Characters: Polyps are approximately circular, nearly flat to strongly convex, with a flat or concave undersurface. The central arch is well formed. Septa are irregular, with ragged margins.
Colour: Brown or mottled.
Similar Species: Cycloseris curvata, which has characteristically curved septa and usually lacks a central arch.
Habitat: Soft inter-reef substrates.
Abundance: Rare.
Taxonomic Note: Considered a junior synonym of Cycloseris tenuis by Hoeksema (1989a). However, it is retained here because of characteristic differences in septal configuration.
