The genus Pedies was described by Saussure in 1861 for the Mexican species Pedies virescens. In 1917 Hebard synoymized Paradichroplus Brunner von Wattenwyl under Pedies, and assigned Platyphyma mexicanus Bruner, Melanoplus variabilis Scudder, and Paradichroplus andeanus Bruner to Pedies (with its type species, P. virescens Saussure). Later, Hebard (1931) considered Pedies mexicanus (Bruner) to be a junior synonym of Pedies virescens. More recently, Ronderos and Carbonell (1994) decided that the only described species of Pedies from South America, Pedies andeanus (Bruner), should be placed into the South American tribe Dichroplini because it shared the synapomorphy of the group (a pair of internal lobes in the pallium of the male genitalia). Thus, they (Ronderos and Carbonell, 1994) removed P. andeanus from Pedies and erected the new Dichroplini genus Orotettix for it. Based on the examination of material deposited in the Academy of Natural Sciences of Philadelphia we re-define the genus Pedies and describe nine new species, and we remove P. variabilis from Pedies and include it into the new genus Akamasacris, together with four new species.Pedies was described by Saussure in 1861 for the Mexican species Pedies virescens.
