Cycloseris tenuis ( Dana, 1846)

( Fig. 3J )

Not Cycloseris tenuis – Turak & DeVantier, 2011: 129 (= Pleuractis granulosa , Cycloseris spp. ).

This free-living species is moderately common at Brunei: recorded at 9 out of 17 sites ( Table 2). The lower order costae are large and roughly ornamented. The species has a typical greyish-brown colour with dark brown around its mouth and white lips ( Gittenberger & Hoeksema, 2006). The specimens from Indonesia illustrated by Turak & DeVantier (2011) are wrongly identified.
