Material examined. AM W.44780, MI QLD 2400.

Remarks. Live specimen bright yellow, similar colour pattern to M. inflata (Marenzeller, 1879) ( Fig. 5 View FIGURE 5. A D). Some photographs taken by Paul Human of live specimens from Australia have been identified as M. corruscans (Haswell, 1885) and M. inflata by Aguado & Glasby (2015). These species and also M. heterosetosa , as shown herein ( Fig. 5 View FIGURE 5. A D), have a white area on the dorsum of first segments. In these photos, this white area appears to reflect green light. In order to check possible fluorescence properties of Megasyllis species, this specimen from Lizard Island was subjected to fluorescent green light. However, it did not reflect any extra light ( Fig. 5 View FIGURE 5. A E). Considering this negative result, we can conclude that the green bright light seen in photos of live specimens is possibly due to an optical artefact. First report for Lizard Island.

Habitat. Coralline and muddy sand and sea grasses, in intertidal to subtidal depths.

Distribution. Australia (Queensland, New South Wales), Japan.
