The mean female size is 1.653 mm (n = 17; SD = 0.1895), and the mean male size is 1.467 mm (on 3 specimens only). The size ratio (male : female) would be approximately 0.96. | | | | Rem.: | Vervoort (1963 b) émet des doutes sur l’identification de cette espèce par Tanaka (1953, 1957) et Tanaka & Omori (1970).
Markhaseva (1996) n’ admet pas la validité des mâles décrits par Wilson (1950) et Tanaka (1957 a).
Sampling depth (Antarct., sub-Antarct.) : 0-100 m.
