Espèce Paracomantenna profunda - Planche 1 de figures morphologiquesIssued 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.

- Mx2: praecoxal endite with 3 setae; coxal endites with 3 setae; basal endites with 3 setae each, all endites decorated with denticles that are most developed at coxal and proximal basl endites; enditic-like lobe of proximal endiopodal segment with 3 setae, one seta thicker, spine-like; endopod with 6 (1+2+3) setae.
