    Abstract
    Systematics, distribution, and host relations of the amblyopinine genus Edrabius (Coleoptera: Staphylinidae) are reviewed. Herein, we recognize 11 species in the genus Edrabius, all of which are obligate associates of South American caviomorph rodents of the families Caviidae, Ctenomyidae, and Octodontidae (Mammalia: Rodentia), and restricted to the southern cone of the continent. Three new species are described: Edrabius grandis (host: Ctenomys coyhaiquensis and C. haigi); Edrabius australis (host: Ctenomys maulinus maulinus); and Edrabius chilensiformis (host: Octodon degus). New distribution and host records are given for E. alticolus Seevers, E. argentinus Seevers, E. chilensis Scheerpeltz, E. peruanus Seevers, E. philippianus Fauvel, and E. weiseri Seevers. Occurrence of Edrabius on octodontid rodents is reported for the first time (E. chilensis from Aconaemys and E. chilensiformis from Octodon). The genus Edrabius was formerly known to occur in association with various species of Ctenomys, with the exception of one species, E. kuscheli, associated with Galea musteloides (Caviidae).
     
    RESUMEN—Se presenta una revisión de la sistemática, la distribución y las relaciones de los hospederos de los amblyopininos del género Edrabius (Coleoptera: Staphylinidae). Se reconocen 11 especies de Edrabius, todas parásitos obligados de roedores caviomorfos sudamericanos de las familias Caviidae, Ctenomyidae y Octodontidae (Mammalia: Rodentia). Se describen tres nuevas especies: Edrabius grandis, hospedador: Ctenomys haigi); Edrabius australis, hospedador: Ctenomys maulinus maulinus); y Edrabius chilensiformis, hospedador: Ocrodon degus). Se entregan nuevos registros distribucionales y de hospederos para E. alticolus Seevers, E. argentinus Seevers, E. chilensis Scheerpeltz, E. peruanus Seevers, E. philippianus Fauvel y E. weiseri Seevers. Por primera vez se reporta la presencia de Edrabius en roedores octodóntidos (E. chilensis en Aconaemys y E. chilensiformis en Octodon). EI género Edrabius anterionnente se conocía solamente asociado a diferentes especies de Ctenomys, con la excepción de una especie, E. kuscheli, asociada a Galea musteloides (Caviidae).
