Resumo

Lutzomyia fraihai (Martins, Falcao \& Silva 1979), described from Tres Bracos municipality (Bahia state, Brazil), is closely related to Nyssomyia yuilli yuilli (Young \& Porter, 1972), described from Rio Anori, Antioquia, Colombia. The former species, despite the morphological differences reported by its authors, was included as a junior synonym of Ny. yuilli yuilli, and this status has been accepted by sand fly-taxonomists. However, we had an opportunity to examine both taxa, and a clear difference was noted in their male genitalia. In this study, the morphometric/morphologic characters of specimens that had been identified as Ny. yuilli yuilli from different localities (Brazil, Peru, Colombia, Bolivia) and type material of both Ny. yuilli yuilli and Lu. fraihai were analyzed. The results revealed that males from Brazil (Bahia, Acre, Para, and Rondonia states) and Peru present statistically significant differences in the ratio between paramere rectangular and digitiform areas as well as for the cercus length and width of the aedeagal ducts tips, when compared with the type specimens of Ny. yuilli yuilli, but are statistically similar to those characters of Lu. fraihai. However, females of the two species are indistinguishable. Thus, based on the male morphology, Ny. fraihai stat. rev. n. com. was resurrected from the synonymy of Ny. yuilli yuilli. The specimens from the Atlantic forest biome and the Amazon biome in Brazil, Peru, and Bolivia in fact belong to Ny. fraihai. This species presents a cis-Andean distribution, while Ny. yuilli yuilli has been found in both Andean and Trans-Andean areas. (AU)
