Introduction. Since entomological surveillance is the main control strategy for visceral leishmaniasis, updated information on the distribution and ecology of involved vector species is necessary for planning preventive measures. Objective. To present the updated and geo-referenced distribution of L. longipalpis and L. evansi, vectors of visceral leishmaniasis in Colombia, considering their relationship with their habitat. Materials and methods. Distribution was estimated from records of the sand fly specimens collected since 1967.The information was organized in a database from which the localities were selected and geographically analyzed with Arc view in order to develop the distribution maps. Results. 40 localities were established for L. longipalpis along the upper (24), middle (11) and lower (5) Magdalena river valley . L. evansi was recorded in 19 localities of the middle (5) and lower (14) Magdalena valley. Conclusions. Both species showed consistent association with dry tropical forest ( sensu Holdridge 1967), confirming the epidemiological risk for visceral leishmaniasis in these areas.
