Acyphus Heller is a monotypic genus revised by Lanteri & del Río (2006). The single species, A. renggeri, includes three different morphotypes: A) the typical one, with pale nebulose scaly pattern and two pairs of dense irregular maculae on the elytra; B) with pale nebulose scaly pattern but lacking pairs of irregular maculae on elytra; and C) lacking distinct scaly vestiture on the elytra. Males are only known from Formosa and they are all devoid of scales.
Prosopis affinis Spreng. (=Prosopis algarrobilla Griseb., Prosopis nandubey Lor. ex Griseb.) and Prosopis torquata (Cav. ex Lag.) D.C. The former is a deciduous tree distributed in northeastern Argentina (Buenos Aires, Chaco, Córdoba, Corrientes, Entre Ríos, Formosa, Santa Fe and Santiago del Estero provinces), southern Bolivia, southwestern Brazil, Paraguay, Perú and Uruguay (Burkart 1976), area that approximately corresponds to the geographic distribution of Acyphus. In Buenos Aires province A. renggeri was found on Thalia sp (Marantaceae) and Acacia caven Mol. (Fabaceae) commonly called “espinillo”.

Associated with native trees of the family Fabaceae (legumes), typical of the Chacoan and Espinal biogeographic provinces.
