Abstract

BEJARANO, Eduar Elías et al. New Records of Phlebotomine Sand Flies (Diptera: Psychodidae) at Sierra Nevada de Santa Marta, Colombia. Acta biol.Colomb. [online]. 2015, vol.20, n.1, pp.221-224. ISSN 0120-548X.  http://dx.doi.org/10.15446/abc.v20n1.45176.

Phlebotomine sand flies, vectors of leishmaniasis, have not been well studied in the Sierra Nevada de Santa Marta, and likewise, are not well known in other regions of the Department of Magdalena, Colombia. To date only thirteen species of Lutzomyia have been recorded as occurring in the Department. The present note adds three species and includes an additional subgenus. Collections were made in the lower foothills of the Sierra Nevada de Santa Marta at elevations ranging from 117-130 m in the communities of Seywiaka, Las Tinajas and Calabazo. Eighty-four percent of the 885 phlebotomines sand flies collected were obtained from CDC light traps, 11 % from Shannon trap and 5 % from typical resting sites using an electric aspirator. The following nine species were identified from the collections: Lutzomyia gomezi, Lu. panamensis, Lu. trinidadensis, Lu. carpenteri, Lu. evansi, Lu. dysponeta, Lu. dubitans, Lu. shannoni, and Lu. micropyga. The most abundant species were Lu. gomezi and Lu. panamensis, which, respectively, accounted for 69 % and 14 % of the specimens. Of the nine species, Lu. carpenteri, Lu. dubitans and Lu. dysponeta represent new records for the Department of Magdalena. Also, a few female specimens were encountered of a species belonging to the Lu. osornoi series of the subgenus Helcocyrtomyia, which represents the first record of this subgenus in the Caribbean region of Colombia.
