Phlebotomine sand flies from Säo Gabriel da Cachoeira (State of Amazonas, Brazil) with a description of Lutzomyia (Psychodopygus) douradoi n.sp. (Diptera: Psychodidae)

ABSTRACT

Third-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 predominanted in number of species (11) and relative abundance (74-81 per cent in light trap samples from the forest and 99 per cent 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. bettini is recorded for the first time in Brazil.
