Specimens belonging to four families of Heteroptera (Pentatomidae, Coreidae, Alydidae and Rhopalidae) were collected from a protected area in the Paraná Forest in Argentina. The assemblages were characterized and the biodiversity estimated by family. Abundance, relative abundance, richness, singletons, doubletons, and diversity indices were calculated. We constructed species rarefaction curves based on accumulation of specimen richness and abundances, and rank-abundance curves, and we considered the performance of seven richness estimators using EstimateS v.9.1. Pentatomidae had the greatest richness and diversity; Coreidae was the second most diverse family, with highest sampling deficit, highest percentage of singletons, and lowest inventory completeness; and Rhopalidae was the best sampled family with asymptotic rarefaction curves. We compared our Pentatomidae assemblage to those of five protected areas in the Brazilian Atlantic Forest. Beta diversity was measured among areas by indices that show similarity/dissimilarity between habitats in terms of species composition. The information on Pentatomidae species in each area was used to calculate the Species Conservation Importance index (SCI), the Average Species Conservation Importance (ACI), and then to assess the Site Conservation Values (SCV). We found similar SCV among the six areas and noted that the use of criteria was limited by the lack of information, being crucial to increase the knowledge of most of the species. As next step we will focus in the PN Rio Pilcomayo, a protected area located in the Humid Chaco in Argentina, and we will also work focus on adding collecting methods to access to the geophilic fauna of Heteroptera.
