Within the sand fly genus , the species group contains several of the principal vectors of American cutaneous leishmaniasis and human bartonellosis in the Andean region of South America. The group encompasses 40 species for which the taxonomic status, phylogenetic relationships, and role of each species in disease transmission remain unresolved. Mitochondrial () phylogenetic analysis of a 667-bp fragment supported the morphological classification of the group into series. Genetic sequences from seven species were grouped in well-supported monophyletic lineages. Four species, however, clustered in two paraphyletic lineages that indicate conspecificity—the pair and the pair. sequences were also evaluated as a taxonomic tool based on interspecific genetic variability within the group and the intraspecific variability of one of its members, , across its known distribution.
