Figure 1. Neighbour-joining phylogram of bacterial 16S sequences obtained from field collected Lutzomyia species.

Numbering refers to clones described in Table 1. Bacterial species from Lapinha (Minas Gerais-Brazil) are presented in purple; species identified from sand flies collected in Alagoas (Brazil) are presented in green; species identified in Corumbá (Brazil) are presented in pink and red represents bacterial species identified from Lu. longipalpis collected in Callejón (Colombia). Bacterial sequences extracted from Genbank for comparison are presented in black.
