Figures

Plate 1 issued from : K. Schulz in Mitt. Hamb. Zool. Mus. Inst., 2005, 102. [p.58, Fig.4 B-G].
Female (from E Weddell Sea): B, habitus (lateral left side); C, idem (dorsal); D, urosome (ventral); E, idem and 5th pediger somite (lateral right side); F, rostrum (ventral).
Scale bars = 0.050 mm.
Plate 2 issued from : K. Schulz in Mitt. Hamb. Zool. Mus. Inst., 2005, 102. [p.61, Fig.5].
Female: A, A1 (segments 1-12 = ancestral I-XV); B, idem (segments 13-24 = ancestral XVI-XXVIII); C, A2; D, Md; E, Md (masticatory edge); F, P5 (posterior).
Scale bars = 0.050 mm.
Plate 3 issued from : K. Schulz in Mitt. Hamb. Zool. Mus. Inst., 2005, 102. [p.62, Fig.6].
Female: A, Mx1 (anterior); B, Mx1 (praecoxal arthrite, posterior); C, Mx2 (endopod omitted); D, Mx2 (endopod); E, Mxp.
Scale bars = 0.050 mm.
Nota: Praecoxal arthrite of Mx1 with 9 marginal setae and 3 slender posterior setae; coxal epipodite with 7 large and 2 smaller setae, coxal endite and 1st basal endite bearing 2 and 4 setae, 2nd basal endite with 4 setae; basis separate from endopod (endopod unsegmented) with 2 and 5 setae; exopod with 7 setae.

Male: A, habitus (dorsal); B, idem (lateral left side); C, rostrum (ventral); D, P5 (anterior).
Scale bars = 0.050 mm.
Nota: Cephalosome and 1st pediger somite incompletely fused (trace of line dorsally), 4th and 5th separate except lateroventral margin. A1 slightly asymmetrical, left 19-segmented and right 18-segmented; aesthetascs very long. Minute anal somite telescoped within preceding somite.

Scale bars = 0.050 mm.
Nota: Md, Mx1, Mx2 and P1-P4 similar to those of female. Mxp with 3 smaller sclerotized setae distally, 1 short brush-like sensory seta at mid-length with a basket-like head, 1 spinulose and 1 long vermiform sensory setae submedially, and 1 long vermiform sensory seta at the base.

Remarks

hyperbenthic (Depth: 1535-1573 m).
Schulz (2005, p.69) points out the species deviates from congeners in that it has an arrangement of 4 vermiform plus 4 brush-like sensory filaments on the endopod of Mx2 in both seses which is untypical of any of the remaining scolecitrichids, except Racovitzanus antarcticus Giesbrecht (1902), as redescribed by Park (1983).
