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.

É descrito o macho de Chlorotabanus leucochlorus Fairchild, 1961, espécie com registros para o norte do Brasil, Suriname, Venezuela e leste do Peru. Para o estudo foram utilizados sete machos provenientes de diferentes localidades do estado do Amazonas, Brasil. O material está depositado na Coleção de Invertebrados do Instituto Nacional de Pesquisas da Amazônia (INPA) e na Coleção Zoológica Paulo Bührnheim (UFAM), ambas em Manaus, Brasil.

Immature stages and male adult of Leucotabanus albovarius (Walker, 1854) are described and figured for the first time. The larva was found in rotten wood of the palm Bactris gasipaes Kunth (Arecaceae) near Manaus. Differential diagnoses of the known immatures of Leucotabanus Lutz are presented.
