As part of Portugal’s bid for extending the country’s exclusive economic zone, the EMEPC collection program was
initiated. From this program several new species of Tanaidacea have been collected during various expeditions. In this
paper three new species of Tanaidacea are described from the Azores archipelago in the Mid-Atlantic, Portugal. Two of
them belong to the apseudomorphan genera Leviapseudes (L. macaronesia), Pseudosphyrapus (P. azorensis), and another
new species belong to the tanaidomorphan genus Paratanais (P. pseudomartinsi).
