Ref.:
Roe, 1975 (p.317, Rem.M, figs.M)
Espèce Scaphocalanus sp. - Planche 1 de figures morphologiquesissued from : H.S.J. Roe in Bull. British Mus. (Nat. Hist.) Zool., London, 1975, 28 (7). [p.312, Fig.9h-r].
Male (from Cape Verde Islands): h, habitus (dorsal); i, A2; j, mandibular palp of Md; k, Mx1; l, Mx2; m, Mxp; n, P1; o, P2; p, P4 (basipodite segments); q, P5; r, 3rd exopodite segment of left P5.
Bar scale 0.1 mm unless indicated.
Nota: Rostrum with 2 thickened filaments.
Head and 1st thoracic segment fused, 4th and 5th partially fused.
Ce^halothorax 1.9 times as long as the 5-segmented abdomen.
The urosome segments and furca are in the proportional lengths as 13:26:21:29:3:8 = 100.
A1 20-segmented (the first eight segments have long sensory setae) reaches back to the hind edge of the 2nd urosomal segment.
Basipodite segments of P2-P4 covered with small surface spines which are particularly dense on legs P3 and P4.
P5 reaches back to the end of the abdomen; on the left side the exopodite is much shorter than the endopodite, the last exopodite segment has some coarse setae and a lamelle, and the endopodite has no marked swelling along its length.

Rem.: According to Roe (1975, p.318) the three specimens cannot be identified with any of the known Scaphocalanus males. The abdomen, with an unswollen 2nd segment, is similar to that described for S. echinatus by Tanaka (1961) but the P5 show differences.
