Lutzomyia longipalpis was found at the rural area named "Bairro do Arado", Salto de Pirapora County, São Paulo State, Brazil. This vector of visceral leihmaniasis is by the first time, surely recorded in the São Paulo State. The specimens were found in a chicken house built on rocks for observing the possibility of Triatoma arthurneivai colonization in artificial ecotopes. This suggests that the sandfly breeding places will possibly be found between or under the stones harbouring that triatomid bug. The necessity of epidemiological studies related to this found is emphasized.
