Etymology. the species is dedicated to Christiane Amedegnato (sadly passed away in June 2010), Researcher at CNRS and responsible for the Caelifera collection at the Muséum national d´Histoire Naturelle, Paris, France. Christiane Amedegnato intensively studied Neotropical Orthoptera , and kindly helped us in studying this new genus, up to her last days.
