New South Wales: North Head, Port Jackson, 33°49’ 30”S, 151°18’E, 25.05.1972, Australian Museum Shelf Benthic Survey , depth 30 m, Holotype, AM W.199516; east of Malabar , 33°58’34”S, 151°16’52”E, 17.04.1989, coll. Fisheries Research Institute ( NSW), sand, depth 60 m, AM W.20694; 2 specimens. GoogleMaps

Type locality. Port Jackson, North Head , New South Wales .

Description. Holotype with thoracic width 1.6 mm, two other specimens 0.9 mm and 1.2 mm, body length about 23 mm, about 140 chaetigers ( Fig. 9A, D View FIGURE 9 ). Prostomium sharply conical ( Fig. 9D View FIGURE 9 ). Thorax flattened, abdomen cylindrical; 13–15 thoracic chaetigers ( Fig. 9A, B, D View FIGURE 9 ). Branchiae from chaetigers 12–13 as small triangle papillae, then gradually increasing in size, in abdomen branchiae becoming digitate and triangular with round tips, shorter than notopodial lobes ( Fig. 9D, E, H View FIGURE 9 ). Thoracic postchaetal lobes small papilliform on anterior segments, then gradually increasing in size, becoming triangular; notopodial lobes longer than on neuropodia; no subpodal or stomach papillae ( Fig. 9B, C, G View FIGURE 9 ). Abdominal notopodial lobes narrow, foliaceous ( Fig. 9E, H, I View FIGURE 9 ). Abdominal neuropodial postchaetal lobes bilobate, with both lobes well developed; inner lobe longer and wider than outer ( Fig. 9C, E, H, I View FIGURE 9 ). No subpodal notch and flange. Pygidium with two anal cirri ( Fig. 9F View FIGURE 9 ). All parapodia bearing crenulate capillaries, abdominal notopodia with forked chaetae ( Fig. 9G, H, I View FIGURE 9 ).

Distribution. Australia, New South Wales.

Habitat. Subtidal, sand, sandy mud.

Remarks. The specimens described in the present study correspond with the description by Mackie (1987). Leitoscoloplos bilobatus differs from the other species of the genus by the absence of a subpodal notch and subpodal flange in the abdominal neuropodia.
