CONTRERAS, María Angélica et al. New records of phlebotomine sand flies (Diptera: Psychodidae) near the Amoya River in Chaparral, Tolima. Biomédica [online]. 2012, vol.32, n.2, pp.263-268. ISSN 0120-4157.

Introduction. In Colombia, the diversity of phlebotomine sand flies is high, with 162 recorded species, and which include vectors of Leishmania spp. Objective. To identify the sand fly species of medically importancein the area of influence from Amoyá River Hydroelectric Project, Colombia. Materials and methods. Sand flies were collected with CDC lighttraps, Shannon traps and sticky traps, from 15 villages in Chaparral County,Tolima. Results. A total of 1,077 adult sand fly specimens were collected. Thirteen species were found in the genus Lutzomyiaand one species in the genusWarileya.Among the Lutzomyia species, three species--Lutzomyia longiflocosa, Lutzomyia columbianaandLutzomyia nuneztovari--are important for their epidemiological history.Lutzomyiasuapiensiswas a new record for Colombia, and Warileya rotundipennis was recorded for the first time in Tolima. Conclusions. This study contributed to an increased knowledge of Colombian sand flies in terms of (1) expanding the geographical distribution of members of the subfamily Phlebotominae, (2) gaining estimates of species-richness and species associations in central Colombia, and (3) providing a better understanding of epidemiology of leishmaniasis in theChaparral area.
