Rythabis heptneri Markhaseva & Ferrari, 2005 (F) | |
| | | | | | | Ref.: | | | Markhaseva & Ferrari, 2005 a (p.149, Descr.F, figs.F, Rem.) |  issued from : E.L. Markhaseva & F.D. Ferrari in Invert. Zool., 2005, 2 (2). [p.150, Fig.24]. Female from (from Kona Island, Hawai): A, habitus (lateral); B, posterior prosome and urosome (lateral, right side); C, urosome (dorsal); D, genital complex (lateral, left side); E, idem (ventral); F, forehead (lateral); G, P5 (posterior). Scale bars: 0.1 mm. Nota : A1 broken. Prosome 3.5 times longer than urosome (excluding caudal rami ). Cephalosome and pediger segment 1 separate, 4th and 5th separate. Posterior corners of prosome rounded laterally. Genital complex narrowing slightly at midlength ; asymmetrical with bump on right slightly more pronounced that bump on left. Rostrum without filaments. P5 3-segmented, distal segment (exopod) with a long medial, 1 short lateral and 1 short subterminal setae, and 1 terminal attenuation.

 issued from : E.L. Markhaseva & F.D. Ferrari in Invert. Zool., 2005, 2 (2). [p.151, Fig.25]. Female: forehead (ventral); B, A2 (protopod and endopod); C, A2 (exopod: 4 proximal segments); D, Md (gnathobase; posterior); E, Md (mandibular palp); F, Mx1; G, Mx2; H, Mxp (syncoxa); I, P1 (anterior). Scale bars: 0.1 mm. Nota : A2 : coxa with 1 seta ; basis with 2 setae ; endopod 2-segmented, proximal segment with 1 seta, setae missing from distal segment ; Only 4 segments retained on exopod, setae lost. Md : gnathobase with 6 teeth and 1 seta ; endopod 2-segmented, proximal segment with 2 setae, distal with 9 setae ; exopod with 1, 1, 1, 2 setae. Mx1 : praecoxal endite with 10 terminal and 4 posterior setae ; coxal endite with 4 setae, coxal epipodite with 9 setae ; proximal basal endite with 4 setae, distal basal endite fused to endopod, setae of distal basal endite indistinguishable from those of endopod, 11 setae total ; exopod with 4 setae. Mx2 : proximal praecoxal endite with 4 setae, distal with 3 setae, 1 recurved ; proximal and distal coxal endite with 3 setae, 1 recurved on each endite ; proximal basal endite with 4 setae, 1 thick, 1 worm-like ; distal basal endite + ramus with 4 worm-like and 4 brush-like (2 short, thick brush-like and 2 longer, thin brush-like) setae.Mxp : setae on praecoxal endites of syncoxa not well-separated, with 1 (worm-like seta), 2 (1 worm-like seta), 2 (1 worm-like seta) ; coxal endite with 3 setae ; basis and endopod lost. P1 : coxa without seta ; basis with medial seta ; exopod 3-segmented ; endopod 1-segmented with 3 medial and 2 terminal setae ; Von Vaupel Klein’s organ with basal seta curved around anterior face of endopod ; endopod without anterior knob or denticles.
