Redefinition of the genus Parabyrsopolis Ohaus and description of a new species from west-central Mexico (Coleoptera: Scarabaeidae: Rutelinae: Rutelini).

The morphological limits of the genus Parabyrsopolis Ohaus (Coleoptera: Scarabaeidae: Rutelinae: Rutelini: Areodina) are redefined and Parabyrsopolis moroni new species is described from west-central Mexico. With this addition, the genus now includes five species that are distributed from southwestern United States of America to central Mexico. Diagnostic morphological characters and comparison with other Parabyrsopolis species are included, and some considerations about the morphological limits between Parabyrsopolis and Viridimicus Jameson are discussed.
