Material examined

Three males (two dissected), one ovigerous female, SAM A17820 . One female, SAM A39991 . One male, one female, NMV J47037 .

Diagnosis

Eyes colourless. Dorsum irregularly tuberculate, especially on transverse ridges, without dominant spines. Pereonites 2 and 3 of female with triangular lateral wings (obsolete in male); pereopods 4–7 and pleonites without lateral wings. Pleotelson apex obtuse, not apically produced as spine, posterolateral margins with well-defined triangular angular flanges. Male pleonite 2 strongly elevated as paired dorsolateral bosses, pleonite 3 with lower dorsomedial boss. Posteroventral margin of pereonite 4 of male deeply incised, with pair of tubercles on margin. Male to 6.5 mm; female

to 7.0 mm.

Remarks

Poore (1991) and Kensley (1978a, 1984) illustrated the setulose lobe of the male pleopod 1 endopod of N. oudops with an anterior row of teeth-like short setae. These seem not to be universally present in this species and an alternative figure is given here (figure 10, PL 1). The confusion of this species with N. kensleyi n. sp. was discussed by Poore (1991) and above where the new species is described. The species occurs off KwaZulu-Natal, South Africa, at 650–1510 m depth.
