List of species in the genus Lutzomyia , França , 1924 ( Psychodidae , Phlebotominae ) from the State of Mato Grosso Lista das espécies do gênero Lutzomyia , França , 1924 ( Psychodidae , Phlebotominae ) do Estado de Mato Grosso

This work had the objective of listing the sand fly species that occur in the State of Mato Grosso, Brazil. Data relating to entomological surveys conducted between 1996 and 2004 were obtained from the National Health Foundation and the State Health Department, and this was supplemented with information from research carried out in the state and from the specialized literature. There were records of 106 sand fly species belonging to the genus Lutzomyia. This is a rich and diversified fauna, with some species restricted to forested areas and others recorded throughout the state, independent of the vegetation type, and in areas modified by human action, with predominance of Lutzomyia whitmani. Key-words: Lutzomyia. Sand fly fauna. Mato Grosso.

Among the entomological research carried out in the State of Mato Grosso, Aguiar  Studies on the geographic regions where sand flies occur contribute towards better comprehension of the epidemiological aspects of leishmaniasis.The present study had the objective of listing the sand flies species that occur in the State of Mato Grosso.

MATERIAL AND METHODS
The State of Mato Grosso is situated in the central-western region of Brazil, with an area of 903,358 square kilometers, and it has 2,803,274 inhabitants 7 .Mato Grosso forms the watershed between the Plate and Amazon Basins, the two biggest hydrographic basins on the continent and it contains three of the most important Brazilian vegetation zones: the Amazon forest, the savanna and the Pantanal marshland.The annual rainfall distribution shows the tropical character of the area, with two well-defined seasons: one dry and the other wet 7 .
Mato Grosso is considered to be the biggest agricultural expansion frontier in Brazil.Over the last few years it has defined the process of internal development in Brazil.The occupation of economic space, in terms of both the migrants becoming established as smallholders in settlement projects and the big agricultural and pastoral companies, has consolidated the position of Mato Grosso as the Agricultural State 7 .
The present study consists of a report on species of the genus Lutzomyia that occur in the State of Mato Grosso.The data were mainly obtained from the National Health Foundation's Regional Coordination Office for Mato Grosso (FUNASA/CORE/ MT) and from the Entomology Laboratory of the Vector and Anthropozoonosis Surveillance Directorate, Environmental Health Surveillance Coordination Office, Health Surveillance Superintendency, State Health Department (SES/MT).These data related to an entomological survey that was developed between 1996 and 2004, as identified by Young and Duncan 15 , and were supplemented with information from studies carried out in the state and from the specialized literature.This is a rich and diversified fauna, with some species restricted to the forested areas, while others are recorded all over the state, independent of the vegetation zone, and in areas modified by human action.
The visceral leishmaniasis vector, L. longipalpis, is a very eclectic species in relation to its dietary habits, with high ecological valence.It can therefore adapt to environments with diverse characteristics and inhabit ecosystems going from hostile dry regions to areas modified by human action 6 , and from coastal regions to exposed locations 10 .L. cruzi, which has been implicated as vector for Leishmania chagasi in Mato Grosso do Sul 8 14 , with widespread distribution across the state.
The species L. whitmani, which presents widespread uniform distribution in the state and has been recorded both within and around homes, is probably the best-adapted species 12 13 .L. antunesi is prevalent in the forest canopy 2 .L. migonei is found in wetter areas 6 and is a species found in all five regions of Brazil 1 .It has been observed in Mato Grosso, in areas with all types of vegetation.L. flaviscutellata has been recorded in these same areas and, although it is considered extremely wild, it has moved into areas around and inside homes, thus indicating differentiated behavior, as observed by Rebêlo et al 10 .
Lutzomyia intermedia is considered to be the most important vector for cutaneous leishmaniasis in southeastern Brazil and it occurs in the states neighboring Mato Grosso, such as Tocantins, Goiás, Federal District and Mato Grosso do Sul 1 .L. ayrozai is predominantly found in areas around homes and in areas adjacent to forests 6 .It occurs in all of the vegetation types in Mato Grosso, excepted in the marshland.
According to Aguiar and Medeiros 1 , L. carrerai carrerai and L. yuilli yuilli occurs in all of the Brazilian regions, except for the southern region, while L. anduzei is found in the northern, northeastern and central-western regions.These species present distribution in all the vegetation types, with exception of marshland.L. gomezi has the same occurrence as L. anduzei and has been observed exclusively in forest areas, while L. tuberculata is in forest and savanna.
The species L. complexa, L. olmeca bicolor, L. olmeca nociva, L. ubiquitalis and L. umbratilis are important vectors in the Amazon region, occurring in forest, transition and savanna areas, except for L. olmeca nociva, which has only been observed in the savanna.
We can communicate that this is the first record of L. clitella in Brazil, and the specimen is stored at the International Phlebotomine Reference Center at the René Rachou Research Center, Fundação Oswaldo Cruz, in Belo Horizonte City, Brazil.
