Technical Abstract: Fungi from the Entomophthoraceae (Zygomycotina; Zygomycetes: Entomophthorales) belonging to the Entomophaga grylli species complex have been found in the state of Bahia, Brazil, to affect populations of grasshoppers (Orthoptera: Acrididae) of the species Rhammatocerus brasiliensis Bruner, Rhammatocerus brunneri Giglio Tos, Abracris dilecta Walker, Abracris flavolineata De Geer, and an unidentified species from the subfamily Ommatolampinae (Acrididae). It is impossible to say at this time whether the Brazilian collections represent a known (previously described) taxon or a new and undescribed member of this species complex. These new findings of the E. grylli complex expand the knowledge of the Entomophthorales in Brazil and open opportunites for further studies of these grasshopper pathogens that cause natural epizootics that, on many occasions, have significantly reduced populations of diverse acridids throughout the world.
