Type locality. South Island , New Zealand .

Description. Large worms, with thoracic width up to 3.8 mm, length more than 50 mm, more than 200 segments ( Fig. 1A View FIGURE 1 ). Body cylindrical, thorax often swollen in anterior part, segments short ( Fig. 1A, C View FIGURE 1 ). Prostomium sharply conical ( Fig. 1B, C, E View FIGURE 1 ). Thoracic chaetigers numbering 16–18 (12 in one smaller specimen). Branchiae from chaetiger 16–20 (last thoracic or first or second abdominal segment) as small triangle papillae, gradually increasing in size and becoming narrow triangular, shorter than notopodial lobes; in middle and posterior abdomen branchiae dichotomously branched with 3–4 branches ( Fig. 1B, C, F, J View FIGURE 1 ). In smaller worms branched branchia present only close to pygidium, with two short branches. Thoracic postchaetal lobes developed from first chaetiger, both triangular, notopodial longer than neuropodial ( Fig. 1 View FIGURE 1 B–E, G). No subpodal or stomach papillae. Abdominal notopodial postchaetal lobes foliaceous; neuropodial lobes uniramous, triangular ( Fig. 1F, J View FIGURE 1 ). Pygidium with fimbriated margin and two short anal cirri ( Fig. 1I View FIGURE 1 ). Chaetae crenulated capillaries in all parapodia; straight weakly serrated uncini also present in thoracic neuropodia, forming anterior row curving under numerous capillary chaetae and continuing dorsally as short posterior row ( Fig. 1C, E, G View FIGURE 1 ). One projecting acicular chaeta in abdominal neuropodia; forked chaetae not seen ( Fig. 1J View FIGURE 1 ).

Distribution. Australia, Western Australia, South Australia, Victoria, Tasmania, New South Wales, New Zealand.

Habitat. Intertidal and upper subtidal, seagrass, algae, polychaete tubes, mixed sediments.

Remarks. For the detailed history of the species see Blake (2017, pp. 51–52). In addition, Blake (2017) moved Scoloplos cylindrifer to the genus Leodamas , group B. The specimens examined in the present study are in agreement with the descriptions by Hartman (1957), Day (1975), and Hartmann-Schröder (1981).
