Cyclaspis elegans Calman 1907

Diagnosis. Female. Carapace granulated, with many stout ridges, quadrilateral depression on sides bounded by strong ridges, rising into prominent tubercles at corners; 0.7 as high as long; eyelobe with lenses; antennal notch oblique; anteroventral corner smooth. Pereonite 1 only visible from side. Pereonite 2 produced dorsally as large tooth directed posteriorly. Pleon with lateral articular pegs. Uropod peduncles shorter than pleonite 6; endopod subequal to exopod; endopod with with single seta medially; exopod with plumose setae medially. Male. Carapce with similar pattern of ridges as in female, but less strongly pronounced, tubercles at corners of depression smaller; 0.5 as high as long. Pereonite 1 entirely concealed. Appendages with more setae than in female. Uropod peduncles longer than pleonite 6; endopod slightly shorter than exopod.

Remarks. This is the most strongly ornamented of the Cyclaspis currently described from New Zealand. The most similar species is C. similis , which can be differentiated by the carapace ornamentation being much less strongly marked, with a similar depression on the sides but without tubercles at the corners of the depression.
