Tetraliidae and Trapeziidae (Crustacea, Decapoda, Brachyura) from the Early Eocene of Monte Magrè (Vicenza, NE Italy)
The decapod crustaceans of the families Tetraliidae and Trapeziidae from the Early Eocene (middle-late Ypresian) of Monte Magrè (Schio, Vicenza, NE Italy), are described. The specimens are assigned to <em>Eurotetralia loerenthey</em> (Müller, 1975) n. gen., <em>Tetralia vicetina</em> n. sp. (Tetraliidae Castro, Ng & Ahyong, 2004); <em>Archaeotetra lessinea</em> n. sp., <em>Eomaldivia trispinosa</em> Müller & Collins, 1991, <em>Paratetralia convexa</em> Beschin, Busulini, De Angeli & Tessier, 2007, and <em>Paratetralia sulcata</em> n. sp. (Trapeziidae Miers, 1886).<br />The specimens were discovered associated with other decapods, in the coral-rich limestone. This report is the oldest fossil record of both two families. The stratigraphical distribution of the Tetraliidae and Trapeziidae is extended back to the middle-late Ypresian.
