LLANO, E.G et al. Identificación rápida de Lutzomyia longipalpis a partir de cinco descriptores del aparato genital masculino. Rev. vet. [online]. 2013, vol.24, n.1, pp.21-24. ISSN 1669-6840.

The phlebotomus Lutzomyia longipalpis is considered the vector of canine visceral leishmaniasis. Specimens captured in Corrientes (Argentina) allowed the identification of the species Leishmania neivai, vector of cutaneous leishmaniasis, and Leishmania migonei and Leishmania cortelezzii-sallesi, both considered secondary vectors of cutaneous leishmanisasis. After insects gathering, next step was the taxonomic identification of the different species of Lutzomyia by means of clearance of the anatomic structures and observation by light microscope, considering the characteristic descriptors for the species. There are approximately 30 descriptors used to identify L. longipalpis by microscopic observation of male genitalia. The aim of this study was to select fve descriptors of easy identification, which were in order of importance: differentiated setae of paramere, relationship between length of paramere and lateral lobe, shape and presence of coxite or basistilo, characteristics and location of the setae tuft and morphology of the coxite ejaculatory pump. These descriptors allowed and easy visualization and rapid taxonomic identification for the species.
