| | | | | | | Ref.: | | | Markhaseva & Schulz, 2007 (p.732, figs.F) |  issued 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.

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.
