Neoscolecithrix sp.  Bradford, 1973   (F, Juv.5 F)
Ref.:
Bradford, 1973 (p.147, figs. juv.V F); Bradford & al., 1983 (p.124, figs. Juv.5); Hulsemann, 1985 (p.60, 61, Rem.); Bradford-Grieve, 2001 a (p.782, figs.F, Rem.)
Espèce Neoscolecithrix sp. - Planche 1 de figures morphologiquesissued from : K. Hulsemann in Polar Biol., 1985, 5. [p.61, Table 2].
Selected characters in females. B = basipod; Ri = endopod; Re = exopod; + data from immature specimen.


Espèce Neoscolecithrix sp. - Planche 2 de figures morphologiquesissued from : J.M. Bradford-Grieve in N. Z. J. mar. Freshw. Res., 2001, 35. [p.783, Fig.1]. As Neoscolecithrix Cf. magna.
Female (from 41°04.67'S, 176°23.48'): A-B, habitus (dorsal and lateral, respectively); C, rostrum (lateral); D, rostrum (posterior); E, urosome (ventral); F, urosome (right side; G, caudal ramus (ventral); H, idem (dorsal); I, P5 (anterior view); J, right terminal segment of P5 (posterior view).

Nota: Head and pedigerous somite 1 fused, 4 and 5 separated. Genital double somite and following 2 somites apparently covered in large, rounded scales (presence of these in many cases inferred from small attachment location as many scales had apparently dropped off). Urosomite 3 (abdominal segment 2) and urosomite 4 (abdominal segment 3) posterior borders fringed with rounded scales. Anal somite small, appears to be fused with caudal rami dorsally


Espèce Neoscolecithrix sp. - Planche 3 de figures morphologiquesissued from : J.M. Bradford-Grieve in N. Z. J. mar. Freshw. Res., 2001, 35. [p.784, Fig.2]. As Neoscolecithrix Cf. magna.
Female: A, A1; B, A2; C, Md (gnathobase); D, Md (masticatory edge); E, Md (mandibular palp); F, Mx1; G, left Mx2; H, terminal part of right Mx2.

Nota: A1 24-segmented, extending to posterior border of pedigerous somite 3. A2 endopod just greater than half length of exopod; coxa and basis separate; endopod 2-segmented; exopod 4-segmented. Mx1 praecoxal arthrite with 4 posterior surface setae as well as 10 marginal spines and setae; coxal endite and basal endites 1 and 2 with 3, 4, 5 setae respectively; basis and endopod segments fused; endopod with 3 + 7 setae; exopod with 10 setae; basal exite without seta; coxal epipodite with 9 setae. Mx2 praecoxa with an outer distal protrusion; 5 endites; endopod with 5 very long, wide, worm-like sensory setae on both sides and 3 shorter, brush-like sensory setae on right and 2 brush-like and 1 very short (brush-like ?) sensory seta on left.

Female: A, right Mxp (coxa flattened); B, left praecoxa and coxa of Mxp; C, detail of setation of coxal endite 2; D, P1 (anterior view); E, P2 (posterior); F, right basis of P2 (posterior); G, P3 (posterior); H, P4 (posterior).
