Pl. 109). <b>Material Examined</b>. <i>Monowai Seamount</i>: 1 female, 10.0 mm x 8.4 mm, 27°12.51'S 177°26.02'E, rock dredge, <i>Tangaroa</i>, stn TAN0411/32, 252– 403m, 7 Oct. 2004. (NIWA 48574) <b>Comparative Material.</b> <i>Fiji</i>: 1 male, 13.5 mm x 11.4 mm, 18°18.4' S, 178°02.5' E, 233–248 m, MUSORSTOM 10, DW1377, 17 Aug. 1998. <b>Remarks</b>. <i>Dynomene pilumnoides</i> is the second dynomenid species discovered in New Zealand. <i>D. pilumnoides</i> can be separated from the other dynomenid species, <i>Metadynomene tanensis</i>, by virtue of its 4 sub-acute anterolateral teeth (versus 3 blunt teeth) and the short plumose setae, interspersed with clumps of longer filiform setae, on its carapace (versus short soft setae all about the same length). Species of <i>Dynomene</i> are for the most part found in shallow water, occurring from the intertidal to 100 m. <i>D. pilumnoides</i> has the greatest depth range, 18–400 m, and it has been collected from rocky bottoms covered in <i>Lithothamnion</i> (Rhodophyta), sponges and corals. The specimen of <i>D. pilumnoides</i> was taken with a rock dredge that also caught <i>Cheiraster</i> sp. (Asteroides), <i>Bathymodiolus</i> sp. and <i>Branchipolynoe</i> sp. (Polychaeta) in other nearby samples. The Monowai Seamount is part of the Kermadec volcanic system. The specimen (Fig. 3b) collected during the MUSORSTOM 10 expedition is a new record for Fiji. The seven species of <i>Dynomene</i> can be identified using the key provided by McLay (2001: 810). <b>Geographical Distribution</b> <i>D. pilumnoides</i> has a wide Indo-West Pacific distribution that includes Madagascar, Réunion, Australia, Indonesia, Philippines, Japan, Hawaiian Is, New Caledonia, and now Fiji and the Monowai Seamount, New Zealand. Depth range is 18–403m although most records come from 100–300m.
