Nouvelles sous-espèces de Phillipsastrea hennahi (LONSDALE, W., 1840) dans le Frasnien supérieur de la Belgique

Phillipsastrea hennahi falsa n. subsp. is described from nodular limestones of late Frasnian age in the Philippeville and Visé Massifs. P. hennahi ranciae n. subsp. is described from two bioherms ("red marble" reefs) of the uppermost Frasnian at Rance. The two new subspecies are associated with Frechaslraea pemagona minima (ROZKOWSKA, M., 1953).
