| | | | | | | Syn.: | Unidentified sp.B Harding, 1966 (p.: 17, figs. F: p.36, 37) | | | | Ref.: | | | Markhaseva & Kosobokova, 2001 (p.321,Descr. F, figs.F) |  issued from : E.L. Markhaseva & K.N. Kosobokova in Sarsia, 2001, 86. [p.320, Figs.1-7]. Female (from 81°13'N, 106°34'E): 1-2, habitus (right lateral and dorsal, respectively); 3, pedigerous segments 4-5 and urosome (right lateral); 4, urosome (dorsal); 5, A1 (segments 1-8); 6, A1 (segments 9-16); 7, A1 (segments 17-24). Scale bars: 0.1 mm. Nota : Rostrum absent. Cephalosome and pediger somite 1 incompletely separate, 4th and 5th separate. Prosome : Urosome ratio 1.3 : 1. Posterior corners of pedigerous somite 5 as short lobes. A1 24-segmented, reaching posterior border of pediger somite 2. Genital somite symmetrical.

 issued from : E.L. Markhaseva & K.N. Kosobokova in Sarsia, 2001, 86. [p.321, Figs.8-13]. Female (right limb, by dotted line-additions after left limb): 8, A2; 9, Md (mandibular palp); 10, Md (gnathobase); 11, Mx1; 12, Mx2; 13, Mxp. Scale bars: 0.1 mm. Nota : A2 exopod incompletely 8-segmented, exopodite 2-3 are partly fused, segments 1-3 lacking setae Praecoxal arthrite (1st inner lobe of Mx1 with 10 terminal spines, 1 anterior and 1 posterior seta ; coxal endite ( (2nd inner lobe) with 1 seta ; basal endites (3rd lobe) with 2 setae, (4th lobe) without setae) ; endopod rudimentary with 4 setae ; exopod with 9 setae.

Distribution map of Arctokonstantinus hardingi by geographical zones
|
| | | | Loc: | | | Arct. (E Nansen Basin) | | | | N: | 3 | | | | Lg.: | | | (840) F: 4,1; {F: 4,1} | | | | Rem.: | bathypelagic (3000-1000 m).
According to Markhaseva & Kosobokova (2001, p.323): considering the mouth-part morphology, this species could be considered a predator: Mx1 with strongly developed praecoxal arthrite (1st lobe). Mx2 highly specialized with inner lobes 2-3 bearing short flat spines and inner lobes 4 and 5 transformed into spine-like attenuations with the distal part of the limb heavily strengthened. Mxp with basis and endopod segments well developed, endopod segments with strong setae poorly setuled. Md gnathobase with 4 well developed teeth. | | | Last update : 20/03/2015 | |
