Ohtsuka & al., 1994 (p.123, Redescr.M, figs.M); Bradford-Grieve,1999 b (p.37, figs.M, figs.170, 189); Ohtsuka & al., 2005 (p.2503: Rem).
Espèce Paraugaptiloides magnus - Planche 1 de figures morphologiquesissued from : J.M. Bradford in N.Z. Jl mar. freshw. Res., 1974, 8 (3). [p.525, Fig.1]. As Paraugaptilus magnus.
Male: a, habitus (dorsal); b, idem (lateral right side); c, rostrum; d, left caudal ramus; e, segments 19-21 of right A1; f, segments 17-19 of left A1; g, A2; h, Md (mandibular palp); i, Mx1; j, P2; k, basipod 2 of P3; l, basipod 2 of P4; m, P5; n, suctorian (large numbers of which attached mainly to segment 18 of left A1).

Nota: This species has several distinctive characters, some of which may eventually necessitate its removal to a new genus.

Scale bars in mm.

Nota: Cephalosome and 1st pedigerous somite separate.
Caudal ramus with seta II-VI well developed.
Left A1 19-segmented.
A2: 1st endopodal segment lacking inner seta, 2nd segment with 2 inner setae of unequal lengths subterminally and 5 setae and 1 setule terminally. Exopod indistinctly 8-segmented, setal formula 0, 1, 1, 1, 1, 1, 0, 3.
Md: gnathobase with 3 cusped teeth, dorsalmost of which bifid at tip; the medial part is damaged and it is not known whether or not a tuft of setules is present; endopod rudimentary, 1-segmented, almost fused with basis, carrying 2 setae of unequal lengths; 1st exopodal segment with well developed seta, 5th segment with non-reduced outer seta.
Mx2: 1st praecoxal endite with 2 setae and 1 vestigial element, 2nd with 2 spinulose setae; basal spine (fig.11F) with 2 rows of spinules; setae on endopod well developed, ornamented with row of long, simple spinules along inner margin (fig.11G)

Male: A, praecoxal arthrite, coxal endite, basal endite and endopod of Mx1 (basal seta indicated by arrowhead); B, 4th to 6th endopod segments of Mxp (innermost seta on 4th and 5th segments indicated by arrowhead); C, inner coxal seta of P4; D, P5 (posterior) (scar of element on 3rd exopod segment of left leg indicated by arrowhead); E, right endopod of P5; F, left endopod of P5; G, inner distal process on 2nd exopod segment of right P5.Scale bars in mm.

Nota: Mx1: praecoxal arthrite with 5 bare spines and 1 shorter process; coxal epipodite with 8 setae; coxal endite with long, spinulose seta; vestigial seta present (indicated by arrowhead); endopod bulbous, 1-segmented, bearing 2 relatively long, spinulose setae terminally.
Mxp: innermost seta on 4th and 5th endopodal segments (indicated by arrowhead) not reduced; seta a on 6th segment reduced; seta b relatively long; setae c and d simply ornamented with spinules along inner margin.
P1 with 2 outer spines on 3rd exopodal segment.
P4 with vestigial element on inner distal angle of coxa.
