Neorhagio Lindner was known to date exclusively from its type species, from Chile. The status of the genus among the Rhagionidae is controversial, sometimes confounded with Atherimorpha White or Rhagio Fabricius. Two new species of Neorhagio, N. caligatus sp. n. and N. nagatomii sp. n., are described and illustrated based on material collected in the Reserva ‘Biosfera’ El Triunfo, Northern Mexico. The differences between Neorhagio, Atherimorpha and Rhagio are considered, and comments are made on the presence of posteroventral cercal lobes in Rhagionidae.
