“…Phylogenetic analysis (MP) reveals close relationships among populations in the Brazilian highlands (Lapinha Cave), the Amazon (Salvaterra and Santarem), San Francisco Basin (Jacobina) and Brazilian scrubland (Baturité). These results are concordant with patterns of divergence in the nuclear genome (isozyme variation) among the same Brazilian populations, with the exception of the population at Roraima, that was not included in the isozyme studies (Mukhopadhyay et al, 1998;Mutebi et al, 1999;Azevedo et al, 2000). These authors concluded that populations in Brazil represent a single species, but with relatively high levels of genetic divergence among local populations.…”

“…This fact had been observed when the same character was analyzed in L. (L.) longipalpis (Azevedo et al 2000) and in other species, principally from the Nyssomyia and Psychodopygus sub-genera. The character frequently varies extensively among individuals from the same species, and its importance is thus doubtful in diagnosis.…”

“…In recent years, morphometry has been used as a taxonomic tool to help and elucidate the systematic identity of several sand ßy species (Marcondes 1996, Rangel et al 1996, Azevedo et al 2000. This project, therefore, has focused on morphological and morphometric studies of different populations of L. (N.) umbratilis in Brazil and Venezuela to assess the degree of inter-or intrapopulation heterogeneity.…”

We analyzed 64 quantitative and qualitative morphological characters in different populations of Lutzomyia (Nyssomyia) umbratilis Ward & Fraiha from Venezuela (Gran Sabana, Bolívar/BO) and Brazil (Serra do Navio, Amapá/AP Manaus, Amazonas/AM, Monte Dourado, Pará/ PA, and Peixoto de Azevedo, Mato Grosso/MT). Based on an analysis of qualitative characters, no differences were observed that could distinguish between the populations. Parametric tests were used to verify differences between sample means and variance homogeneity. The analysis-of-variance (ANOVA) test showed the existence of differences between character means in the five populations. In the graphic representation of the Student-Newman-Keuls test (Student-Newman-Keuls), we observed that 77% of the analyzed characters displayed disjunctions between the Venezuelan and Brazilian populations. Considering only the Brazilian population averages, we concluded that they are statistically different. When the Student-Newman-Keuls test was applied, no pattern was found that could separate them. However, in part, the phenetic analysis showed some evidences of heterogeneity in MT population.

Lutzomyia longipalpis (Diptera: Psychodidae: Phlebotominae), the main vector of visceral leishmaniasis in the Americas, is a putative species complex. Molecular polymorphism was characterized in a 266 bp fragment of L. longipalpis homologous to period, a 'speciation gene' from Drosophila. Samples from the Brazilian localities of Jacobina (BA), Lapinha (MG) and Natal (RN) were analysed and the data indicate that the three populations are highly differentiated, with a very low level of gene flow between them. These results are in agreement with published pheromone and copulation song studies that suggest the existence of a sibling species complex in Brazil.
