Phylogenetic studies in the South American tribe Dichroplini (Orthoptera: Acrididae: Melanoplinae): is the Paranaense-Pampeano informal genus group a natural clade?

The Dichroplini genera Scotussa, Leiotettix, Ronderosia, Atrachelacris, Chlorus, Eurotettix and Dichromatos have been grouped into the "Paranaense-Pampeano" informal genus group, based on characters of the male genitalia. However, recent molecular phylogenetic analyses showed weak support...
