Trypanosyllis (Trypanobia) depressa .— Imajima 1966b: 242, figs 46 a–f; 2003: 160; San Martín et al. 2008b: 43 –45, fig. 5.

Material examined. AM W.41259 (3, 1 on SEM stub), Lizard Island, High Rock, 14°49'27"S, 145°33'10"E, red sponge, 10 m, 11 Sep 2010, CReefs; AM W.41535, same.

GenBank COI accession number: KR364801 .

Remarks. The colour pattern could not be checked since fresh material was not collected during the 2013 Lizard Island Polychaete Workshop, and preserved specimens collected in 2010 had lost pigmentation ( Figs 9 C– D). Dorsum with series of small longitudinal crests on each segment ( Fig. 10 A), without papillae and cilia. Simple chaetae as described by Imajima (1966) and San Martín et al. (2008b) ( Figs 9 A–B, 10B–E). First report for Queensland.

Habitat. On red sponges, in subtidal depths.

Distribution. Australia (Western Australia, Queensland), Japan.
