An entomophthoralean fungus (Zygomycotina; Zygomycetes) from the ENTOMOPHAGA GRYLLI species complex has been found and described from Brazil, on populations of RHAMMATOCERUS BRASILIENSIS Bruner, 1904, RHAMMATOCERUS BRUNNERI Giglio Tos, 1895, ABRACRIS DILECTA Walker, 1870, ABRACRIS FLAVOLINEATA De Geer, 1773, and on an unidentified species of grasshopper from the subfamily Ommatolampinae (Acrididae). All of these grasshopper species were attacked by an ENTOMOPHAGA species presumably belonging to the E. GRYLLI species complex; it is impossible to say at this time whether the Brazilian fungus represents collections of a known (described) taxon or a new and undescribed member of this species complex. This new finding of E. GRYLLI is a scientific contribution to the knowledge of the Entomophthorales in Brazil and opens opportunities for further studies since this pathogen causes natural epizootics that, on many occasions, have had significant impacts by the reduction of acridid populations.
