| | | | | | | Ref.: | | | Markhaseva & Renz, 2019 (p.214, Descr. F, figs.F, Rem.) |  Issued from : E.L. Markhaseva & J. Renz in Arthropoda Selecta, 2019, 28 (2). [p.216, Fig.1]. Female (from Kurile-Kamchatka Trench): A-B, habitus (dorsal and lateral); C, cephalosome (lateral); D, posterior prosome and urosome (dorsal); E, posterior prosome and genital double-somite (lateral); F, genital field (ventral); G, A1 (dotted line marks additions after another holotype limb; star marks aesthetasc). Scale bars: 0.5 mm (A-B); 0.1 mm (C-G). Nota: - Prosome 3.3-4.2 times as long as urosome. - Rostrum absent. - Cephalosome and pediger 1 incompletely separate, 4th and 5th pedigers completely separate. Posterior corners of prosome in dorsal view triangular; in lateral view pointed, directed dorsally. - Urosome 4-segmented. - Spermathecae upturned anteriorly, shape variying. - Corners' shape of posterior prosome and genital double-somite slightly variying according to the specimen's localisation (from Kurile-Kamchatka, Brazil, Angola and N Atlantic. - A1 24-segmented, reaching 3rd pedigerous somite, or exceeding to somites 4-5.

Distribution map of Paracomantenna profunda by geographical zones
|
| | | | | | | Loc: | | | Kurile-Kamchatka Trench, Angola Basin, Brazil Basin, Off S Cape Verde (10°42.89'N, 25°03.21'W), Weddel Sea (65°19.20'S, 48°03.81'W);
Type locality: 46°14.77' N, 155°32.79' E. | | | | N: | 1 | | | | Lg.: | | | (1249) F: 1,40-1,70; {F: 1,40-1,70} | | | | Rem.: | Abyssal, above sea bed. More or less 5000 m depth.
For Markhaseva & Renz (2019, p.220) , specimens of the new species show slight variability in the setatiopon of Mx1, P1 endopod ornamentation, in the segmentation of A2 exopod and Mxp endopod., also according to the localisation. | | | Last update : 19/06/2023 | |
