Cycloseris vaughani ( Boschma, 1923)

( Fig. 3K )

Not Cycloseris vaughani – Turak & DeVantier, 2011: 129 (= Cycloseris costulata ).

This free-living species is rare at Brunei: recorded only at Colombo Reef, Champion Shoal ( Table 2). The lower order costae are larger and sharper than in its congeners. The species has a patchy greyish-brown colour, usually with a radiating pattern ( Fig. 2K ; Hoeksema, 1989; Hoeksema & Van Ofwegen, 2004). The specimens illustrated by Turak & DeVantier (2011) are wrongly identified.

Fig. 2. Species richness estimators (Colwell, 2009) for Fungiidae recorded at 17 sites off Brunei. The curves indicate that the occurrence of one additional species is possible when the maximum number of observed species (S Obs = 32) is compared to the maximum expected numbers (ICE, Chao 2 = 33). Only two species (Uniques) are each represented by a single individual.
