With (1915, p.60) underlines the occurrence of a female P5 in certain individuals (possibly in confusion with P. elongatus.
The presence of this Arctic species in the Mediterranean Sea, in the Red Sea and in the temperate Atlantic Ocean requires confirmation.
Characteristics according to Frost (1989): See limits of lenght measurements in the figure of the genus Pseudocalanus.
Female: Frontal part in lateral view ogival; posterovental margins of Th1 and Th2 with long spiniform processes; ratio sizes of P4 B1:B2 > 1.5; ratio size Prosome: Urosome = 2.39 (2.22-2.52).
Male: ratio of lenghts of P4 B1:B2 > 1.5; ratio of lenghts of segments of P4 (8-12):(20-21) > 2.0; ratio of lenghts Cephalosome: U2 = 5.71 (5.19-6.15). | | | Last update : 03/06/2010 | |
