The new species is most easily distinguished from N. oudops in lacking angles on the posterolateral margins of the pleotelson. The transverse ridges which dominate each pereonite are evenly and finely tuberculate whereas in N. oudops they bear pairs of larger tubercles among the smaller ones. All preserved specimens are clear white while those of N. oudops are muddy yellow. Both have colourless eyes.</p> <p>Neoarcturus kensleyi co-occurs with N. oudops and is known from only two localities off KwaZulu-Natal to Transkei, eastern South Africa, and the Cape area, south-western South Africa, at 680 and 1400 m depth.</p> </div>	https://treatment.plazi.org/id/DC5987CB8F69AE4A325BFAFDFC18BF5B	Public Domain	No known copyright restrictions apply.

Park and Wägele (1995) redescribed the holotype female and discussed the differences between Rectarcturus Schultz, 1981, of which this is the type species, and Neoarcturus. Unfortunately their discussion treated species of Neoarcturus, Austroarcturus and Fissarcturus synonymously. They realized the differences between Brandt’s (1990) species (referred here to Fissarcturus) and holidoteids (see discussion under Neoarcturus above), and that Rectarcturus is closer to Fissarcturus than to Neoarcturus s. s. Significant differences are that the groove on the male pleopod 1 endopod opens distolaterally in Rectarcturus (not laterally as in Fissarcturus), there are no paired pleotelsonic spines, pereopods 5–7 lack robust setae on the posterior margin of carpus and propodus, and the unguis of pereopods 2–4 is shorter than the body of this article (longer and setiform in Fissarcturus).</p> </div>	https://treatment.plazi.org/id/DC5987CB8F5CAE7A3264FBFCFC4BBC83	Public Domain	No known copyright restrictions apply.
