Thirty-five species of Lutzomyia and two species of
Brumptomyia were identified among 795 phlebotomines taken in
light-traps near the upper reaches of the middle Rio Negro. The subgenus
Psychodopygus predominated in number of species (11) and relative
abundance (74-81% in light trap samples from the forest and 99% on human
bait). For many of the species these records help to fill large gaps on
current maps of distribution, and for others (L. olmeca nociva, L.
mangabeirana, L. triacantha) the findings represent a significant
expansion of their known range. A new species in the subgenus
Psychodopygus (L. douradoi) is described from both sexes,
and L. bettinii is recorded for the first time in Brazil. {P}
