Morphologically similar species. Syllis gracilis and Sylis ypsiloides (see material examined above)

Description. Longest examined specimen incomplete, 23 mm long, 0.25 mm wide, with 53 chaetigers. Body slender, anterior segments pigmented, each with one reddish-orange, transversal line ( Fig. 9 View FIGURE 9 C). Prostomium oval, wider than long, with two pairs of red eyes in trapezoidal arrangement ( Figs 9 View FIGURE 9 C, 10F, 11A). Median antenna inserted on middle of prostomium, between anterior pair of eyes, with 12–13 articles ( Figs 9 View FIGURE 9 C, 10F, 11A); lateral antennae shorter, inserted at anterior margin of prostomium, with 8–9 articles ( Figs 9 View FIGURE 9 C, 10F, 11A). Palps triangular, longer than prostomium. Nuchal organs not seen. Peristomium slightly shorter than subsequent segments. Dorsal tentacular cirri similar in length to median antenna, with 13–14 articles, ventral ones shorter with 10–11 articles ( Figs 9 View FIGURE 9 C, 10F, 11A). Anterior dorsal cirri with 12–14 articles ( Figs 9 View FIGURE 9 C, 10F, 11A); midbody and posterior dorsal cirri spindle-shaped, shorter than anterior ones, with 9–11 articles ( Figs 9 View FIGURE 9 D–E, F3, 11B). Anterior parapodia with 8–10 bidentate, falciger chaetae. Bidentate blades with both teeth similar in length, and several spines on margin ( Figs 10 View FIGURE 10 G, 11C). Each midbody and posterior parapodia with three chaetae, with shorter blades and enlarged shafts: 1–2 ypsiloid chaetae, originated from fusion of blade and shaft, fusion line distinguishable ( Figs 9 View FIGURE 9 F4, 10H–I); and 1–2 falcigers slightly bidentate ( Fig. 10 View FIGURE 10 I, 11D). Some posteriormost parapodia presenting dorsal and ventral simple chaetae, slightly bidentate, with spines on margin ( Fig. 11 View FIGURE 11 E–F). Three to four straight aciculae in each anterior parapodia ( Fig. 11 View FIGURE 11 G); midbody parapodia with two aciculae each, one distally pointed and other distally blunt ( Fig. 11 View FIGURE 11 H); posterior parapodia with only one distally blunt acicula each ( Fig. 11 View FIGURE 11 I). Pharynx much longer than proventricle, extending through 17–18 segments ( Figs 9 View FIGURE 9 C, 11A); conical tooth located on anterior margin. Proventricle through 5 segments with about 32 muscle cell rows ( Figs 9 View FIGURE 9 C, 11A).

Remarks. Morphological differences between S. picta n. comb. and S. gracilis have been described above. The main differences with S. ypsilodes are the number per parapodium and shape of midbody chaetae, since S. ypsilodes presents only two chaetae, one unidentate falciger and one ypsiloid chaetae, whereas S. picta n. comb. presents three chaetae, one or two falcigers sometimes slightly bidentate and one ypsiloid chaeta (compare Fig. 10 View FIGURE 10 – I and Aguado et al. 2008 for comparisons). Syllis picta Grube, 1870 (non Syllis picta Kinberg, 1865 ) was considered by Licher (1999) as synonimous of Typosyllis violacea ( Grube, 1870) , so it is not an homonym of Syllis picta n. comb.

Habitat. Coral rubble, algae.

Distribution. Australia (New South Wales, Western Australia, Northern Territory).
