Mosquitoes (Culicidae) are diverse hematofagous insects distributed in tropical and subtropical areas of the world, occurring in wild environments as well as in rural and urban areas. One of the most relevant genus of Culicidae is genus Culex subdivided in 26 subgenera and 768 species. Genus Culex is a diverse group widely distributed in different faunistic regions of the world and it is worth noting that several species have been considered to be vectors of parasites and viruses. Within the genus Culex, the subgenus Melanoconion is documented as a group of species with documented wide distribution and great ecological adaptability. These species occur in wild and anthropic environments. Scientific evidences have shown that Melanoconion species are able to transmit emerging and re-emerging viruses (equine encephalitis and many arboviruses). Taxonomic and systematic studies about Melanoconion are scarce even though necessary given the great taxonomic difficulty that these insects represent. To facilitate the study of this subgenus the objective of the former research is to establish phylogenetic relationships among 32 species of Melanoconion. A multigenic approach will be applied to investigate the phylogenetic relationships of the Melanoconion species of Brazil. This methodology includes using DNA sequences of three nuclear genes and a mitochondrial gene (former barcode region); the chosen genes have been used previously in phylogenetic studies on culicid mosquitoes. With the species sequences phylogenetic trees will be estimated using three different methods. The taxonomic and phylogenetic value of the molecular markers will be evaluated and a taxonomic classification for subgenus Melanoconion of Culex will be proposed based on evidence of phylogenetic relationships.
