Natural infections with Leishmania were found in females of the phlebotomine sand flies Lutzomyia neivai (Pinto) (=Nyssomyia neivai) and Lutzomyia sallesi (Galvão & Coutinho) (=Evandromyia sallesi) (Diptera: Psychodidae) from Lassance, in the Brazilian state of Minas Gerais. Promastigotes were found in the pyloric region of the former species and in the abdominal midgut of the latter species. Insects found to be infected by microscopic examination were macerated in saline solution and inoculated into hamsters. Subsequent analysis by polymerase chain reaction-restriction fragment length polymorphism revealed both isolates to belong to the species Leishmania infantum chagasi Cunha & Chagas.
