Classification
Remarks
Originally, the genus Koilomorpha Alloiteau, 1952, was placed in the Thamnasteriidae. Later, Wells (1956, p. 381) provisionally grouped it as a junior synonym with Microphyllia, the latter of which many authors have placed in the Latomeandridae. However, because the type material of the type species is characterized by e.g., perforated septa, that are strongly beaded and dentated, as well as numerous synapticulae that form synapticulothecal walls, the genus Koilomorpha rather belongs to the Siderastreidae and closely corresponds to the genus Pironastraea d'Achiardi (Baron-Szabo, 2008, p. 12 and 142).
