Odontosyllis

Aguado, M. Teresa, Murray, Anna & Hutchings, Pat, 2015, Syllidae (Annelida: Phyllodocida) from Lizard Island, Great Barrier Reef, Australia, Zootaxa 4019 (1), pp. 35-60 : 41-42

Odontosyllis sp. 1

( Figs 1 C, E, 3F–N)

Material examined. AM W.47187, MI QLD 2380 (1 on 2 SEM pins).

Remarks. This specimen has anterior chaetigers with bidentate chaetae, with a minute distal tooth, similar to those of O. robustus n. sp. ( Figs 3 F–I). However, middle and posterior chaetigers also show unidentate chaetae, similar in shape to those of O. globulocirrata Hartmann-Schröder, 1981 ( Figs 3 J–N). It has a similar colour pattern to O. robustus n. sp. but with orange spots on alternating parapodia, at the base of dorsal cirri ( Figs 1 C, E). First report from Queensland.

Habitat. Halimeda algae, in shallow waters.

Distribution. Australia (Queensland).
