Lutzomyia (Nyssomyia) intermedia (Lutz & Neiva) is
redescribed, a neotype is designated, and a very similar
species, L. (N.) neivai (Pinto, 1926), is resurrected;
the male and the female are redescribed. The two species can
be differentiated by differences in the spermathecae, common
ducts and number of cibarial horizontal teeth of the females
and in the size and proportions of several structures of both
sexes. The known geographical distribution of both species is
given.
