Figure 17 View FIGURE 17

Naineris victoriae Day, 1977: 238–239 , fig. 3k–p.

Material examined. Victoria: Westernport Bay , 38°22’S, 145°32’E, 22.11.1973, depth 9 m, coll. Fisheries & Wildlife (Melbourne), Holotype, AM W.7358; 09.01.1974, depth 12 m, AM W.7359, paratypes, 2 specimens from same location. GoogleMaps

Type locality. Westernport Bay , Victoria .

Description. All specimens incomplete, thoracic width 1.7– 2 mm. Body slightly flattened in thorax, cylindrical in abdomen ( Fig. 17A View FIGURE 17 , C–E). Prostomium conical with round tip ( Fig. 17 View FIGURE 17 С– E). Thoracic chaetigers number-

ing 16–20, transition to abdomen indistinct ( Fig. 17A View FIGURE 17 ). Branchiae lost in all specimens, presumably starting from chaetigers 8–9 where scars seen ( Fig. 17D, E View FIGURE 17 ). Thoracic notopodial postchaetal lobes developed from first chaetiger, rapidly increasing in size, from digitate to foliaceous; in abdomen becoming long and narrow ( Fig. 17B View FIGURE 17 , С–E, H, J). Thoracic neuropodial postchaetal lobes mammiform with one podal papillae situated in middle of lobe ( Fig. 17A, B, F, G, H, J View FIGURE 17 ). In holotype neuropodia of chaetiger 14 bearing two podal papillae on one side of worm ( Fig. 17G View FIGURE 17 ). Interramal cirrus developed on last thoracic and abdominal chaetigers; in abdomen becoming longer than neuropodia ( Fig. 17B, J, K View FIGURE 17 ). Abdominal neuropodia simple, triangular with tips forming papillae ( Fig. 17K View FIGURE 17 ). No subpodal flange, subpodal, stomach, or flange papillae. Notopodial chaetae crenulate capillaries; thoracic neuropodia bearing capillaries and thin curved serrated uncini in lower part of anterior row ( Fig. 17F, H, I View FIGURE 17 ). Both rami supported by straight aciculae in abdomen; in neuropodia aciculae emergent, with curved bidentate tips ( Fig. 17J, K, L View FIGURE 17 ).

Distribution. Australia, Victoria.

Habitat. Upper subtidal.

Remarks. Naineris victoriae differs from the other species of the genus by having interramal cirri and projecting bidentate neuropodial aciculae. The other unique characteristic, two podal papillae in the thoracic neuropodia, might be a malformation, as this was only found in one parapodia on one side of one specimen. The specimens studied here are in agreement with the original description.
