Abstract:		"The sand fly Lutzomyia cruzi (Mangabeira, 1938) is implicated as a vector of American visceral leishmaniasis (AVL) in some areas of Brazil. Lutzomyia cruzi is closely related to Lutzomyia longipalpis s.l. (Lutz and Neiva, 1912) the main Latin American vector of AVL and a species complex. Although females of the two species are identical, the males can be distinguished by differences in the genitalia. Nevertheless, pheromone analysis shows that Lu. cruzi males produce 9-methyl-germacrene-B, which has also been found in a number of Latin American populations of Lu. longipalpis s.l. In addition, analysis of microsatellite loci shows that the level of divergence between Lu. cruzi and Lu. longipalpis s.l. is similar to that observed among the Lu. longipalpis s.l. sibling species. Here we present the lovesongs of Lu. cruzi males which are similar to the Burst-type songs produced by one of the Lu. longipalpis s.l. sibling species. We also present data on the molecular polymorphisms of the period gene of Lu. cruzi that indicate this species as another sibling within the Lu. longipalpis complex. The results highlight the importance of an integrative approach to understand the patterns of genetic and phenotypic divergence among very closely related vector species"
