 issued from : J.M. Bradford in Mem. N. Z. Oceonogr. Inst., 1972, 54. [p.35, Fig.5 (19-24)]. As Clausocalanus arcuicornis. Female (from Kaikoura, New Zealand): 19, P5; 20 (? parasited female); 21, P5; 22, habitus (dorsal). Male: 23, habitus (dorsal); 24, P5.
Scale bars: 1 mm (22, 23); 0.1 mm (19, 20, 21, 24).
Nota: For J.M. Bradford this form is C. brevipes (pers. comm.). For the author the opaque swollen appearance of the cephalothorax in some specimens suggests that this species may frequently be parasited. One such large (1.8 mm) opaque female did not have a fully developed genital segment, and the P5 had retained the juvenile proportions. Sewell (1951) found that C. arcuicornis in the Arabian Sea parasited by Blastodinium sp. were reduced in size, had modified P5, and an incompletely developed abdomen.
