Euaugaptilus tenuispinus  Sars, 1920   (F)
Ref.:
Sars, 1920 c (p.16, Descr.F); 1925 (p.290, figs.F); Sewell, 1932 (p.322); 1947 (p.197, 199, 200, 219, Redescr.F, figs.F); Vervoort, 1965 (p.140, Rem.); Owre & Foyo, 1967 (p.88, figs.F); Matthews, 1972 (p.25, 43); Tanaka & Omori, 1974 (p.258, figs.F, Rem.); Bradford-Grieve & al., 1999 (p.882, 940, figs.F); Vives & Shmeleva, 2007 (p.212, figs.F, Rem.)
Espèce Euaugaptilus tenuispinus - Planche 1 de figures morphologiquesissued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.259, Fig.30].
Female: a, forehead (dorsal); b, idem (lateral); c, last thoracic segment and urosome (dorsal); d, idem (lateral left side); e, Md; f, Mx1; g, Mxp; h, P1; i, P2; j, P5.
Nota: The urosome segments and furca are in the proportional lengths as 51:14:15:20 = 100. Prosome and urosome are in the proportional lengths as 80:20. A1 extends beyond the end of the furca by 4 segments.
The specimen has a structure more similar to Sars (1925) than to Sewell (1947).


Espèce Euaugaptilus tenuispinus - Planche 2 de figures morphologiquesissued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.199, Fig.2,h].
Female: h, mandibular teeth.


Espèce Euaugaptilus tenuispinus - Planche 3 de figures morphologiquesIssued from : G.O. Sars in Résult. Camp. Scient. Prince Albert I, 69, pls.1-127 (1924). [Pl.XCVII, figs.1-14].
Female: 1, habitus (dorsal); 2, idem (lateral left side); 3, forehead (lateral); 4, rostrum; 5, A2; 6, Md; 7, Mx1; 8, Mx2; 9, Mxp; 10, P1; 11, P2; 12, P3; 13, P5; 14, anal segment and caudal rami (dorsal).


Espèce Euaugaptilus tenuispinus - Planche 4 de figures morphologiquesissued from : R.B.S. Sewell in The John Murray Expedition, 1933-34, Scientific Reports, VIII (1), 1947. [p.221, Fig.59]. As Euaugaptilus tenuispinus var.
Female (fromN Arabian Sea): A, A2; B, Md; C, Mx1; D, one of the biting spines of inner lobe 1 (enlarged); E, Mx2; F, P1.
Nota: The proportional lengths of the various segments of the body (cephalon to caudal rami) as 358:154:97:88:90:97:28:41:47 = 1000. A small cervical groove crosses the dorsal aspect of the cephalon. A row of fine hairs runs transversely just in front of the genital aperture situated about the middle of the segment. A1 25-segmented (1segments 1 and 2 patlly fused), over-reaches the caudal rami by about the last 3 segments. In A2 the endopod bears 6 setae on the outer lobe and 3 large and 4 small setae on the inner lobe; exopod 8-segmented. In Md the biting blade is strong, but the edge is considerably more oblique than figured by Sars, the arrangement of the teeth is , however, the same; endopod 2-segmented; exopod 5-segmented. In Mx1 the lobes bear the following setae: inner lobe 1 (11 setae, of which 7 are fringed with closely set \"buttons\"), inner lobe 2 (1 large seta), inner lobe 3 (1 small seta); segment basal 2 (2 setae instead 3 in Sars); exopod (4 setae on the outer margin and 2 large and 1 small distally); outer lobe (6 large and 3 small setae). In Mx2 bears the following setae: lobe 1 with 3 setae and a very short pointed process, lobe 2 (2), lobe 3 (2), lobe 4 (3), lobe 5 (2), lobe 6 (3); endopod with 7 setae. Most of the setae are fringed with \"buttons\".

Female: Mx1.

Nota: inner lobe 4 with 3 setae; Endopod absent.

Differences in setation of Mx1, according to previous descriptions.
