Lutzomyia
''Lutzomyia'' is a genus of Phlebotominae, phlebotomine Sandfly, sand flies consisting of nearly 400 species, at least 33 of which have medical importance as Vector (epidemiology), vectors of human disease. Species of the genus ''Lutzomyia'' are found only in the New World, distributed in southern areas of the Nearctic realm, Nearctic and throughout the Neotropical realm. ''Lutzomyia'' is one of the two genera of the subfamily Phlebotominae to transmit the Leishmania parasite, with the other being ''Phlebotomus'', found only in the Old World. ''Lutzomyia'' sand flies also serve as vectors for the bacterial Oroya fever, Carrion's disease and a number of arboviruses. Evolution The genus, named after Adolfo Lutz, is known from the extinct Burdigalian (20–15 Mya (unit), mya) species ''Lutzomyia adiketis'' found as a fossil in Dominican amber on the island of Hispaniola.

Lutzomyia Longipalpis
''Lutzomyia longipalpis'' (''L. longipalpis'') is a species complex of sand fly, sandfly belonging to the family Psychodidae. This species is primarily present in Central America, Central and South America, but has also appeared in Mexico. There have been reports of ''L. longipalpis'' as far south as Argentina, as they are found in a wide variety of ecological conditions. Both males and females feed on sugars from plants and aphids, but only adult females feed on the blood of other mammals. The species has recently begun appearing in urban areas throughout Brazil, and serves as a key vessel for the propagation of the parasite ''Leishmania infantum''. The presence of these flies appears to be strongly correlated to the presence of domestic chickens in Latin America. The first major urban outbreak of the lethal ''Visceral leishmaniasis, Visceral leishmanias'' epidemic was detected in Teresina, Piauí State in the early 1980s following a massive planting of acacias.Lima, L., Mesquita, ...
