Species Euaugaptilus maxillaris - Plate 1 of morphological figuresissued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.238, Fig.20].
Female: a, forehead (dorsal, rostrum underneath); b, forehead (lateral); c, urosome (dorsal); d, idem (lateral left side); e, A2; f, Md (mandibular palp); g, Mx1; h, Mxp; i, P1; j, P5.
Nota: The urosome segments and furca are in the proportional lengths as 59:10:11:20 = 100. Prosome and urosome are in the proportional lengths as 78:22. A1 extends beyond the furca by 5 segments.

Species Euaugaptilus maxillaris - Plate 2 of morphological figuresissued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.198, Fig.1,d].
Female: d, mandibular teeth.

Female: 1, habitus (dorsal); 2, idem (lateral left side); 3, rostrum; 4, A2; 5, Md; 6, Mx1; 7, Mx2; 8, Mxp; 9, P1; 10, P2; 11, P3; 12, P5; 13, anal segment and left caudal ramus (dorsal).

Species Euaugaptilus maxillaris - Plate 4 of morphological figuresissued from : T. Park inBiology of the Antarctic Seas, XXII. Antarct. Res. Ser., Washington, 58. [p.4, Fig.1].
Female: a, habitus (lateral); b-c, forehead (ventral and lateral, respectively); d-e, urosome (lateral and dorsal, respectively); f, A2; g, Md; h, Mx1.
Nota: 1st endopodal segment of Md with 2 setae.

Species Euaugaptilus maxillaris - Plate 5 of morphological figuresissued from : T. Park inBiology of the Antarctic Seas, XXII. Antarct. Res. Ser., Washington, 58. [p.5, Fig.2].
Female: a, Mx2; b, Mxp; c-g, P1 to P5 (anterior views).
Nota: None of maxillary setae armed with hooked spinules (\"buttons\")

Species Euaugaptilus maxillaris - Plate 6 of morphological figuresissued from : H.S.J. Roe in Bull. British Mus. (Natural History) Zool., London, 1975, 28 (7). [p.354, Fig.27].
Female: a, habitus (dorsal); b, rostrum (ventral); c, mandibular palp; d, masticatory edge of Md; e, Mx1; f, Mx1 (from small specimen); g, Mx2;
Nota: The variation in structure of Mx1 accords with the intraspecific variations noted in Euaugaptilus by Matthews (1972) and by Tanaka & Omori (1974). Similar differences are also present in several of the species described here.

Male: h, habitus (dorsal); i, P5.

Bar scale 0.1 mm unless indicated.
