Female from off Cap Blanc, Mauritania): 1, dorsal view; 2, lateral view; 3, Urosome (lateral); 4, Urosome (ventral); 5, Anal segment and Furca; 6, P4; 7, A1 (proximal segments); 11, Rostrum;

Male: 8, dorsal view; 9, lateral view; 10, A1 (dital segments); 12, Rostrum.

Species Yrocalanus admirabilis - Plate 2 of morphological figuresissued from : V.N. Andronov in Zool. Zh., 1992, 71 (7). [ p.142, Fig.2]. As Ryocalanus admirabilis.
Female: 1, A2; 2, Md; 3, Mx1; 4, Mx2; 5, Mxp.

Male: 6-10, P1 to P5.
Nota: The structure of genicular A1 differs from A1 of other Calanoida genera not only by the position of the bend place, but also that A1 bends out backward but not forward as in all other known calanoid copepods.
