Ref.:
Brodsky, 1950 (1967) (p.383, figs.F,M, Rem.); Vidal, 1971a (p.178, 186, figs.F,M); Matthews, 1972 (p.33); Tanaka & Omori, 1974 (p.224, figs.F, Rem.); Roe, 1975 (p.360, figs.F,M, Rem.); Vives & Shmeleva, 2007 (p.221, figs.F,M, Rem.)
Espèce Euaugaptilus hyperboreus - Planche 1 de figures morphologiquesissued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.222, Fig.13].
Female: a, forehead (latezral); b, rostrum (frontal view); c, last thoracic segment and urosome (lateral left side); d, furca; e, A2; f, Md; g, Mx1; h, Mx2; i, Mxp; j, P1; k, endopod of P2; l, P5.
Nota: The urosome segments and furca are in the proportional lengths as 47:11:14:28 = 100. Prosome and urosome are in the proportional lengths as 74:26.

Male: m, last thoracic segment and urosome (dorsal); n, left P5; o, right P5. Nota: The urosome segments and furca are in the proportional lengths as 22,14,12,9,14,29 = 100. Prosome and urosome are in the proportional lengths as 74:26. Left A1 extends beyond the end of the furca by distal 2 segments.


Espèce Euaugaptilus hyperboreus - Planche 2 de figures morphologiquesissued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.198, Fig.1,c].
Female: c, mandibular teeth.


Espèce Euaugaptilus hyperboreus - Planche 3 de figures morphologiquesIssued from : K.A. Brodskii in Calanoida of the Far Eastern Seas and Polar Basin of the USSR. Opred. Fauna SSSR, 1950, 35 (Israel Program for Scientific Translations, Jerusalem, 1967) [p.384, Fig.272].
Female (from central part Arctic): habitus (dorsal and left lateral side); R, rostrum; A2; M, Md (masticatory blade); Mx, Mx1; S1, P1; S5, P5.

Male: S5, P5.


Espèce Euaugaptilus hyperboreus - Planche 4 de figures morphologiquesissued from : H.S.J. Roe in Bull. British Mus. (Nat. Hist.) Zool., London, 1975, 28 (7). [p.359, Table I].
Male (Canarias Is.): a, A2; b, mandibular palp of Md; c, masticatory edge of Md; e, Mx2; f, Mxp; g, P5.
Bar scale 0.1 mm unless indicated.
Nota: This species and E. elongatus are closely related; these two species show consistent differences, especially in the number of endopodite setae on the Mx1 and Mx2.


Espèce Euaugaptilus hyperboreus - Planche 5 de figures morphologiquesissued from : H.S.J. Roe in Bull. British Mus. (Nat. Hist.) Zool., London, 1975, 28 (7). [p.361]. Number of endopodite setae on the Mx1 and Mx2 of E. hyperboreus and E. elongatus.
Nota: In the course of the present work the author borrowed a male and a female specimen of E. elongatus from the Oceanographic Museum, Monaco, both of which were taken at 'Pricesse Alice' . These specimens and the present ' Discovery' material confirm the differences in the setation of the Mx1 and Mx2 observed by Tanaka & Omori (see in Table I). Slight variation occurs in the setation of the Mx1 endopodite of E. hyperboreus, but none of the present specimens, nor those examined by Tanaka & Omori, have 3 setae on this lobe. Some differences are also present in the setation of the 2nd basipodite of the Mx1, where the 'Dicovery' male has 3 setae on the left side but 4 on the right. Similar variations occurs on the endopod of the Mx2 of the male E. elongatus from Monaco (Table I).
The specimens of E. hyperboreus have a spinous ridge at the base of the external exopodite spines of the P1 as described by Tanaka & Omori.
