A list of the stink bugs (Pentatomidae) species of the Brazilian Amazon is provided for the first time, based on literature review and identification of the specimens of Pentatomidae deposited in the entomological collection of the Museu Paraense Emílio Goeldi (MPEG).

Paraedessa, a new genus of Edessinae (Hemiptera: Heteroptera: Pentatomidae).

The new genus Paraedessa is proposed, to include four species previously placed in Edessa. The new genus is characterized by males with the pygophore showing a lateral expansion of proctiger, and females with gonocoxites 8 reduced; gonapophyses 8 exposed and sclerotized. The species are very similar and their identification is possible only by comparing genitalia.
