Glycera sagittariae McIntosh, 1885: 346; pl. 42, fig. 8; pl. 22A, fig. 10.
Material examined. AM W.45468, MI QLD 2444 (2), cs/9/88/0.9/0.5, cs/7/66/0.9/0.5; AM W.47221, MI QLD 2444, af/13/92/2.5/1.5, part of proboscis on SEM stub; AM W.46214, Lizard Island, 100 m off eastern end of Mangrove Beach, undulating sand, filamentous algae, 3 m, 11 Oct 1978, cs/52/192/2.0/1.4, part of proboscis on SEM stub.
Diagnosis. Proboscidial papillae mainly conical with 3 ridges; ailerons with triangular bases; parapodia of mid-body with rounded, sometimes slightly blunt triangular postchaetal lobes, notopodial lobes usually slightly broader and longer than neuropodial lobes; simple, retractile, digitiform branchiae, situated medially on anterior side of parapodia.
Description. Body up to 52 mm long with up to 192 chaetigers. Mid-body segments bi-annulate.
Conical prostomium consisting of about 11–12 rings; terminal ring with four appendages and basal one with pair of nuchal organs (Fig. 5 A).
Proboscis with two types of papillae: l. numerous conical papillae with 3 U-shaped ridges, sometimes with additional subterminal straight, median, longitudinal ridge; 2. isolated, broader, oval to globular papillae without ridges (Figs 5 B, 10D). Terminal part of proboscis with four hook-shaped jaws arranged in a cross and accessory ailerons with triangular base (Fig. 5 A, C).
First two pairs of parapodia uniramous; following parapodia biramous (Fig. 5 D–K). Two slender triangular to digitiform prechaetal lobes of about same length; both lobes becoming slightly thinner in posterior parapodia; in last parapodia notopodial lobe shorter than neuropodial one. Two shorter postchaetal lobes; anteriorly both lobes rounded; in following parapodia both lobes slightly elongated and rounded, sometimes slightly blunt triangular; notopodial lobe usually slightly longer than neuropodial lobe; in posteriormost parapodia both lobes generally shorter and rounded. Dorsal cirri from 3rd parapodium, conical to oval; inserted on body wall slightly above parapodial base. Ventral cirri slender triangular to digitiform, about as long as postchaetal lobes; in posterior parapodia slender and elongated; in last parapodia about as long as neuropodial prechaetal lobe; situated medioventrally on parapodia. Branchiae retractile, simple, digitiform (Fig. 5 F); starting in anterior region to near posterior end; situated medially on anterior side of parapodia.
Noto- and neuropodia each with a single acicula (Fig. 5 D–K). Notochaetae capillaries. Neurochaetae compound spinigers with blades of different lengths.
Pygidium with dorsal anus and terminal pair of slender, elongated cirri.
Distribution. Lizard Island; 3– 24 m.
