A new actinopterygian, Moradebrichthys vilasecae gen. et sp. nov., from the Middle Triassic (Late Ladinian) of Móra d'Ebre-Camposines (Catalonia, NE Iberian Peninsula) is erected on the basis of several, almost complete, articulated and well-preserved specimens. It is referred to the controversial family Perleididae based on the presence of a combination of features such as paried nasals, presence of rostral, vertical suspensorium, absence of interopercle, lack of coronoid in the mandible, basal and fringing fulcra on fins developed to different extents and an almost symmetrical caudal fin with epaxial fin rays. Comparisons to other well-known taxa usually assigned to the Perleididae family reveals that the new taxon presents many similarities with the genera Perleidus, Peltoperleidus, Aetheodontus and Meridensia, rather than other perleidids. Moreover, additional morphological characters, not shared with any of these genera are: a big half moon shaped infraorbital-2 and one elongate infraorbital-1, a narrow vertical preopercle with a prominent and pointed anterior maxillary process, a dentary covered by horizontally arranged ridges, a very big opercle and a much smaller subopercle, and the high level of lepidotrichia branching in the caudal fin. A comparison of Catalan Middle Triassic actinopterygian assemblages with other ones from Central European basins of coeval age (particularly Italian and Swiss localities) suggest some faunal similarities, being of special interest the potential correlation with the Besano Formation.
