Instituto Oswaldo Cruz, Núcleo de Pesquisas, Brasil
In 1939, Mangabeira obtained, under laboratory conditions, the development of eggs of Phlebotomus brasiliensis Costa Lima, 1932, collected at Lassance (typical locality), Minas Gerais, Brasil. He then studied the female and immature stages of this Phlebotomus. The results of these observations plus some more recent data on the male, geographical distribution and bionomics are presented. Morphologically it is closest to Phlebotomus runoides. However, the male Phlebotomus brasiliensis differs from all other Phlebotomus because of its very long spicules, similar to those of Brumptomyia. The female differs by its longer ducts, and by possessing only four horizontal teeth in the buccal cavity, whereas P. runoides has approximately 12 teeth. The pupae of P. brasiliensis is characterized by its two pre-alar setae, which are very simple and small and by the abdominal setae, which are not planted on a protruding tubercle. The fourth stage larvae main characteristics are very thin antennae, inserted on a protruding tuberculum, and slightly brush-like hind frontal setae. P. brasiliensis is here reported, for the first time, for the State of Bahia (Cachoeira, Pojuca and Salvador). The species has almost always been found in armadillo burrows. In the State of Bahia it is more frequent during the dry season. Under laboratory conditions, the female lays about 53 eggs.
