Abstract

Chinavia Orian (1965) is one of the most diverse genera of Pentatomidae, distributed in the Afrotropical, Neotropical and Nearctic Regions. Thirty-two species are recorded for Brazil, some of thempotential economic impact because they are found on crops and referred to as pests. The morphology of the five nymphal instars of C. armigera (Stål, 1859), C. aseada (Rolston, 1983), C. brasicola (Rolston, 1983) and C. runaspis (Dallas, 1851) are described here. Through a comparative study, identification keys were developed to allow an early identification of the 12 Chinavia species of Rio Grande do Sul.
