S" (32°10'N, 64°30'W), off Delaware, off E Cape Cod, Détr. de Davis S, Islande S, off Irlande W, ? Mer Arabe, Is. Laquedives S, Indien SW, Japon (in/em> Morioka, 1972 a, p.314), Nouvelle-Zélande, Pacif. S, Is. Juan Fernandez, Pérou S, off Is. Juan Fernandez, Chili N & S (sub-Antarct.)
N: 22
Lg.:
(1) M: 4,9; (7) juv.F: 4,42; M: 5,28; (14) M: 5,1-4,9; (37) F: 6,8-5,45; M: 5,8-4,9; (264) F: 6,8-5,5; M: 5,8-5,1; {F: 5,10-6,80; M: 4,90-5,80}
Rem.: epi- to bathypelagic. Sargasso Sea: 500-2000 m (Deevey & Brooks, 1977, station "S");
Sampling depth (Antarct.) : 0-750-1000+ m.
The male described by With (1915) does not seem to be a synonym of any other species.
Vervoort (1952 g) and Markhaseva (1996) do not agree on the synonymy between Chirudina parvispina in With (1915) and P. notacantha.
For Grice & Hulsemann (1967, p.24) the female specimen resembles P. obesa.
