Planche 1 issued from : A. Fosshagen in Sarsia, 1978, 63. [p.181, Fig.2].
Female (from Norwegian fjords): A, caudal rami (dorsal); B, urosome (dorsal); C, A1; D, Mx1; E, left P5.
Nota: A simgle small rostral filament. A1 23-segmented. P5 as a 1-segmented rudiment on the left side. Caudal rami with 3 transverse rows of dorsal spines, one in the middle, and one terminally; the terminal row is the more extensive and consists of coarser spines; in the middle of the inner margin of the right ramus there is a small ventrally directed seta; proximally on the inner margin of the left ramus there arises a very long seta directed to the right at a right angle to the urosome, this seta is without setules, it narrows distally into a very fine flexible tip; each ramus bears 4 terminal setae, the outermost one relatively weak.

Male: F, urosome (dorsal); G, left A1; H, right A1 (distal segments); I, P5; J, left P5 (distal part).
Nota: No rostral flament could be discerned. last prosomal segment slightly asymmetrical due to an extension of the right distal corner. 1st urosomal segment more prominently on the left side; on each side there is 1 transverse row of long spinules. The long proximal seta on the left caudal ramus in the female is replaced in the male by a small seta. Right A1 22-segmented and the left one 23-segmented; segments 9-12 separate on the right A1 but partly fused on the left, segments 19 and 20 fused on the right A1 but separate on the left A1. Right P5 is a rounded stump, carrying a terminal row of small spines, and near the inner margin a slender spine; the penultimate segment of left P5 bears a pointed distal process; the last segment ends in a strong spine and a blunt, flattened subterminal spine, on each side of which there is a small spine.

Copepodids: K, P5 (stage V Male); L, P5 (stage IV Male); M, P5 (stage V Female).
