Abstract

A new species from the southwest Brazilian Amazon, Isocopris rossinii Arias-Buriticá, Bach, and Vaz-de-Mello, new species, is described along with a diagnosis, illustrations, and discussion of its taxonomic position in the genus. This new species is readily distinguished by a deep depression in the frons, a large and trapezoidal ventral clypeal process in lateral view, a glabrous metaventral anterior lobe, the morphology of the aedeagus with triangular and symmetrical parameres, the presence of a subgenital plate, and large and asymmetrical lamellae copulatrix. Females show secondary sexual dimorphism, with the elytral striae widened from the first to the fourth in the central area. Here we present an updated key for the species of the genus Isocopris Pereira and Martínez, 1960.
