The family Psychodidae has a cosmopolitan distribution with members that occur in many habitats, mainly humid environments, and is most diverse the tropics. Subfamilies Sycoracinae Phlebotominae have females hematophagous habits latter studied more due to medical veterinary interest, since it includes species can transmit diseases animals humans. knowledge about sand fly fauna region extremely ...

This paper describes sand flies similar to Nyssomyia intermedia (Lutz & Neiva) with variations in the number of spines at the gonostyle and tests the hypothesis whether these specimens belong or not to N. intermedia species. Using Principal Component Analysis and Neighbour Joining, the measurements of 15 structures of the phlebotomine with variations in number of spines were compared with measu...

The male genitalia of Lutzomyia (Lutzomyia) renei (Martins, Falcão & Silva, 1957) have four bristles, three fine and one semi-foliaceous, inserted basomesally on the gonocoxite. Nonetheless, in the original description and in other taxonomic studies, these bristles have been illustrated and described in varying formats. In order to clarify the morphology of this species, both sexes are here red...

BACKGROUND There are nearly 1000 species of Phlebotomine sand flies in 6 genera, of which only two, Phlebotomus in the old world and Lutzomyia in the new world are medically important. Globally, leishmaniasis prevalent in 98 countries and affects estimated 12 million people with almost two million new cases per year. Some rural areas of Azarshahr District in East Azarbaijan Province have been r...

The morphology of the spiracles of fourth instar larva in eight sandfly species were examined by light and scanning electron microscopy. Species studied were: Lutzomyia longipalpis (Lutz & Neiva), L. ovallesi (Ortiz), L. youngi Feliciangeli & Murillo, L. evansi (Nuñez-Tovar), L. trinidadensis (Newstead), L. migonei (França), L. absonodonta Feliciangeli, and L. venezuelensis (Floch & Abonnenc). ...

The geographical distribution of Phlebotomine sandflies of the Lutzomyia intermedia complex is presented, based in collections for this study and in personal informations from other workers and bibliography. The subject is discussed, in relation to climate and to altitude and latitude. Lutzomyia intermedia s.s. was found in smaller altitudes and latitudes than Lutzomyia neivai; the last species...

Lutzomyia georgii n. sp. and the female of L. tarapacaensis in the Series infraspinosa of the subgenus Evandromyia are described, from specimens collected in rainforest in the north of the State of Pará, Brazil. The new species was taken together with five other Evandromyia species including L. infraspinosa (sensu strictu) in the same locality. L. georgii has previously been confused with both ...
