Distribution map of Clausocalanus dubius by geographical zones
NW Pacif., Okhotsk Sea, off SE Hokkaido, Vancouver Is.
N: 3
(131) M: 1,8; {M: 1,80}
Rem.: Species doubtful.
For Frost & Flelminger (1968, p.82) the description of this species does not agree with the diagnosis of the genus, and it seems preferable to designate dubius as a species incertae sedis.
