Euaugaptilus austrinus  Park, 1993   (F,M)
Ref.:
Park, 1993 (p.37, figs.F,M); Bradford-Grieve & al., 1999 (p.882, 939, figs.F); Park & Ferrari, 2009 (p.143, Table 3, Appendix 1, biogeography from Southern Ocean)
Species Euaugaptilus austrinus - Plate 1 of morphological figuresissued from : T. Park in Biology of the Antarctic Seas, XXII. Antarct. Res. Ser., Washington, 58. [p.38, Fig.26].
Female: a, habitus (lateral); b-d, forehead (lateral, ventral and dorsal, respectively); e-f, urosome (dorsal and lateral, respectively); g, genital segment (lateral); h, A2; i, Md; j, Md (biting edge).
Nota: Mandibular blade with 3 pairs of relatively short teeth, last pair with a very small tooth in between, basal spine absent, toothed edge only slightly oblique to long axis of blade; mandibular palp about 51 % length of blade including coxa; endopod about as long as exopod with 6 terminal setae.


Species Euaugaptilus austrinus - Plate 2 of morphological figuresissued from : T. Park in Biology of the Antarctic Seas, XXII. Antarct. Res. Ser., Washington, 58. [p.39, Fig.27].
Female: a, Mx1; b, Mx2; c, Mxp; d-h, P1 to P5 (anterior views).


Species Euaugaptilus austrinus - Plate 3 of morphological figuresissued from : T. Park in Biology of the Antarctic Seas, XXII. Antarct. Res. Ser., Washington, 58. [p.40, Fig.28].
Male: a, forehead (lateral); b, urosome (dorsal); c, Md (biting edge.


Species Euaugaptilus austrinus - Plate 4 of morphological figuresissued from : J.M. Bradford-Grieve, E.L. Markhaseva & C.E.F. Rocha & B. Abiahy in South Atlantic Zooplankton, Edit. D. Boltovskoy. 1999, Vol.2. Copepoda. [p.1036, Fig. 7.244].
Female: Mx1; A2 (schematic diagrams). Li = inner lobe; Le = outer lobe; Exp = exopodite.
Exopod of A2 with 4 setae. Exopod of Mx1 with 4 setae; outer lobe 1 with 9 setae. Distal end of Md gnathobase hardly cut obliquely and with short teeth.

Distribution map of Euaugaptilus austrinus by geographical zones
Loc:
Antarct. (SW Atlant., SW & SE Pacif.), Indonesia (Celebes Sea)
N: 3
Lg.:
(48) F: 9,2-8,35; M: 8,59; {F: 8,35-9,2; M: 8,59}
Rem.: Meso-bathypelagic.
Sampling depth (Antarct.) : 0-1000-3000 m.
For Park (1993, p.41) the species is very similar to E. magnus (Wolfenden, 1904) but can be distinguished from it by the large body, relative size of the Md palp, shape of the Md palp, and setation of the A2, Md, Mx1 and Mx2.
First occurrence in Indonesia waters by Matsuura & al. (2010).
