Euaugaptilus hulsemannae  Matthews, 1972   (F)
Matthews, 1972 (p.9, 33, Descr.F, figs.F)
Species Euaugaptilus hulsemannae - Plate 1 of morphological figuresissued from : J.B.L. Matthews in Bull. Br. Mus. (Nat. Hist.) Zool., 1972, 24 (1). [p.10, Fig.3].
Female (from 34°S, 85°W): A-B, habitus (lateral and dorsal, respectively); C, Md (biting egge of gnathobase).
A and B to scale I; C to scale II.

Species Euaugaptilus hulsemannae - Plate 2 of morphological figuresissued from : J.B.L. Matthews in Bull. Br. Mus. (Nat. Hist.) Zool., 1972, 24 (1). [p.11, Fig.4].
Female: A, A2; B, Md (mandibular palp); C, Mx1; D, Mx2; E, Mxp; F, P1; G, P2; H, P3; I, P4; J, P5.

Nota: Mx1 is uniramous and whether it is the exopodite or endopodite which has been lost is uncertain; it is thought more likely that the small segment which remains is the endopodite as it lies close to the basipodite setae with a distinct space between it and the exite. In other respects the appendage is well developed with setae on all lobes. Setules are sparsely distributed along the main setae on the exite but are better developed on the inner setae, being particularly dense on the setae of the 1st endite.

N Chile
N: 1
(308) F: 7,4; {F: 7,40}
Rem.: bathy-abyssopelagic. Depth between 2000 and 3000 m (Matthews, 1972).
For Matthews (1972, p.12) this species is similar to E. farrani but is distinguished from it by the absence of the exopodite on Mx1 (a diagnostic character) and by an unreduced number of spines on P1. It is also similar to E. distinctus, being distinguished by complete segmentation of P1, and to E. elongatus and E. hyperboreus from both of which it is easily recognized by the much broader prosome.

In ''squamatus" Group after Matthews (1972, p.64) {See remarks in Euaugaptilus genus}.
