Ref.:
Markhaseva & Ferrari, 2005 a (p.152, Descr.F, figs.F, Rem.)
Species Rythabis schulzi - Plate 1 of morphological figuresissued from : E.L. Markhaseva & F.D. Ferrari in Invert. Zool., 2005, 2 (2). [p.153, Fig.26].
Female (from 13°23'N, 102°27'W): A, posterior prosome and urosome (lateral, right side); B, genital complex (lateral, right side); C, idem (ventral).
Scale bars: 0.1 mm.

Nota : Prosome 2.75 times longer than urosome. Cephalosome and pediger segment 1 separate, 4th and 5th separate. Posterior corners of prosome rounded laterally. Genital complex symmetrical in ventral view ; with a ventral anterior and posterior bump in lateral view. A1 24-segmented. A2 : coxa with 1 seta ; basis with 2 setae ; endopod 2-segmented, proximal segment with 1 seta, distal segment with 7 setae on subterminal lobe ; exopod 7-segmented with 1, 1, 1, 1, 1, 1, 3 setae. Md : gnathobase with 6 well-developed teeth and 1 seta ; basis with 2 setae ; endopod 2-segmented, proximal segment with 2 setae, distal with 9 setae ; exopod with 1, 1, 1, 1, 2 setae. Caudal ramus with 4 large, thick terminal setae, 1 small dorsal seta and 1 small medial ventral seta.


Species Rythabis schulzi - Plate 2 of morphological figuresissued from : E.L. Markhaseva & F.D. Ferrari in Invert. Zool., 2005, 2 (2). [p.154, Fig.27].
Female: A, Mx2 (praecoxa and coxa); B, Mx2 (basis and ramus); C, Mxp (syncoxa); D, Mxp (basis and endopod).
Scale bars: 0.1 mm.

Nota : Mx2 : proximal praecoxal endite with 4 setae, distal with 3 setae ; proximal coxal endite with 3 setae, distal with 3 setae ; proximal basal endite with 4 setae, 1 thick and straight, and 1 worm-like, distal basal endite + ramus with 6 worm-like setae (3 shorter and 3 longer) and 2 brush-like setae. Mxp : syncoxa with several areas of denticles anteriorly ; groups of setae on praecoxal endites of syncoxa not well-separated, with 1 (worm-like seta), 2 (1 worm-like seta), 2 (1 brush-like seta) ; coxal endite with 3 setae in the middle and 2 setae distally ; endopod with 4, 4, 3, 3 + 1, and 4 setae.


Species Rythabis schulzi - Plate 3 of morphological figuresissued from : E.L. Markhaseva & F.D. Ferrari in Invert. Zool., 2005, 2 (2). [p.155, Fig.28].
Female: A, Mx1; B, P1 (anterior); C, P1 (distal section of basis and endopod; anterior); D, P3 (posterior); E, P4; F, P5 (distal segment of exopod).
Scale bars: 0.1 mm.

Nota : Mx1 : praecoxal endite with 9 terminal and 4 posterior setae ; coxal endite with 5 setae, coxal epipodite with 9 setae ; proximal basal endite with 4 setae, distal basal endite fused to endopod with groups of 4 and 9 setae ; exopod with 5 setae. P1 : coxa without seta ; basis with medial seta ; exopod 3-segmented ; endopod 1-segmented with 3 medial and 2 terminal setae ; organ of Von Vaupel Kein as curved basal seta and anterior knob of endopod with proximal denticles.
