title: "Cytochrome c oxidase I DNA sequence of Camponotus ants with different nesting strategies is a tool for distinguishing between morphologically similar species".
abstract: The great diversity of Camponotus, high levels of geographic, intraspecific and morphological variation common to most species of this genus make the determination of the interspecific limits of Camponotus a complex task. The Cytochrome c oxidase 1 (COI) gene was sequenced in this study to serve as an auxiliary tool in the identification of two taxa of Camponotus thought to be morphologically similar. Additionally, characteristics related to nesting were described. Five to fifteen workers from twenty-one colonies were analyzed, collected from twigs scattered in the leaf litter and from trees located in different regions of Brazil. Phylogenetic reconstructions, haplotype network, and nesting strategies confirmed the existence of two species and that they correspond to Camponotus senex and Camponotus textor. Our results emphasize that the COI can be used as an additional tool for the identification of morphologically similar Camponotus species.
