Loc:
SE Indian, Bay of Bengal, China Seas (East China Sea South China Sea), off E Taiwan, S Korea, Japan, off Hachijo Is., Bikini Is., W Baja California, La Paz (Mexico), Pacif. (W equatorial), E Medit. (W Egyptian coast)
N: 14

(91) F: ± 3,46; (151) F: 3,46; (866) F: 3,9; {F: 3,46-3,90}
Rem.: epi-mesopelagic.
According to Mori (1932a, p.176) this species ressembles C. mediterranea, but the caudal rami are 2 times longer than the posterior division of bedy, the middle spine on the 1st segment of endopodite of A2 is the longest of 3 spines located on the segment.
