Species Xantharus renatehaassae - Plate 1 of morphological figuresissued from : K. Schulz in Helgoland. Meeres., 1998, 52. [p.44, Fig.1].
Female (from 74°36'.2S, 27°15.8'W): A, habitus (dorsal); B, idem (lateral left side) (A1 damaged); C, rostrum (ventrofrontal); D, idem (lateral); E, urosome (ventral); F, genital degment (lateral left side); G, A2.

Nota: Cephalosome and 1st pediger fused, 4th and 5th fused.
- A1 slightly asymmetrical (probably caused by previous regeneration following damage to distal segments of right side); left A1 24-segmented, extending to middle of 2nd pediger. - Anal somite very short.


Species Xantharus renatehaassae - Plate 2 of morphological figuresissued from : K. Schulz in Helgoland. Meeres., 1998, 52. [p.45, Fig.2].
Female: A, A1 (segments 1-10); A', idem (segments 11-24); B, Md; C, Md (masticatory edge); D, Mx1; E, Mxp (ae = aesthetasc); E', aesthetasc of coxal endite 3 of Mxp.

Nota: Mx1 with arthrite of praecoxa with 9 large spines plus 1 slender seta and 3 posterior setae; endite and epipodite of coxa with 2 and 9 setae, respectively; proximal and distal endites of basis each with 4 setae; endopod fused to basis with 3, 3, 5 setae; exopod with 8 setae.


Species Xantharus renatehaassae - Plate 3 of morphological figuresissued from : K. Schulz in Helgoland. Meeres., 1998, 52. [p.46, Fig.3].
Female: A, Mx2 (armature of endopod not entirely shown); A', Mx2 (endopod); B, P1 (anterior); C, P2 (posterior); D, P3 (posterior); E, P4 (posterior); F, P5 (posterior) (left partly detached).
