Abstract
Two new genera and seven new species, collected in the state of Oaxaca in Mexico, are described. The genera Reyesacris (R. amedegnatoae) and Oaxaca (O. colorata and O. carinata) are new to science. Melanoplus mixes, M. oaxacae and M. ludivinqe are newspecies for the genus Melanoplus Stal, 1873 and Cephalotettix chinantecus is new species for the genus Cephaloiettix Scudder, 1897. During past years collecting in Mexico within the framework of projects of CONABIO (Project GE 001), University of Padova(year 2004-2008) and WBA—World Biodiversity Association (2008-2009), new materials of Acrididae have been collected and partly described (Fontana & Buzzetti 2007, Buzzetti, Barrientos-Lozano & Fon-tana 2010). Here we describe more new taxa from the materials collected in Southern Mexico, Oaxaca State.
