Lutzomyia is a genus of New World sandflies that transmit Carrion's disease (in Peru, Columbia, and Ecuador) and leishmaniasis (in tropical regions between northern Argentina and Texas). As is the case with mosquitoes, only the females suck blood.
In its cutaneous form, leishmaniasis manifests as large dermal lesions. Since these flies generally bite only those parts of the body not covered by clothing, the lesions, which develop in the vicinity of the bite and leave prominent scars, are disfiguring.
