Material examined. AUSTRALIA: TASMAN SEA. Taupo Seamount, 33º 16.85’S 156º 9.15’E, Franklin 05/ 89, St. 8, 244 m, 2 May 1989, J.K. Lowry coll., AM W35530 specimen.
Description. Complete specimen, about 4 mm long, 0.58 mm wide, with 51 chaetigers; all antennae and tentacular and dorsal cirri detached, lost. Body flat, slightly convex on dorsum on anterior part of body. Prostomium rounded, bilobed both anteriorly and posteriorly, with two distinct prostomial lobes. Four eyes in rectangular arrangement. Palps short, ventrally directed, free each other. Cirrophores well developed. Parapodia with digitiform pre- and postchaetal lobes. Ventral cirri digitiform. Chaetae similar throughout body, subdistally slightly enlarged, distally unidentate, with basal spur relatively long, directed almost perpendicular to tip of chaetae; basal spurs of anterior parapodia larger than posterior chaetae ( Figs 6 View FIGURE 6 A, B); some dorsal chaetae of posterior parapodia slightly bidentate ( Fig. 6 View FIGURE 6 B). Anterior parapodia with six chaetae, decreasing progressively to 2–3 on posterior parapodia. Acicula solitary, slender, straight. Pharynx through about six segments, with a crown of 10 soft papillae. Proventricle through 4 segments, with about 32 muscle cell rows.
Remarks. This identification is tentative. The single examined specimen lacks all antennae, tentacular and dorsal cirri, the shape of which (i.e. flat, large, and foliose) is the main diagnostic character of the species, and also we could not observe the trepan. Although the general chaetal shape resembles that of the species, pseudo-compound chaetae appeared to be absent and some chaetae were slightly bidentate distally.
Habitat. Unknown, 82– 244 m.
Distribution. Japan, Australia (? East coast of Australia)
