The geographical distribution of Phlebotomine sandflies of the Lutzomyia intermedia complex is presented, based in collections for this study and in personal informations from other workers and bibliography. The subject is discussed, in relation to climate and to altitude and latitude. Lutzomyia intermedia s.s. was found in smaller altitudes and latitudes than Lutzomyia neivai; the last species seems to be better adapted to colder and drier climates than the first.
