title: A phylogenetic review of the North American band-winged grasshopper genus,EncoptolophusScudder with description ofNebulatettixgen.n. (Orthoptera: Acrididae: Oedipodinae).
abstract: A taxonomic review of the North American band-winged grasshopper genusEncoptolophusScudder (Orthoptera: Acrididae: Oedipodinae) was conducted. This genus is hypothesized to be non-monophyletic following a cladistic analysis of the genera in theChortophagagenus group. We examined all species currently classified in this genus group for morphological characters and one behavioral character. The phenotypic character data were combined with three mitochondrial genes: cytochromecoxidase subunit II, 16S rRNA and 12S rRNA. A parsimony analysis was performed on the combined data resulting in two equally parsimonious trees.Encoptolophus, as historically defined, is resolved in three separate clades. The results support erection of a new genus,NebulatettixGómez, Lightfoot & Miller gen.n. to comprise one of the groups historically classified inEncoptolophus. In addition, we transfer the speciesEncoptolophus californicusBruner toChimarocephalaScudder, comb.n., a combination used historically. The evolution of certain characters in theChortophagagroup is discussed, and a key to the genera is provided.
