Remarques

epipelagic.
After Nishida & al. (1977) this species is the same as Shuvalov's (1972) southern, smaller form of O. atlantica. See Remarks in Yoo & Lim (1993, p.93) in Oithona atlantica in the Korean Waters.
After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 6 corresponding to small ambush feeding omnivorous.
