The sand fly Lutzomyia (Lutzomyia) elizabethrangelae sp. nov. is described and illustrated based on the morphological characters of male and female specimens captured in sandstone caves in the municipality of Palmeirópolis, in the southern region of Tocantins state. The samples were collected as part of an entomological vector-monitoring project during the construction of the Peixe Angical Hydroelectric Plant. Based on the morphological characters of the new species, we believe this species can be included in the subgenus Lutzomyia. This species is closely related to two others, Lutzomyia forattinii Galati et al. 1985 and Lutzomyia almerioi Galati and Nunes 1999. The new species can be distinguished from Lutzomyia forattinii and Lutzomyia almerioi by the morphological characteristics of the male genitalia and the female cibarium.
