The material studied comes from three of the several natural environments which still occur in Parana State. The samples were collected during the project PROFAUPAR, developed by Departamento de Zoologia, Universidade Federal do Parana. The selected sites were: Antonina (in the coastal plain), Sao Jose dos Pinhais (in the coastal mountain range) and Telemaco Borba (in the second plateau). During one year of the project, 2,106 specimens of Braconidae were collected with light trap. These wasps represented 21 subfamilies and 1,966 specimens were identified in 85 genera. Hormiinae, Rogadinae, Microgastrinae, Alysiinae, Doryctinae and Meteorinae were the most frequent subfamilies. Indices of diversity and evenness were used to discuss richness and dominance of genera in each locality. Statistical analyses indicated that the asymptote of actual genera richness have been approached only to Antonina and Telemaco Borba.
