Aricia laevgata Grube, 1855: 112–113 , plate IV, fig. 6–8.

Naineris laevigata: Hartman, 1957: 297–298 , plate 35, figs. 1–8; Day 1967: 539–540, fig. 23.2 a–f; Day 1977: 237.

Material examined. Western Australia: Cottesloe Beach, 9.5 km west of Perth, 31°59’S, 115°45’E, 14.02.1970, depth 0.5 m, coll. H. Paxton, in calcaerous algae and Idanthyrsus ( Sabellariidae ) tubes, AM W.4365, 4 specimens.

Type locality. Mediterranean Sea.

Description. Body moderately long, cylindrical, thorax swollen in anterior part, slightly flattened in posterior; thoracic width 0.7–2.8 mm ( Fig. 16A, B View FIGURE 16 ). Prostomium round or conical-round, flattened dorso-ventrally ( Fig. 16B, C View FIGURE 16 ). Thoracic chaetigers numbering 11–18 ( Fig. 16B View FIGURE 16 ). Branchiae from chaetiger 5–8, small triangular in thoracic chaetigers; in abdomen rapidly increasing in size, becoming long and wide, triangular with tapering tips, longer than notopodia ( Fig. 16C, E, F, H View FIGURE 16 ). Thoracic notopodial postchaetal lobes developed from first chaetiger, wide foliaceous; in abdomen of same size and shape ( Fig. 16 View FIGURE 16 B–F, H). Thoracic neuropodial postchaetal lobes triangular with wide bases and tips forming round papillae in upper part; in abdomen becoming smaller, triangular ( Fig. 16B View FIGURE 16 , D–H). No subpodal, stomach or flange papillae, subpodal flange, interramal cirrus. Pygidium with papillate margin and four short cirri ( Fig. 16E View FIGURE 16 ). Notopodial chaetae crenulate capillaries, in abdominal notopodia forked chaetae present ( Fig. 16F, H, I View FIGURE 16 ). Thoracic neuropodia bearing three kinds of chaetae: crenulate capillaries, uncini, which can be thick smooth or thin curved and serrated, and thick curved subuluncini with long pointed tips ( Fig. 16F, G View FIGURE 16 ). Abdominal neuropodia bearing thin capillaries and 3–4 projecting slightly curved aciculae ( Fig. 16H View FIGURE 16 ).

Distribution. Tropical waters in Atlantic, Pacific and Indian oceans; Australia, Western Australia, New South Wales, Victoria, New Zealand.

Habitat. Intertidal, muddy sand, algae, sabellariid tubes.

Remarks. Naineris laevigata was described from the Mediterranean Sea. This species has a large morphological variability and wide distribution in tropical waters (Hartman 1957). Whether all populations belong to one species needs to be confirmed by thorough investigations of material from different localities. The specimens stud- ied here are in agreement with previous descriptions: Hartman (1957) based on material from Florida, Galapagos Islands, Hawaiian Islands and Peru; Day (1967) on material from South Africa.
