Morphometric variation affecting sexual size dimorphism in Neopedies brunneri (Orthoptera: Acrididae)

Neopedies brunneri (Giglio-Tos, 1894) is a grasshopper belonging to the family Acrididae. This group of insects usually has economic importance in Argentina because of their ability to experience outbreaks, but little is known about them. Insect populations usually differ at the phenotypic level, of...
