Female (from E Weddell Sea): A, habitus (dorsal); B, idem (lateral right side); C, genital segment (ventral); D, idem (lateral right side); E, rostrum; F, caudal rami (ventral); G, A2; H, Md (masticatory blade); I, Md (mandibular palp); K, Mx2 ( (endopodal armature incomplete); L, Mx2 (basal endite); M, Mx2 (terminal part).

Nota: Rostrum robust, bifurcate with short diverging points without filaments.


Espèce Parabradyidius angelikae - Planche 2 de figures morphologiquesissued from : K. Schulz & E.L. Markhaseva in Mitt. hamb. zool. Mus. Inst., 2000, 97. [p.80, Fig.2].
Female: A, A1 (ancestral segments 1 to XV); B, idem (ancestral segments XVI to XXIV); C, idem ( segments XXV to XXVIII); D, Mx1 (armature omitted); D1, Mx1 (praecoxal arthrite); D2, Mx1 (coxal epipodite); D3, Mx1 (coxal endite); D4, Mx1 (1st basal endite; D5, Mx1 (2nd basal endite; D6, Mx1 (endopod); D7, Mx1 (exopod); E, P5; F, P5 (anterior, variation).

Nota: A1 (24-segmented) reaching to posterior end of genital segment.
- Mx1: praecoxal arthrite with 9 spiniform, 4 posterior and 1 anterior setae; coxal epipodite with 7 strong and 2 shorter setae; coxal endite with 5 setae; 1st and 2nd basal endites with 4 and 5 setae, respectively; endopodal segments mostly fused and armed with 15 unequal setae; exopod with 11 setae.
- P5 uniramous, 3-segmented; coxa fused to intercoxal sclerite; basis globular and unarmed; 3rd segment very small bearing 1 outer proximal and 1 distal spine accompanied by 1 spine-like point incorporated basally to segment. A single paratype (body length 5.70 mm) was different (Fig.2F): 2nd segment (basis) on right side distinctly larger than on left, with small inner hook proximally on right; small remnants of endopodal buds mediodistally on both sides ornamented with setules; 3rd segment (1st exopodal segment) distinctly larger than in holotype and remaining specimens bearing 1 outer and 1 terminal spine; terminal spine accompanied by spine-like point.

Female: A, Mxp (syncoxa); B, Mxp (fused 1st endopod segment and distal part of endopod); D, P1 (anterior); E, P2 (posterior).

Female: B, P3 (posterior); C, P4 (posterior).

Male: D, habitus (lateral right side); E, Md; F, Mx1.

Nota: A1 (24-segmented on left and 23-segmented on right side) extending to 3rd pediger somite; Md with coxa small lacking any gnathobase (masticatory blade).. mx1 reduced, small; praecoxal arthrite with small, curled setae; coxal and basal endites with about 5, 4, and 5 small setae; exopod large with 11 setae; coxal epipodite unarmed.


Espèce Parabradyidius angelikae - Planche 5 de figures morphologiquesissued from : K. Schulz & E.L. Markhaseva in Mitt. hamb. zool. Mus. Inst., 2000, 97. [p.79, Fig.1].

Coxa of left leg about double width of right one; basis indistinctly 2-segmented, rod-like endopod inserted subdistally; exopod indistinctly 3-segmented; distal (3rd) segment short, mostly fused to curved exopodal segment 2 and armed with inner row of spinules increasing in length distally; straight digitate process tapering to blunt tip and furnished with set of small spinules directed medially.
