Résumé
ABSTRACT Although the species richness of Stratiomyidae (Diptera) in Brazil (~340 species) is one of the highest for the family worldwide, we still do not know the actual number of species, the extent of their distribution, or the species seasonal dynamics for a single area in the Neotropics. The soldier fly fauna in the semideciduous seasonal forests, which cover a major area of the countryside of the state of São Paulo, is poorly known compared to the best-known areas in the Atlantic Forest for stratiomyids, such as the ombrophilous forests on the southeast coast. With the constant habitat fragmentation of the remnants of the semideciduous forests in the state for crops and pastures for cattle, we are losing valuable data about biodiversity. This study details the stratiomyids for a single area in the Neotropical Region, using a standardized collecting methodology with Malaise traps, from May 2010 to December 2011. Here, we provide a list of 41 stratiomyid species and 25 genera in eight subfamilies from a total of 1,533 specimens collected in the Reserva Biológica e Ecológica Augusto Ruschi, Sertãozinho, Brazil. The current number of species/morphospecies reported for the state of São Paulo is raised to 113, with Merosargus golbachi James, 1971 in James and McFadden, 1971 and M. tripartitus James, 1971 in James and McFadden, 1971 reported for the first time to Brazil. Our analyses estimate even higher richness in the studied area, probably between 48 to 114 species, indicating that further collection efforts are needed.

Fauna de Campopleginae (Hymenoptera, Ichneumonidae) em hortas orgânicas em Araraquara e São Carlos, SP, Brasil. De março de 2006 a fevereiro 2007 foram realizadas doze amostragens utilizando armadilhas Malaise em cada uma das três áreas de cultivos orgânicos estudadas. Um total de 1773 espécimes foram identificados em dez gêneros de Campopleginae: Campoctonus Viereck, 1912, Campoletis Föster, 1869, Casinaria Holmgren, 1859, Charops Holmgren, 1859, Cryptophion Viereck, 1913, Diadegma Föster, 1869, Dusona Cameron, 1900, Hyposoter Förster, 1869, Microcharops Roman, 1910 e Venturia Schrottky, 1902. A riqueza e diversidade de gêneros foram semelhantes nos locais amostrados. Verificou-se baixa uniformidade, sendo Campoletis, Venturia e Casinaria os gêneros mais comuns e abundantes.
Campopleginae (Hymenoptera, Ichneumonidae) fauna in organic crops in Araraquara and São Carlos, São Paulo State, Brazil. From March 2006 to February 2007 twelve samples were performed using Malaise traps in each of the three studied organic crop areas. A total of 1773 specimens were identified in ten Campopleginae genera: Campoctonus Viereck, 1912, Campoletis Föster, 1869, Casinaria Holmgren, 1859, Charops Holmgren, 1859, Cryptophion Viereck, 1913, Diadegma Föster, 1869, Dusona Cameron, 1900, Hyposoter Förster, 1869, Microcharops Roman, 1910 e Venturia Schrottky, 1902. The richness and diversity of genera indices found were very similar. A low evenness was observed with Campoletis, Venturia and Casinaria being the most common and abundant genera.
