Cycloseris fragilis ( Alcock, 1893)

( Fig. 3A, B )

Cycloseris patelliformis – Turak & DeVantier, 2011: 128. Diaseris distorta (partim) – Turak & DeVantier, 2011: 130.

Not Diaseris fragilis – Turak & DeVantier, 2011: 131 (= C. sinensis ).

This free-living species is moderately common at Brunei: recorded at 7 out of 17 sites ( Table 2). It was observed in complete and in fragmenting shape. It has also been recorded as C. patelliformis ( Boschma, 1923) (see Turak & DeVantier, 2011), which actually is a synonym of C. fragilis (see Hoeksema, 1989). Live specimens photographed in Indonesia and identified as D. distorta by Turak & DeVantier (2011) show thin septa, which are typical for C. fragilis and not for C. distorta (compare Hoeksema, 1989). Diaseris is considered a synonym of Cycloseris (Hoeksema, 1989; Hoeksema & Waheed, 2011, 2012).
