| | | | | | | Ref.: | | | Markhaseva & Renz, 2015 (p.1034, Descr.F, figs.F) |  Issued from : E.L. Markhaseva & J. Renz in Crustaceana, 2015, 88 (9). [p.1035, Fig.1]. Female (from 29°19'N, 28°38'W): A-B, habitus (dorsal and lateral, respectively); C, anterior cephalosome (lateral); D, rostrum (ventral view); E-F, posterior prosome and urosome (dorsal and lateral, respectively); G, posterior prosome and genital double-somite (ventral); H, spermathecae (lateral view); I, caudal rami (ventral); J, P5 (vntral view); . Md : mandible; Prgn: paragnaths; Mx2: maxilla. Scale bars: A-B, 0.5 mm; C-J, 0.1 mm. Nota: - Rostrum as round-triangular projection bearing 2 filaments. - Cephalosome and pedigers 1-5 separate. - posterior corners of pediger 5 obtuse-triangular in dorsal view and rounded in lateral view. - Spermathecae elongate, directed anteriorly distally. - Caudal rami with 6 setae (4 terminal, 1 small ventral, scar of broken lateral seta present). - P5 uniramous, 3-segmented ; 3rd left segment with 3 terminal and right with 2 terminal spines.

Female: A, A2; B, A2 exopod, different view, proximal segment is not figured; C, D and E, Mx2 in different views (endite setation is not figured in D). Enp: endopod; p: praecoxal endite; c: coxal endite; bp: basal proximal endite; bd: basal distal endite; abd: attenuation of basal distal endite; el: enditic-like lobe of proximal endopodal segment. Scale bars: 0.1 mm. Nota : - A2 coxa, basis and endopod segment 1 with 1 seta each, endopod segment 2 with 13 setae ; exopod with 1, 1-1-1, 1, 1, 1, 1, 0, and 3 setae. - Mx2 praecoxal endite with 4 setae, coxal endite with 3 setae ; proximal basal endite with 2 setae, distal endite’s inner part transformed into large spine-like attenuation with 1 seta proximally and, enditic-like lobe of proximal endopodal segment with 2 setae ; endopod with 3 setae. Praecoxal to basal endites with distal part flat and round, its surface in coxal and basal endites is densely covered by short spinules, brushlike.
