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 ). 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 ). Thoracic postchaetal neuropodial lobes as ridges with up to 9 papillae, upper papillae larger than lower ( Fig. 24B, D, E, G ). 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 ). 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 ). Notopodial chaetae crenulate capillaries, in abdominal notopodia also forked chaetae present ( Fig. 24J ). 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 , G–I).
