Euaugaptilus marginatus Tanaka, 1964 (F) | |
| | | | | | | Syn.: | Euaugaptilus longiantennalis Park, 1970 (p.478, 533, figs.F); Cummings, 1984 (p.177) | | | | Ref.: | | | Tanaka, 1964 b (p.64, Descr.F, figs.F); Matthews, 1972 (p.36); Tanaka & Omori, 1974 (p.199, 200: fig.F) |  issued from : O. Tanaka in Publs Seto Mar. Biol. Lab., 1964, XII (1). [p.65, Fig.205]. Female (from Sagami Bay): a, habitus (dorsal); b, forehead (left lateral side); c, last thoracic segment and urosome (left lateral side); d, urosome (ventral); e, A2; f, Md; g, Mx1; h, Mx2; i, Mxp; j, P1; j, P5. Nota: Proportional lengths of cephalothorax to abdomen 72: 28. Abdomen 3-segmented. The abdominal segments and furca are in the proportional lengths as 55:12:13:20 = 100. A1 25-segmented, exceeds the end of the furca by distal 8 segments. Md: exopod as long as endopod; exopod with 5 marginal setae; cutting edge with 4 teeth, the anterior very strong. Mx1: outer lobe with 3 long setae; exopod with 7 setae of which the terminal 2 are very long; 2nd basal segment with 3 setae; 3rd inner lobe with 1 seta; 1st inner lobe with 7 spines; endopod and 2nd inner lobe absent. Mx2 slender with on the lobes 1 to 6 and endopod: 3setae and a small spine on the 1st lobe, 2 setae on the 2nd, 2 setae on the 3rd; 3 setae on the 4th; 2 setae on the 5th; 1 seta on the 6th; 7 setae on the endopod. Mxp: 1st basal segment as long as the 2nd; the 2nd basal segment has a row of hair-like spines on the anterior margin. P5 3-segmented exopod and endopod; the inner marginal spine of the 2nd exopodal segment short, extends a little beyond the base of the inner marginal seta of the 3rd exopodal segment.

Female (from Caribbean Sea): 318, habitus (lateral left side)319, idem (dorsal); 320, head (ventral); 321, Md; 322, Mx1; 323, Mxp; 324, P5 (posterior); Nota: Prosome about 4 times length of urosome. Rostrum consisting of 2 slender filaments. Genital segment as long as the rest of urosome. Caudal ramus as long as anal segment. Mandibular palp biramous, exopod carrying 4 setae and shorter than endopod. Mx1 with 1 seta on 3rd inner lobe; 3 setae on basis; 7 setae on exopod; 6 setae on outer lobe; 2nd inner lobe and endopod missing. Both rami of P5 3-segmented; 1st and 2nd exopodal segments without external spines.

Distribution map of Euaugaptilus marginatus by geographical zones
|
| | | | | | | Loc: | | | Caribbean Sea, G. of Mexico, Indonesia (Celebes Sea), China Seas (East China Sea), Taiwan, Japan (Izu), W Pacif. (equatorial)
Type locality: Sagami Bay (middle Japan). | | | | N: | 5 | | | | Lg.: | | | (69) F: 2,26; (88) F: 1,66; {F: 1,66-2,26} | | | | Rem.: | epi-mesopelagic. Obtained at depths between 100 and 450 m (Matthews, 1972).
The species closely resembles E. hecticus (Gisebrecht, 1889).
For Itoh (1970 a, fig.2, from co-ordonates) the Itoh's index value from mandibular gnathobase = 2450.
