Euaugaptilus pachychaeta Matthews, 1972 (F) | |
| | | | | | | Ref.: | | | Matthews, 1972 (p.5, 38, Descr.F, figs.F); Bradford-Grieve & al., 1999 (p.882, 940, figs.F) |  issued from : J.B.L. Matthews in Bull. Br. Mus. (Nat. Hist.) Zool., 1972, 24 (1). [p.6, Fig.1]. Female (from 5°49'N, 3°24'E): A-B, habitus (lateral and dorsal, respectively); C, rostrum (antero-ventral view); D, Md (mandibular gnathobase); E, modified setae on protopodite of Mxp; F, distal outer border of exopodite of P1. A-B to scale I; C-E to scale II; F to scale III. Nota: Prosome length 4.1 times the length of the urosome. head and 1st thoracic segment separated, 4th and 5th thoracic segments fused. Rostrum with 2 filaments of moderate length. The hump in the midveventral line just anterior to the A2 is moderately well developed. Genital segment slightly swollen laterally but more distinctly so ventrally with a small papilla in the region of the genital opening. 2nd urosomal segment short, being only 1/5 the length of the anal segment. Caudal ramus approximately twice as long as it is broad and bears 6 setae. (all bear setules which appear plumose towards the tips of the setae). A1 25-segmebted, the last six reaching past the end of the urosome. None of the setae is markedly plumose.

 issued from : J.B.L. Matthews in Bull. Br. Mus. (Nat. Hist.) Zool., 1972, 24 (1). [p.7, Fig.2]. Female: A, A2; B, Md; C, Mx1; D, Mx2; E, Mxp; F, P1; G, P2; H, P3; I, P4; J, P5. Nota: A2: Exo and endopod subequal; the last two segments of the exo fused; all the setae on the exopod, but not those on the endopod, possess long and often quite thick setules, making these setae very olumose in appearance. Md: gnathobase long, thin, with 6 curved yeeyj set very obliquely in pairs. Mx1: Endopod distinct from the basipodite and all the lobes bear setae mxp: A specific character with the presence of 3 thickened setae with swollen bases densely covered with spinules; two of these modifued setae are situated on the proximal part of the basipodite and the third, with its tip transformed into a hook and lying across the other two, arises from the distal part of the coxopodite. Exopod 2 and 3 of P3 and P4 not extending distolaterally into outer rounded lobes. Basis of P5 with distolateral outer seta short, not extending beyond distal border of exopodite 3.
