- Abstract: The genus Culex (Diptera: Culicidae) comprises approximately 763 valid species. It is one of the largest genera of Culicidae, but, it is one of the least known group. Identification of Culex mosquitoes based on morphological characteristics of the adult female can be difficult because many species belong to complexes, often with contrasted ecology, behavior and vector importance. In the present study the mitochondrial cytochrome oxidase I (COI) gene was examined for eight species belonging of three subgenera of Culex, with the objective of establishing phylogenetic relationship among these species and their subgenera. The phylogenetic relationships of Cx. (Microculex) imitator, Cx. (Culex) dolosus, Cx. (Culex) coronator, Cx. (Culex) nigripalpus, Cx. (Culex) mollis, Cx. (Culex) bidens, Cx. (Melanoconion) zeteki and Cx. (Melanoconion) aliciae, was inferred using the distance methods, the Neighbor Joining algorithm, under the Kimura 2-parameter model implemented in MEGA 4.0 software. Support for the groups was evaluated using distance bootstrap analyses with 500 replicates. The tree was rooted using the COI sequence of Anopheles nuneztovari. Results of the preliminary analyses showed that the sequences of species of the subgenera Culex, Microculex and Melanoconion clustered together in three distinct groups, agreeing with the morphological data. Cx. (Cx.) dolosus l.s. of two different localities showed high intra-specific variability, similar to two specimens identified as Cx. (Mcx) imitator l.s, corroborating morphological differences observed in male genitalia characteristics. Results of our analyses suggest that Cx, imitator and Cx. dolosus may comprise two distinct species. Using the COI sequence as a species barcode was suggested as an additional data for species identification and to solve taxonomic problems
