Introduction. The epidemiological characteristics and the importance of the Lutzomyia species present in a leishmaniasis focus in the village El Hobo, Carmen de Bolívar, Department of Bolívar, Colombia, are described.. Objective. To obtain a preliminary assessment of leishmaniasis transmission in the village of El Hobo, Carmen de Bolívar. Materials and methods. Epidemiological data were analyzed and sandflies were collected with CDC traps and on protected human volunteers in the village of El Hobo. Sero prevalence of canine visceral leishmaniasis in dogs was evaluated using indirect inmunofluorescence (IFAT). Results. Nine Lutzomyia species were collected: L. trinidadensis, L. evansi, L. cayennensis, L. venezuelensis, L. gomezi, L. dubitans, L. ylephiletor, L. yuilli, and L. walkeri. The species of greater importance based on their implication in the transmission of cutaneous and visceral leishmaniasis were L. gomezi, and L. evansi respectively. Specimens of L. venezuelensis, L. dubitans, L. ylephiletor, L. yuilli, and L. walkeri are reported for the first time for the Department of Bolivar. The sero prevalence of visceral leishmaniasis in dogs was 36%. According to the epidemiological records, in 2002 the municipality of Carmen de Bolivar presented a 40% increase in cases of cutaneous leishmaniasis and an 80% increase in canine visceral leishmaniasis as compared to 2001, due to the outbreak in the village of El Hobo. Conclusions. The results indicate that the village of El Hobo is an area of potential risk for transmission of both cutaneous and visceral leishmaniasis.
