(Figs. 2–3)

Type material Holotype, adult female, collected on March 23, 2005 in the Guinea Basin at DIVA Station M 63/2 98, position 00°37′12″N, 006°28′06″W, from mud at 5,165 to 5,174 m depth; mounted in Fluoromount-G®; and deposited at the Museum für Naturkunde (Berlin, Germany) under accession number ZMB 11521 . No additional specimens were available.

Diagnosis Pycnophyes with middorsal processes on segments 1–10 and paradorsal intracuticular atria on segments 1–9; middorsal processes of similar size until segment 7 and, from this point, turning progressively longer towards the posterior trunk segments; middorsal process on segment 10 extending over segment 11; pairs of paradorsal setae on segment 1 only, laterodorsal setae on segments 2–9, paralateral setae on segment 1, lateroventral setae on segments 2, 4, 6, 8, and 10 (two pairs); ventrolateral setae on segments 1 and 5 and ventromedial setae on segments 2–9; and one pair of horn-shaped cuticular extensions on segment 11.

Etymology The species name, nubilis , is Latin for “marriageable” and refers to the female nature of the holotype and the lack of known male specimens.
