The composition and the seasonal variation of Pentatomoidea (Hemiptera) were evaluated between September 2005 and August 2006 in three fragments of Atlantic Forest in the southern region of the State of Santa Catarina (Brazil): Parque Ecológico José Milanese (Criciúma, 28º41'23''S, 49º25'55''W), Parque Ecológico de Maracajá (Maracajá, 28º52'51''S, 49º27'59''W) and Balneário Morro dos Conventos (Araranguá, 28º56'05''S, 49º21'47''W). Monthly sampling had been carried out in the three areas, using beating tray and sweeping nets to sample forest edge vegetation. After an effort of 108 hours, 595 individuals of 4 families, 29 genera and 49 species. were collected. Pentatomidae was the most abundant family (82.69%), followed by Cydnidae (15.97%), Scutelleridae (0.84%) and Tessaratomidae (0.50%). Pentatomidae also presented the greatest richness with 37 species. The most abundant species were Mormidea notulifera Stål, 1860, Oebalus ypsilongriseus (De Geer, 1773), Arvelius albopunctatus (De Geer, 1773), Edessa subrastrata Bergroth, 1891, Galgupha schulzii (Fabricius, 1781) and Agroecus scabricornis (Herrich-Schäffer, 1844). More individuals were captured between the end of the spring and the beginning of autumn, representing 71.76% of the total collected. Parque do Maracajá presented significantly higher abundance and richness. This study portrays the first inventory of the diversity of Pentatomoidea in natural habitats in the State of Santa Catarina.
