Abstract
Abstract The grasshopper subfamily Melanoplinae, comprising a large number of genera and species, maintains a distribution throughout Eurasia and the New World. Despite various attempts to subdivide the subfamily, taxonomic assignments within the Melanoplinae remain unclear. However, the placement of Eurasian and related Nearctic genera within a separate tribe, Podismini, is a common feature within most proposed taxonomic schemes. The Podismini have been independently divided into two and four subtribes on the basis of cytogenetic and morphological traits, respectively; however, the two schemes differ with respect to the placement of certain genera. This study analyses sequence data obtained from portions of four mitochondrial genes (cyt b, COII, ND2, and COI) to (1) test the hypothesis that Eurasian podismines are monophyletic and (2) examine which, if any, of the proposed subtribal affiliations is correct. The view that the nominate genus, Podisma, represents a form closely related to the ancestral podi...
