| description | An epidemiological survey of the vectors of cutaneous leishmaniasis ("espúndia" type) was caried out in the Alto Beni region of Bolivia, an area of Andean foothills at the Eastern limit of the Amazonian lowlands. The climate is typical wet tropical (15ºS latitude). Anthropophilic phlebotomine sandfly species were sampled at 20 sites, all forested. The importance of species from the Psychodopygus group, already suspected as a vector in the transmission of Leishmania from the braziliensis complex, was confirmed by: 1) the aggressiveness and diversity of the species encountered (83% of catches, nine species), 2) the discovery of a new anthropophilic species, P. yucumensis and 3) the isolation of a strain of Leishmania braziliensis braziliensis indistinguishable from human strains from the same area, from two species, P. llanosmartinsi and P. yucumensis.<br>Uma pesquisa epidemiológica sobre os vetores da leishmaniose tegumentar (do tipo espúndia) foi empreendida na região do Alto Beni, na Bolívia, uma zona de contrafortes andinos no limite Este das baixas planícies amazônicas. O clima é tipicamente tropical úmido (15- de latitude Sul). As espécies de flebótomos antropofílicos foram amostradas em vinte estações, todas na floresta. A importância das espécies do grupo Psychodopygus, já suspeitas como vetores na transmissão da Leishmania do complexo braziliensis, foi comprovada por: 1) a agressividade e a variedade das espécies encontradas (83% das capturas e nove espécies); 2) a descoberta de uma nova espécie antropofílica, P. yucumensis e 3) o isolamento de uma amostra de Leishmania braziliensis braziliensis indistinguível das amostras humanas da mesma região, de duas espécies, P. llanosmartinsi e P. yucumensis. |
