Espèce Euaugaptilus angustus - Planche 1 de figures morphologiquesissued from : O. Tanaka in Publs Seto Mar. Biol. Lab., 1964, XII (1). [p.57, Fig.201].
Female: a, habitus (dorsal); b, forehead (left lateral side); c, rostrum (frontal view); d, last thoracic segment and urosome (left lateral side); e, urosome (ventral); f, A2; g, Md (mandibular palp and biting blade, separately); h, Mx2; i, P1; j, P5.
Nota: The urosome segments and furca are in the proportional lengths as 53:9:11:27 = 100.


Espèce Euaugaptilus angustus - Planche 2 de figures morphologiquesissued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.202, Fig.4].
Female: a, Mx1.

Male: b, forehead (dorsal); c, last thoracic segment and urosome (dorsal); d, distal part of A1.
Nota: The urosome segments and furca are in the proportional lengths as 25:13:11:11:11:29. Left A1 modified.


Espèce Euaugaptilus angustus - Planche 3 de figures morphologiquesissued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.200, Fig.3,a].
Female (from Izu region): a, mandibular teeth.


Espèce Euaugaptilus angustus - Planche 4 de figures morphologiquesIssued from : G.O. Sars in Résult. Camp. Scient. Prince Albert I, 69, pls.1-127 (1924). [Pl.XCI, figs.1-14].
Female: 1, habitus (dorsal); 2, idem (lateral left side); 3, rostral prominence (ventral view); 4, A2; 5, Md; 6, Mx1; 7, Mx2; 8, Mxp; 9, P1; 10, P3; 11, P5.

Male: 12, forehead (lateral); 13, P5; 14, posterior part of urosome (dorsal).


Espèce Euaugaptilus angustus - Planche 5 de figures morphologiquesissued from : R.B.S. Sewell in The John Murray Expedition, 1933-34, Scientific Reports, VIII (1), 1947. [p.224, Fig.60, E].
Female (from N Arabian Sea): E, Mx1.
Nota: The specimenn differs from that figured by Sars in that the 2nd basal segment of Mx1 on one side bears only 2 setae, whereas Sars (1925, fig.6) shows it as having 3. A gland opens on the anterior margin of inner lobe not far from the origin of the most anterior spine.


Espèce Euaugaptilus angustus - Planche 6 de figures morphologiquesissued from : T. Park in Biology of the Antarctic Seas, XXII. Antarct. Res. Ser., Washington, 58. [p.28, Fig.19].
Female: a, forehead (lateral); b, genital segment (lateral); c, A2; d, Md; e, Md (biting edge); f, Mx1; g, Mx2; h, Mxp.
Nota: Forehead (laterally) broadly round, with rostrum in the form of a round tubercle, without filaments


Espèce Euaugaptilus angustus - Planche 7 de figures morphologiquesissued from : T. Park in Biology of the Antarctic Seas, XXII. Antarct. Res. Ser., Washington, 58. [p.29, Fig.20].
Female: a-e, P1 to P5 (anterior views).


Espèce Euaugaptilus angustus - Planche 8 de figures morphologiquesissued from : H. Matsuura, S. Nishida & J. Nishikawa in Deep-Sea Res. II, 2010, 57. [p.2106, Fig.10, g-h].
From Sulu Sea: g, SEM image of button setae on Mx2 and Mxp; h, SEM image of mandible blade.
Nota: Mandible blade like a curved needle and with 4 spiniform teeth (Type-I).


Espèce Euaugaptilus angustus - Planche 9 de figures morphologiquesissued from : J.B.L. Matthews in Bull. Br. Mus. (Nat. Hist.) Zool., 1972, 24 (1). [p.25, Table 2].
Differences in setation of Mx1, according to previous descriptions.
Nota: Sewell mentioned 2 setae present on one side but drew 3, presumably from the other side.
