Phlebotomus oliverioi Barretto & Coutinho, 1941 foi originalmente descrita baseada em um único macho e desde então tem sido considerada sinônimo-júnior de Psathyromyia brasiliensis (Costa Lima, 1932). O estudo do holótipo de Ph. oliverioi nos levou a concluir que a cabeça deste espécime pertence ao gênero Psychodopygus e as asas, tórax e abdômen pertencem a Psathyromyia. Psathyromyia oliverioi não é uma espécie válida e deve ser removida da sinonímia e excluída de acordo com o recomendado pelo Código Internacional de Nomenclatura Zoológica (Artigos 17.2 e 23.8). O espécime foi medido, desenhado e fotografado e os caracteres morfológicos são discutidos. Lectótipo e paralectótipos são designados para Pa. brasiliensis.

Phlebotomus oliverioi Barretto & Coutinho, 1941 was originally described based only on the male holotype and has since been considered junior-synonym of Psathyromyia brasiliensis (Costa Lima, 1932). The study of the holotype of Ph. oliverioi allowed us to conclude that the head of this specimen belongs to the genus Psychodopygus and the wings, thorax and abdomen belong to a different species of Psathyromyia. Thus, Ph. oliverioi is a not valid species, and must be removed from the synonym and excluded from the provisions of the International Code of Zoological Nomenclature (Articles 17.2 and 23.8). The specimen was measured, drawn, photographed and the morphological characters are discussed. Lectotype and paralectotypes to Pa. brasiliensis are designated.

The phlebotomine sand fly fauna of the State of Minas Gerais is presented based on an extensive review of the literature. The fauna, which is a rich one, is currently known to consist of at least 93 species included in 16 genera. The genus Evandromyia (16 spp.) is the most representative one, followed by Micropygomyia (13 spp.), Psathyromyia (12 spp.), Brumptomyia (11 spp.), Pintomyia (9 spp.), Lutzomyia (7 spp.), Psychodopygus (7 spp.), Martinsmyia (4 spp.), Nyssomyia (3 spp.), Deanemyia (2 spp.), Expapillata (2 spp.), Pressatia (2 spp.), and Sciopemyia (2 spp.). The genera Bichromomyia, Trichopygomyia, and Migonemyia are represented by only one species. An updated list of phlebotomine sand fly species occurring in Minas Gerais is provided. Finally, the importance of the species of public health concern is discussed.

Foi realizada uma investigação sobre a fauna de flebotomíneos no município de Timóteo, MG, com a instalação de armadilhas do tipo New Jersey, em sete bairros, entre dezembro de 2005 e janeiro de 2006. O total de 2.289 espécimes de flebotomíneos foi registrado. Nyssomyia whitmani (Antunes & Coutinho) (48,1%), Nyssomyia intermedia (Lutz & Neiva) (36,8%) e Micropygomyia quinquefer (Dyar) (7,1%) foram as espécies mais abundantes. Algumas espécies de flo ebotomíneos incriminadas como transmissoras de Leishmania em Minas Gerais foram registradas e a importância destas para saúde pública é destacada. Neste trabalho faz-se o primeiro registro de Pintomyia bianchigalatiae (Andrade Filho, Aguiar, Dias & Falcão), Micropygomyia capixaba (Dias, Falcão, Silva & Martins), Micropygomyia schreiberi (Martins, Falcão & Silva) e Psathyromyia pascalei (Coutinho & Barretto) para Timóteo. Pressatia choti (Floch & Abonnenc) é registrada pela primeira vez para Minas Gerais.

An investigation of the phlebotomine sandfloy fauna in the municipality of Timóteo, Minas Gerais State, Brazil, was undertaken with New Jersey traps placed in seven neighborhoods from December 2005 to January 2006. A total of 2,289 phlebotomine sandfloy specimens were recorded. Nyssomyia whitmani (Antunes & Coutinho) (48.1%), Nyssomyia intermedia (Lutz & Neiva) (36.8%) and Micropygomyia quinquefer (Dyar) (7.1%) were the most abundant species sampled. Some sandfloy species that play a role in the transmission of Leishmania Ross in the State of Minas Gerais were recorded and their importance to public health is highlighted. Pintomyia bianchigalatiae (Andrade Filho, Aguiar, Dias & Falcão), Micropygomyia capixaba (Dias, Falcão, Silva & Martins), Micropygomyia schreiberi (Martins, Falcão & Silva) and Psathyromyia pascalei (Coutinho & Barretto) are recorded for the first time in the municipality of Timóteo, and Pressatia choti (Floch & Abonnenc) is recorded for the first time in the State of Minas Gerais.

Phlebotomine sand flies are often captured with human bait and/or light traps, either with or without an animal bait. More recently, synthetic attractants have been used as bait in traps to improve the capture of phlebotomine sand flies as well as other insects of medical and veterinary importance. The aim of the present study was to evaluate the effects of the kairomone 1-octen-3-ol (octenol) and the synthetic human odor BG-Mesh LureTM (BGML - lactic acid, caproic acid and ammonia) baited in modified CDC light traps on the capture of phlebotomine sand flies. The experiments followed the 5x5 Latin square design. Among the species caught, Lutzomyia intermedia apparently presented a dose-dependent response to octenol. The response obtained with the BGML, alone or in combination with octenol (5 mg/h), indicated some degree of attractiveness of these baits to different phlebotomine sand fly species. Octenol seems to be more attractive to L. intermedia than to Lutzomyia longipalpis, while the BGML presented a higher success in capturing L. longipalpis. When the components of the BGML were used separately, there was no increase in catching the female of L. intermedia. Apparently, there was no synergistic effect between the octenol and the BGML. In conclusion, the octenol and the BGML were demonstrated to be possible baits to attract some phlebotomine sand fly species.

Durante os meses de abril e maio de 2006 foram realizados experimentos em Brejo do Mutambal, município de Varzelândia, MG para avaliar a atratividade de flebotomíneos a cairomônios iscados em armadilhas luminosas do tipo CDC. Das 19 espécies do gênero Lutzomyia já registradas para a região, L. lutziana (Costa Lima), L. longipennis (Barreto), L. goiana (Martins, Falcão & Silva) e L. brasiliensis (Costa Lima) foram registradas pela primeira vez, aumentando a diversidade da fauna de flebotomíneos do município para 23 espécies. As espécies relatadas como primeiros registros e sua distribuição são citadas e discutidas.

During April and May 2006, experiments were carried out in Brejo do Mutambal, Varzelândia Town, Minas Gerais State, to evaluate the attractiveness of phlebotomine sandflies to CDC light traps, baited with kairomones. Of the 19 species of Lutzomyia already registered for the region, L. lutziana (Costa Lima), L. longipennis (Barreto), L. goiana (Martins, Falcão & Silva) and L. brasiliensis (Costa Lima) were recorded for the first time, thus increasing the diversity of phlebotomine sandflies fauna in this area to 23 species. The new registered species and distribution are shown and discussed herein.
