A mosquito faunal survey was conducted from October 2010 to February 2011 in the municipal parks of São Paulo City, Brazil. A total of 7,015 specimens of 53 taxonomic categories grouped into 12 genera (Aedes, Anopheles, Coquilletidia, Culex, Limatus, Lutzia, Mansonia, Psorophora, Toxorhynchites, Trichoprosopon, Uranotaenia, and Wyeomyia) were collected. The largest and most peripheral parks showed greater species richness compared to smaller and more centralized parks.

Entre 2000 a 2004, foi realizado levantamento da fauna de Triatominae (Hemiptera: Reduviidae) e exame de infecção natural por Trypanosomatidae, no Estado de Mato Grosso do Sul. Um total de 13.671 espécimes foram capturados. Na análise faunística das espécies capturadas, Triatoma sordida foi caracterizada como muito abundante, muito freqüente, constante e dominante. Os índices de infecção natural para Trypanosoma cruzi apresentaram os valores de 3,2% para Panstrongylus geniculatus, 0,6% para Rhodnius neglectus e 0,1% para Triatoma sordida, apesar do Estado de Mato Grosso do Sul apresentar-se livre da transmissão vetorial endêmica.

Triatoma baratai Carcavallo & Jurberg, 2000, a species similar to Triatoma williami Galvão, Souza & Lima, 1967 andbelonging to the T. matogrossensis subcomplex, was described based on a male specimen collected in a sylvatic environ-ment, near a cave, in Bonito county, Bodoquena mountain range, state of Mato Grosso do Sul, Brazil. In the present workwe describe the female of T. baratai, captured in a chicken house, in Nioaque county, state of Mato Grosso do Sul, Brazil.Furthermore, we recorded the occurrence of T. baratai in domiciles and peridomestic environment in another four munic-ipalities (Bodoquena, Bela Vista, Corumbá, and Miranda), extending its geographical distribution. Finally, we present a key to the species of the Triatoma matogrossensis subcomplex.

Brazil. Results: This finding adds to the data on the geographical distribution of P. tertius from 14 to 15 known occurrences in Brazilian states and, therefore, reports the increase in the diversity of triatomines in Paraná. Conclusions: The presence of P. tertius in the state of Paraná demonstrates that the biodiversity of these insects may have been underestimated.
