Remarks

After Huys & Conroy-Dalton (2000, p.24) the male of this species differs from all known males in: 1- the ventral ornamentation pattern of the urosome, displaying spinules on all postgenital somites; 2- the extreme elongation of the P5 and P6. This species has the same swimming leg setal formula as C. setosa but, in addition to the characters listed , differs from the latter in body size and the presence of the proximal endite on the maxillary (Mx2) syncoxa.

Identification characters after G.A. Boxshall & S.H. Halsey (2004, p.278):
1- Exopod of P1 with 4 distal setal elements; female A1 7-segmented.
2- Exopod of P5 in both sexes armed with 5 setae; 3rd exopodal segment of P2 with total of 6 spines/setae.
3- 3rd exopodal segment of P3 and P4 each with total of 7 spines/setae.
4- Male P5 elongate, with apex of exopodal segment extending to posterior margin of 1st free abdominal somite; Mx2 with proximal seta on syncoxa representing endite.
