Holotype SMNH-Type-527 (in two fragments, few posterior segments missing), “Eugenie“ Exp. 1851–53, St. 1879–81, Magellan Strait, 53°S 72°W. Additional material. 1 spm. (af), SMF 20030, San José Gulf (Argentina), Isla de los Pájeros, 18 January 1975, shallow subtidal. 1 spm. (out of 3, cf. Hartmann-Schröder 1989, cs), ZMH V- 4696, Magellan Strait, Punta Arenas. Diagnosis. Prostomium with distinct cephalic peaks. Antennae and cirri not very long. Elytra, large, overlapping, covering dorsum. Tip of neuropodial acicular lobe extended to thick, stout supra-acicular process. Neurochaetae all bidentate. Ventral cirri short, not reaching to tip of neuropodia. Description (based on additional spm. SMF 20030 without elytra, completed by spm. ZMH V-4696 for elytra and missing prostomial appendages). Prostomium bilobed, with distinct cephalic peaks (Fig. 4 A); ceratophore of median antenna in anterior notch, style smooth, tapering, longer than palps; lateral antennae inserted ventrally to median antenna, styles smooth, tapering; anterior pair of eyes situated dorsolaterally slightly in front of widest part of prostomium, posterior pair dorsally near hind margin of prostomium; palps tapering. First or tentacular segment with a pair of tentaculophores inserted laterally to prostomium, without notochaetae, but with a dorsal and a ventral tentacular cirrus, styles smooth, tapering (Fig. 4 A). Second or buccal segment with first pair of elytra, biramous parapodia and long tapering ventral or buccal cirri. Following segments with ventral cirri short, not reaching to tip of neuropodium (Fig. 4 C). 15 pairs of ...
