Thoracic chaetigers numbering 15 ( Fig. 24A, C, D, E View FIGURE 24 ). Branchiae from chaetiger 5, wide triangular, foliaceous, in abdomen becoming long triangular with widened base and tapering tips, longer than notopodia ( Fig. 24C, E, J, K View FIGURE 24 ). Thoracic notopodial postchaetal lobes developed from first chaetiger, from digitiform to foliaceous, in abdomen becoming elongate, in anterior part, foliaceous with wide base, in posterior narrow digitate ( Fig. 24A, C, E, I, J View FIGURE 24 ). Thoracic postchaetal neuropodial lobes as ridges with up to 9 papillae, upper papillae larger than lower ( Fig. 24B, D, E, G View FIGURE 24 ). Subpodal papillae present on last thoracic and first two abdominal chaetigers, few stomach papillae only in first two abdominal chaetigers ( Fig. 24A, B, D, E View FIGURE 24 ). Abdominal neuropodia bilobed with subequal short lobes; subpodal flange developed, with papilla (ventral cirrus). Interramal cirrus small, shorter than neuropodia ( Fig. 24B, E, F, J View FIGURE 24 ). Notopodial chaetae crenulate capillaries, in abdominal notopodia also forked chaetae present ( Fig. 24J View FIGURE 24 ). Thoracic neuropodia bearing 2–3 rows of thin curved serrated uncini and posterior row of capillaries; posterior thoracic chaetigers bearing very thick brown straight spines, upper one longer than others ( Fig. 24B, D, E View FIGURE 24 , G–I). Abdominal neurochaetae thin capillaries; both rami supported by thin straight aciculae in abdomen. Distribution. New Zealand. Habitat. Subtidal. Remarks.
