Sampling depth (Antarct., sub-Antarct.) : 0-1000 m.
Certain locality records in the subtropical Atlantic and in the Mediterranean Sea result from a confusion with O. pseudofrigida. For Vervvort (1951, p.149) a closely related form, differing from the typical O. frigida in the spinulation of the swimming legs (the number of outer edge spines on the P3 and P4) has been described as O. frigida var. pseudofrigida Rosendorn (1917 a, p.19) from the Atlantic and Indian Oceans.
Nishida (1985, p.48) points to this species and closely allied O. pseudofrigida possess 2 setae on the free segment of P5, but are closely related to O. plumifera and O. setigera and quite different from those species placed in Dioithona by Kiefer (1935). This suggests that the present subgenus Dioithona, as presently defined, does not represent a monophyletic group. | | | Last update : 14/11/2012 | |
