Abstract

A new species of the paromomyid genus Arcius was recently described from the early Eocene locality of Masia de l'Hereuet in northeastern Spain. Reassessment of the holotype of this species reveals that it belongs to the apatemyid genus Heterohyus. Heterohyus ilerdensis, comb. nov., is the earliest record of Apatemyidae from Spain and the oldest species of Heterohyus described to date. Heterohyus radiated in the middle and late Eocene of western Europe before succumbing to extinction around the time of the Grande Coupure. Arcius is documented at Masia de l'Hereuet, but the three specimens currently known from the site are inadequate to be confidently assigned at the species level.
