New Zealand, Antarct. (exceptional)
N: 5
(35) F: 1,23-1,17; M: 1,05-0,96; (435) F: 1,23-1,04; M: 1,1-0,92; {F: 1,04-1,23; M: 0,92-1,10}
Rem.: For Bradford (1978, p.138) this species is most closely related to C. tenuis Giesbrecht, 1891 and C. lubbocki Giesbrecht, 1891.
For Boxshall & Halsey (2004, p.491) the subgenus (Dahl, 1912) is considered as full generic status pending phylogenetic revision of the whole family at the generic level.
