Description. Large worms, thoracic width 1.6–5.7 mm. Body long, thorax flattened, abdomen cylindrical (Fig. 15A). Prostomium short and wide, rectangular (Fig. 15B). Thoracic chaetigers numbering 30–38 (Fig. 15A). Branchiae from chaetiger 6, narrow triangular, in abdomen becoming long with tapering tips, longer than notopodia (Fig. 15B, E). Thoracic notopodial postchaetal lobes from first chaetiger, digitate to triangular; in abdomen becoming long narrow foliaceous with tapering tips (Fig. 15B, D, E). Thoracic neuropodial postchaetal lobes as ridges with one papilla, situated in middle part of ridge on anterior chaetigers; from chaetiger 7 lobe shifting to uppermost part of ridge (Fig. 15 A–C). Abdominal neuropodia simple narrow triangular; subpodal flange not developed (Fig. 15E). No subpodal, stomach, or flange papillae; no interramal cirrus. Notopodial chaetae crenulate capillaries, in abdominal notopodia also forked chaetae present; thoracic neuropodia bearing subuluncini with thick base and sharply tapering tips and thin curved serrated uncini in superior position, and 2–3 rows of capillaries; abdominal neuropodia with capillaries only (Fig. 15 C–E). Both rami supported by two straight aciculae in abdomen (Fig. 15E). Distribution . Australia, Queensland, New South Wales, Victoria, South Australia, Western Australia. Habitat. Intertidal and upper subtidal, sandy mud, mud, seagrass. Remarks. Naineris grubei australis was described from Adelaide, South Australia, and later found in Victoria, New South Wales, and Western Australia (Hutchings & Rainer 1979; Hutchings & Murray 1984; Hartmann- Schröder 1980). Recently, the species was redescribed and illustrated based on specimens from Lizard Island, Queensland (Zhadan et al ., 2015). Blake (2017) re-examined specimens of N. grubei and raised N. grubei australis to a full species because of the difference in neurochaetal structure. The distribution of N. grubei is restricted to Ecuador, Peru, and Chile, whereas N. australis is restricted to Australian waters. : Published as part of Zhadan, Anna, 2020, Review of Orbiniidae (Annelida, Sedentaria) from Australia, pp. 451-502 in Zootaxa 4860 (4) on pages 479-480, DOI: 10.11646/zootaxa.4860.4.1, http://zenodo.org/record/4414137 : {"references": ["Day, J.
