Syllis boggemanni n. sp. Figures 2, 3 Material examined. AUSTRALIA, WESTERN AUSTRALIA: Kimberleys, Shirley Island, 16° 17' S, 123° 26' E, holotype, AM W.48526, coll. 26 July 1988, by Pat Hutchings. Description. Holotype incomplete, lacking most posterior segments, 11 mm long, 0.75 mm wide, with 58 chaetigers. Body large, robust, without colour pattern. Prostomium oval; 4 eyes in open trapezoidal arrangement and 2 minute anterior eyespots, difficult to see. Palps somewhat ventrally folded, similar in length to prostomium (Fig. 2 A). Median antenna arising slightly in front of posterior pair of eyes, with about 30 articles, distinctly longer than combined length of prostomium and palps; lateral antennae much shorter than median one, with 20–22 articles. Peristomium slightly shorter than subsequent segments (Fig. 2 A). Dorsal tentacular cirri similar in length to median antenna, with about 24 articles; ventral tentacular cirri about half as long as dorsal ones, with 20 smaller articles. Dorsal parapodial cirri elongated, whip-shaped, alternating in midbody long cirri, slightly longer than body width, with about 42–50 articles, and short cirri, somewhat shorter than body width, with about 30 articles (Fig. 2 A, B); cirrophores well developed, dorsal cirri dark, articles filled up with spiralized inclusions. Parapodia conical, distally bilobed. Ventral parapodial cirri digitiform. Compound chaetae including spiniger-like and falcigers on each parapodium (Fig. 3 A–F); blades and shafts slender on anterior segments becoming longer gradually from midbody to posterior parapodia (Fig. 3 A–F). Spiniger-like chaetae with bidentate blades, both teeth similar and close to each other, short spines on margin, except for distalmost 1–2 spines, which reach level of proximal tooth (Fig. 3 A, C, E). Falcigers with moderate to long spines on margin, especially 2–3 distalmost ones, reaching and even surpassing level of proximal tooth; bidentate, with proximal tooth slightly longer than distal one from midbody parapodia (Fig. 3 B, D, ...
