Remark Based on re-investigation of the type material Alloiteau (1957) postulated a generic concept for Ovalastrea different from the one which had been previously introduced by Vaughan and Wells (1943), and Wells (1956). The main differences between the two concepts are in the septal and thecal development (according to Alloiteau septa are compact and not perforated, and the wall is septothecal and parathecal, but not synapticulothecal). Re-study of the holotype of the type species of Ovalastrea (Astrea caryophylloides Goldfuss; IPB no. 221, Goldfuss collection) in 2005 (see discussion in Baron-Szabo, 2014) revealed the following characteristics for Ovalastrea: Colonial, massive, plocoid, sub-cerioid, sub-meandroid. Gemmation generally intracalicinal, forming short series; extracalicinal budding present in a few places; costosepta compact, nonconfluent, dentate distally, granulated laterally; a small number of paliform structures irregularly present; columella spongy-papillose or lamellar; wall parathecal to septoparathecal, a small number of synapticulae seem to be present; endothecal and exothecal dissepiments very thin, abundant. Because the genus Plesiofavia Alloiteau, 1957, closely corresponds to Ovalastrea, they are considered synonymous. For a different view on the taxonomic position of Ovalastrea, see discussion at Ovalastrea on corallosphere. [details]
