Mitochondrial DNA variation in the South American grasshopper Dichroplus elongatus (Orthoptera: Acrididae)
Dichroplus clongatus (Giglio-Tos)is a phytophagous grasshopper widely distributed in Argentina. In the current work, the genetic variation and phylogeogrphy of this species was studied with mtDNA techniques. In total, 171 individuals from northwestern (Las Yungas province) and eastern (Espinal and P...

Dichroplus clongatus (Giglio-Tos)is a phytophagous grasshopper widely distributed in Argentina. In the current work, the genetic variation and phylogeogrphy of this species was studied with mtDNA techniques. In total, 171 individuals from northwestern (Las Yungas province) and eastern (Espinal and Pampeana provinces) Argentina populations were analyzed using restriction fragment-length, polymorphism. The number of substitutions per site between pairs of haplotypes ranged from 0.65 to 3.84%. The neighbor-joining phenogram yielded two main groups: one clusters together the haplotypes restricted to the east and the other the haplotypes restricted to the northwestern region. Phylogenetic consensus unrooted tree among mtDNA haplotypes allowed us to propose the ancestral haplotype, which occupies the central position of the network.
