Espèce Bradyidius armatus - Planche 1 de figures morphologiquesissued from : G.O. Sars in An Account of the Crustacea of Norway. Vol. IV. Copepoda Calanoida. Published by the Bergen Museum, 1903. [Pl.XIX]. As Undinopsis Bradyi.
Female & Male.
R = rostrum (frontal view); pr = corner of the last thoracic segment; M = Md; m = Mx1; mp1 = Mx2; Mp2 = Mxp.

Nota Female: Eye very conspicuous, bright red (in the living animal), and oblong in form. Exopod of A2 scarcely longer than the endopod. Endopod of 2nd to 4th swimming legs with scatterad small spinules on the posterior face. Ovaries purple-coloured.


Espèce Bradyidius armatus - Planche 2 de figures morphologiquesissued from : G.O. Sars in An Account of the Crustacea of Norway. Vol. IV. Copepoda Calanoida. Published by the Bergen Museum, 1903. [Pl.XX]. As Undinopsis Bradyi.
Female.
mp1 = Mx2


Espèce Bradyidius armatus - Planche 3 de figures morphologiquesissued from : A. Scott in Siboga-Expedition, 1909, XIX a. [Plate VI, Figs.1-11].
Female (from Indonesia-Malaysia): 1, habitus (dorsal); 2, forehead (lateral); 3, last thoracic and genital segments (left side); 4, rostrum; 5, A1; 6, A2; 7, Mx2; 8, Mxp; 9, P1; 10, P2; 11, P4.
Nota: The 'Siboga' specimens differ from the Norwegian form in size, and in length of the spines of the last thoracic segment. A comprison between the 'Siboga' specimens with examples from the Firth of Clyde, with the exception of the size, appear similar.


Espèce Bradyidius armatus - Planche 4 de figures morphologiquesissued from : T. Mori in The pelagic Copepoda from the neighbouring waters of Japan, 1937 (2nd edit., 1964). [Pl.17, Figs.1-5]. With doubt.
Female: 1, 4, habitus (lateral and dorsal, respectively); 2, P4; 3, A2; 5, Mx1.


Espèce Bradyidius armatus - Planche 5 de figures morphologiquesissued from : T. Mori in The pelagic Copepoda from the neighbouring waters of Japan, 1937 (2nd edit., 1964). [Pl.16, Figs.14-16]. With doubt.
Female: 14, P2; 15, P1; 16, P3.

Female (from Langesundsforden, Norway): 1-2, last segment of prosome and urosome; 3-5, last segment of prosome and genital segment (left lateral, right lateral and dorasal, respectively); 6, exopod of A2; 7, Md; 8, P1; 9, P2; 10, rostrum.

Nota : Cephalothorx about 3-4 times longer than urosome. Rostral rami divergent. A1 nearly as long as cephalothorax, reaching or exceeding posterior border of genital segment. Exopodite 1 of A2 without setae, exopodite 2 with 3 setae. Endopodite 1 of Md with 2, endopodite 2 with 9 setae. Posterior corners of last thoracic segment divergent, their points exceeding posterior boder of genital segment. Spermatheca rounded. External spine at exopodite 1 of P1 slightly exceeding the base of the following spine. Posterior surfaces of endopod of P2-P4 with minute spinules.

3 - Points of last thoracic segment straight.
4 - Genital segment 1.2-1.3 times wider than long. Exopodal segment 1 of A2 without seta. Spermatheca rounded.
