<p class="abstract-testo">The middle Cretaceous genus <em>Paronastraea</em> Beauvais, 1977 is being revised on the basis of sample material available from Italy, France, Germany, and Greece. <em>Paronastraea</em>, a plocoid and cerioid coral similar to <em>Pachycoenia</em>, is characterised by regular secondary septal apophyses arranged in pairs. Six species are distinguished by their respective numbers of septal cycles and systems, two of them in open nomenclature and one, <em>Paronastraea</em> <em>occulta</em> from the Early Aptian of Greece, is newly described. The genus occurred from the Barremian to the basal Cenomanian in the central and eastern Tethys.</p><p class="abstract-testo"></p>
