Espèce Brodskius abyssalis - Planche 1 de figures morphologiquesissued from : E.L. Markhaseva & K. Schulz in J. Nat. Hist., 2007, 41 (13-16). [p.733, Fig.1]
Female (from 67°31'S, 0°01'E): A-B, habitus (dorsal and lateral, respectively); C-D, forehead (lateral and ventral, respectively); E, posterior prosome and urosome (left lateral); F, urosome (dorsal; left dorsal seta detached); G, genital double-somite (left lateral); H, idem (right lateral); I, idem (ventral); J, anal somite and caudal rami (ventral); K, A1; L, P5 (posterior).
Scale bars: 0.1 mm.

Nota : Prosome 4.1 times longer than urosome. Rostrum without filaments. Cephalosome and pediger 1 incompletely separate, 4th and 5th separate. Posterior corners significantly indented in lateral view. Spermathecae oblong-round. Caudal rami with 4 terminal, 1 small dorsal and 1 small ventral setae. A1 24-segmented slightly longer than prosome. P5 uniramous, 3-segmented ; coxae naked and fused by intercoxal sclerite ; basis with small patch of denticles distolaterally ; exopod with denticles on posterior surface, 1 short lateral, 1 moderately long subterminal spine, 1 long terminal unarticulated extension, and 1 long medial spine, all toothed.


Espèce Brodskius abyssalis - Planche 2 de figures morphologiquesissued from : E.L. Markhaseva & K. Schulz in J. Nat. Hist., 2007, 41 (13-16). [p.734, Fig.2]
Female: A, A2; B, Mxp; C, P2 (posterior); D, P3 (posterior); E, P4 (posterior, endopod and exopod incomplete).
Scale bars: 0.1 mm.

Nota : A2 : endopodal segment 1 with 1 seta, 2nd segment with 12 setae ; exopod 7-segmented with 0 , 2, 1, 1, 1, 1, and 3 setae. Mxp : syncoxa without seta on proximal praecoxal endite, 2 setae on middle endite, 3 setae on distal endite ; coxal endite with 3 setae ; basis with 3 medial, 2 distal setae and row of denticles proximally ; endopod of 5 segments with 4, 3, 2, 2+1 and 4 setae.


Espèce Brodskius abyssalis - Planche 3 de figures morphologiquesissued from : E.L. Markhaseva & K. Schulz in J. Nat. Hist., 2007, 41 (13-16). [p.735, Fig.3]
Female: A, Md (mandibular palp); B, Md (gnathobase); C, Mx1; D, Mx2 (praecoxal and coxal endites); E, Mx2 (proximal basal endite and distal basal endite fused to endopod); F, P1 (anterior).
Scale bars: 0.1 mm.

Nota : Md gnathobase elongate, narrow, cutting edge narrow with deep incision ; exopod 5-segmented with 1, 1, 1, 1, and 1 seta ; endopod segment 1 with 1 seta, segment 2 with 9 setae ; basis with 1 seta. Mx1 : praecoxal endite with 9 terminal and 2 posterior setae ; coxal endite with 2 setae, coxal epipodite with 6 setae ; proximalbasal endite with 4 setae (1 longer and thicker than others and heavily setulated) ; distal basal endite fused to endopod with 10 setae in total (2 longer and thicker than others and heavily setulated) ; exopod with 6 setae. Mx2 : proximal praecoxal endite with 4 setae, distal with 3 setae ; proximal and distal coxal endites with 3 setae each ; proximal basal endite with 4 setae (1 thicker than others, 1 poorly sclerotized) ; distal basal endite plus endopod with 8 sensory setae (5 worm-like and 3 brush-like (tips of worm-like sensory setae thread-like, 1 of brush-like setae thicker than others). P1 : basis with tiny distolateral seta and medial distal seta moderately curved ; endopod 1-segmented with 3 medial and 2 terminal setae and small denticles along lateral edge distally, lateral lobe poorly developed, triangular.
