On the genus Chinavia orian: additions to the descriptions of three species (Hemiptera: Pentatomidae).

Chinavia Orian has 79 nominal species, 32 of them occur in Brazil, and intraspecific chromatic or morphological variations are known for both immatures and adults of some species. Additions to the descriptions of Chinavia difficilis (Stål), Chinavia geniculata (Dallas), and Chinavia obstinata (Stål) are provided in here, and corrections are proposed for the pictorial key by Schwertner & Grazia for the Brazilian species of Chinavia. New distribution records are also given for the first two species.
