Ref.:
Markhaseva & Schulz, 2008 (p.44, descr.F, figs.F)
Species Pseudotharybis polaris - Plate 1 of morphological figuresissued from : E.L. Markhaseva & K. Schulz in Mitt. hamb. zool. Mus. Inst., 2008, 105. [p.45, Fig.9].
Female (from 59°40'S, 57°35'W): A-B, habitus (dorsal and lateral, respectively); C-D, rostrum (dorsal and ventral views, respectively); E, urosome (dorsal); F, genital double-somite (ventral); G, anal somite and caudal rami (ventral); H, A1 1-9th (I-XI ancestral) segments; J, right P5.
Scale bars: 0.5 mm (A-B); 0.1 mm (C-J).

Nota : Rostrum a plate subdivided distally into 2 obtusely rounded short lobes. A1 broken (only 9 segments retained). Cephalosome and pediger 1 and pedigers 4 and 5 incompletely separate. Caudal rami with 4 terminal setae, 1 ventral and 1 subterminal seta. P5 uniramous, 3-segmented ; right segment 3 (exopod) with 3 spines ; left leg in poor condition.

Nota : A2 coxa with 1 seta (broken), basis with 2 setae ; exopod with 1, 2, 1 (broken), 1, 1, 1, 1 and 3 setae ; exopod 1.2 times as long as endopod ; 1st endopodal segment with 2 setae, 2nd with 8 and 6 setae. Md exopod 5-segmented, about as long as endopod, with 1, 1, 1, 1 and 2 setae ; endopod 2-segmented (segment 1 with 3 setae, segment 2 with 9 setae). Mx1 praecoxal arthrite with 9 terminal, 4 posterior, 1 small setae and small attenuation ; coxal endite with 4 setae ; proximal basal endite with 4 setae ; distal basal endite with 5 setae ; endopod segments fused with 16 setae ; exopod with 11 setae ; coxal epipodite with 9 setae.
