Publicación Acceso abierto Anomalías morfológicas en diferentes estructuras de cinco especies de Lutzomyia (Diptera: Psychodidae).(Buenos Aires, Argentina: Revista de la Sociedad Entomológica Argentina, 2008., 2019-10-21) Vergara, Daniela; Bejarano, Eduar Elías; Vélez, Iván Darío; Sociedad Entomológica Argentina.Diverse morphological anomalies in fi ve different species of Lutzomyia França (Diptera: Pychodidae) are described and illustrated. These theratologies are observed in various structures important for the taxonomic identifi cation of the species. The different individuals that belong to the species L. columbiana, L. hartmanni, L. reburra, L. ayrozai and L. panamensis were captured in diverse departments in Colombia.Publicación Sólo datos Cambios teratológicos en flebotomíneos (diptera: psychodidae) del subgénero micropygomyia barretto, 1962(Universidad de Sucre, 2009-07-27) ESTRADA, LUIS; FLÓREZ, FERNANDO; BEJARANO, EDUARPublicación Acceso abierto Cambios teratológicos en flebotomíneos (Diptera: Psychodidae) del subgénero micropygomyia Barretto, 1962.(Sincelejo, Colombia : Revista Colombiana de ciencia animal - RECIA, 2009., 2019-10-15) Estrada, Luis G.; Flórez, Fernando; Bejarano, Eduar E.The taxonomic identification of the Phlebotominae associated with the epidemiological cycle of leishmaniasis is based on morphological characters of the adult insect. Teratologic changes in anatomic structures of taxonomic importance may eventually induce to errors in the species identification. Herein, we described the morphologic anomalies found in three species of the subgenus Micropygomyia Barretto, 1962. Insects were collected by using suction devices in the urban area of Sincelejo, Sucre, Colombia. Five spines were observed in males of Lutzomyia cayennensis cayennensis (Floch y Abonnenc, 1941), Lu. atroclavata (Knab, 1913), and Lu. micropyga (Mangabeira, 1942), and three spines in one male of Lu. cayennensis cayennensis.Publicación Acceso abierto Caracteres moleculares para la determinación taxonómica de tres especies de Lutzomyia (Diptera: Psychodidae), vectores potenciales de Leishmania presentes en el valle de Aburrá, Colombia.(Buenos aires, Argentina: Revista de la Sociedad Entomológica Argentina, 2008., 2019-10-18) Pérez Doria, Alveiro; Bejarano, Eduar Elías; Sierra, Diana; Vélez, Iván Darío; Sociedad Entomológica Argentina.To date, 143 species of Lutzomyia França are recorded in Colombia, but less than 7% is incriminated in the transmission of Leishmania spp. Alternative taxonomic characters are necessary to correctly identify the particular sand fl y fauna in each Colombian region, and the separation of morphologically similar vector and non-vector species. In order to detect useful molecular characters for the taxonomic determination of three potential vectors of Leishmania present in the Valle de Aburrá, Colombia, the present work sequenced the 3’ end of the mitochondrial cytochrome b gene in Lutzomyia hartmanni (Fairchild and Hertig), L. columbiana (Ristorcelli and Van Ty), and L. tihuiliensis Le Pont, Torrez-Espejo and Dujardin. Polymorphic sites, pairwise genetic distances (p), and entropy were determined from the multiple alignment of the nucleotide sequences. Numbers of silent and non silent substitutions were calculated from the amino acid sequences deduced from the nucleotide sequences of the gene. In the multiple alignment of the cytochrome b nucleotide sequences from Lutzomyia hartmanni, L. columbiana and L. tihuiliensis, 83 polymorphic sites were detected. A total of 18 amino acid replacements were found in the partial nucleotide sequences of the protein. Genetic distances varied from 0,137 between L. tihuiliensis and L. columbiana, to 0,215 among L. columbiana and L. hartmanni. Nucleotide and amino acid sequence polymorphisms within the cytochrome b gene and protein, respectively, constitute molecular characters potentially useful for the taxonomic determination of these sand fl y species.Publicación Acceso abierto Confirmación de la presencia de Lutzomyia Lutziana (Diptera: Psychodidae) en Colombia.(Bogotá, Colombia: Revista Caldasia, 2007., 2019-10-23) Bejarano, Eduar Elías; Duque, Patricia; Vélez, Iván DaríoThe presence of the sand fly Lutzomyia lutziana in Colombia is confirmed by one male specimen collected in the Serranía de La Macarena National Natural Park. This male was collected with a mouth aspirator, while resting in an armadillo nest. Lutzomyia lutziana resembles L. campograndensis, the former differing essentially by the slender tip of the genital filaments and the proportion of the length of the genital filaments and genital pump greater than 2,1.Publicación Acceso abierto DNA barcode for identification of immature stages of sand flies (Diptera: Psychodidae) collected from natural breeding sites.(Auckland, Nueva Zelanda: Revista Zootaxa, 2017., 2019-09-25) Vivero, Rafael José; Bejarano, Eduar Elías; Estrada, Luis Gregorio; Flórez, Fernando; Uribe Soto, Sandra; Yamileth Edgar; Estrada, Luis Gregorio; Ortega Gómez, Edgar; Torres Gutiérrez, Carolina; Muskus López, CarlosAlthough phlebotomine sand flies breeding sites have been identified and recorded by several studies, the microhabitats exploited by these insects remain little-known and hard to find. In this context, the difficulty of finding immature stages, and the limited number of taxonomic studies to identify immature stages of phlebotomine sand flies, are considered the major obstacles when attempting a complete inventory of Lutzomyia species. The objective of this study is to validate Cytochrome Oxidase I (Barcode region) as a marker for the identification of immature stages of Lutzomyia species recovered from natural breeding sites in Colombia. Among 142 collected sand flies, 18 immature individuals that did not complete their life cycle were identified to species level through sequencing of the COI gene. Values of K2P genetic distance between 0.002–0.031 allowed the identification of larvae at species level. The bootstrap support values (96%) in the Neighbor-Joining dendrogram were consistent for the majority of the established MOTUS of Lutzomyia atroclavata, Lutzomyia micropyga, Lutzomyia serrana, Lutzomyia cayennensis, Lutzomyia rangeliana, Lutzomyia shannoni and some species of the genus Brumptomyia. The COI gene is validated as a marker for the identification of immature stages of the genus Lutzomyia.Publicación Acceso abierto DNA barcoding to identify species of phlebotomine sand fly (Diptera: Psychodidae) in the mixed leishmaniasis focus of the Colombian Caribbean.(Países Bajos: Revista Acta Tropica, 2016., 2019-09-27) Romero Ricardo, Luis; Lastre Meza, Natalia; Bejarano, Eduar E.; Pérez Doria, AlveiroIdentification of the species of phlebotomine sand flies present in each focus of leishmaniasis is necessary to incriminate vectors and implement vector control strategies. Although the cytochrome oxidase I (COI) gene has been proposed as a barcode for the identification of animal species, less than 20% of New World phlebotomines have been characterized to date. In this study DNA barcoding was used to identify phlebotomine species of the mixed leishmaniasis focus in the Colombian Caribbean by means of three evolutionary models: Kimura’s two parameter (K2P) nucleotide substitution model, that of (Tamura and Nei, 1993) (TN93) and proportional sequence divergence (p-distances). A 681 bp sequence of the COI gene was obtained from 66 individuals belonging to 19 species of the genus Lutzomyia (Lu. abonnenci, Lu. atroclavata, Lu. bicolor, Lu. carpenteri, Lu. cayennensis cayennensis, Lu. dubitans, Lu. evansi, Lu. gomezi, Lu. gorbitzi, Lu. longipalpis, Lu. micropyga, Lu. migonei, Lu. panamensis, Lu. (Psathyromyia) sp., Lu. rangeliana, Lu. serrana, Lu. shannoni, Lu. trinidadensis and Lu. venezuelensis) and one of Brumptomyia (B. mesai).Publicación Acceso abierto Dos nuevos registros de Lutzomyia (Diptera: Psychodidae) para el Departamento de Risaralda, Colombia .(Bogotá, Colombia: Revista Colombiana de Entomología, 2007., 2019-10-22) Bejarano, Eduar Elías; Sierra, Diana; Vélez, Iván Darío; Sociedad Colombiana de Entomología .Two species of Lutzomyia sand flies are recorded for the first time in the department of Risaralda, Colombia: Lutzomyia atroclavata and Lutzomyia sp. series townsendi. The specimens of L. atroclavata were collected with a CDC light trap activated from 18:00 to 06:00 hours, whereas those of Lutzomyia serie townsendi were collected using human baits between 18:00 and 22:00 hours. The main diagnostic morphological characteristics of the species are described.Publicación Acceso abierto Estudio de los flebotomíneos (Diptera: Psychodidae) antropofílicos de la Serranía de La Macarena, Colombia.(Bogotá, Colombia: Revista Colombiana de Entomología, 2006., 2019-10-24) Bejarano, Eduar Elías; Duque, Patricia; Vélez, Iván Darío; Sociedad Colombiana de Entomología.A preliminary survey of the anthropophilic sand fly fauna of the Serranía de La Macarena, Colombia, is presented. Although leishmaniasis is endemic in the region, the vectors of the disease are yet unknown. Insects were collected in July and December using a mouth aspirator while they tried to bite humans between 18:00 and 22:00 hours. Ten species of Lutzomyia sand flies were identified from 89 female specimens collected: L. ayrozai, L. davisi, L. hirsuta hirsuta, L. carrerai carrerai, L. lichyi, L. amazonensis, L. sp. series squamiventris, L. yuilli, L. shawi, and L. sp. series townsendi. The subgenus Psychodopygus was most abundant, with six species that comprised 79.8% of all sand flies collected, followed by Nyssomyia with two species that constituted 16.9% of total captures. The verrucarum group and the subgenus Lutzomyia were each represented by one species. Finally, the epidemiological background of the species encountered are briefly reviewed.Publicación Acceso abierto Evidence for anthropophily in five species of phlebotomine sand flies (Diptera: Psychodidae) from northern Colombia, revealed by molecular identification of bloodmeals.(Reino Unido: Acta Tropica, 2015., 2019-11-06) Paternina, Luís E.; Verbel Vergara, Daniel; Romero Ricardo, Luís; Pérez Doria, Alveiro; Paternina Gómez, Margaret; Martínez, Lily; Bejarano, Eduar E.Identification of the bloodmeal sources of phlebotomine sand flies is fundamental to determining which species are anthropophilic and understanding the transmission of Leishmania parasites in natural epidemiological settings. The objective of this study was to identify sand fly bloodmeals in the mixed leishmaniasis focus of the department of Sucre, northern Colombia. In all 141 engorged female sand flies were analyzed, after being captured in intradomiciliary, peridomiciliary and extradomiciliary habitats with Shannon and CDC traps and by active searching in diurnal resting sites. Bloodmeals were identified by sequencing and analysis of a 358 bp fragment of the mitochondrial gene Cytochrome b (CYB) and a 330 bp fragment of the nuclear gene prepronociceptin (PNOC). Using both genes 105 vertebrate bloodmeals were identified, with an efficiency of 72% for CYB but only 7% for PNOC. Ten species of vertebrates were identified as providing bloodmeal sources for eight sand fly species: Homo sapiens (Lutzomyia evansi, Lu. panamensis, Lu. micropyga, Lu. shannoni and Lu. atroclavata), Equus caballus (Lu. evansi, Lu. panamensis and Lu. cayennensis cayennensis), Eq. asinus (Lu. evansi and Lu. panamensis), Bos taurus 4 (Lu. evansi, Lu. panamensis and Lu. c. cayennensis), Tamandua mexicana (Lu. shannoni and Lu. trinidadensis), Proechimys guyanensis (Lu. evansi, Lu. panamensis and Lu. c. cayennensis), Mabuya sp. (Lu. micropyga), Sus scrofa (Lu. evansi and Lu. gomezi) and Gallus gallus (Lu. evansi). Cattle, donkeys, humans and pigs were significantly more important than other animals (P = 0.0001) as hosts of Lu. evansi, this being the most abundant sand fly species. The five Lutzomyia species in which blood samples of human origin were detected included Lu. micropyga and Lu. atroclavata, constituting the first evidence of anthropophily in both species.Publicación Acceso abierto Flebotomíneos (Diptera: Psychodidae) antropofílicos de importancia en salud pública en Los Montes de María, Colombia.(La Habana , Cuba: Revista Cubana de Medicina Tropical, 2009., 2019-10-15) Cortés Alemán, Luis; Pérez Doria, Alveiro; Bejarano Martínez, Eduar ElíasLa leishmaniasis cutánea es una enfermedad endémica en Los Montes de María, Colombia, pero hasta la fecha se desconocían los flebotomíneos que pican al humano en el área. Los estudios previos realizados en esta zona se han orientado hacia la caracterización de los insectos que actúan como vectores en el ciclo epidemiológico de la leishmaniasis visceral, 6,12-17 porque esta última puede tener una evolución fatal. El objetivo de esta investigación fue determinar las especies de Lutzomyia que, por sus hábitos antropofílicos y antecedentes vectoriales, podrían desempeñarse como transmisores en el ciclo epidemiológico de la leishmaniasis cutánea en el área rural de Los Montes de María.Publicación Acceso abierto Flebotominos adultos e inmaduros (Diptera: Psychodidae): registros para el Caribe Colombiano.(Estado Aragua, Venezuela: Boletín de Malariología y Salud Ambiental, 2013., 2019-10-03) Vivero Gómez, Ortega Gómez, Edgar Rafael José; Aparicio Argumedo, Torres Gutiérrez, Carolina Yamileth; Muskus López, Bejarano Martínez, Eduar E. CarlosElaborating an inventory for Lutzomyia spp., without considering the immature forms of such insects, gives only a partial information about the species. Investigating immature phlebotomines represents a challenge and urgency especially in Leishmania spp. transmission areas. The objective of this study was to detect natural breeding sites, for an inventory of immature and adult phlebotomine community in the municipality of Colosó, Department of Sucre. Phlebotomine sandflies were collected between May and December of 2009, at the wild life experimental station in Colosó. Detection of immature stages was approached by direct visualization of soil and tree-substrate samples, incubation of substrate in laboratory conditions and use of emergence traps. Adult sampling was conducted by active diurnal search in resting places using bucal aspirators to collect the insects. Resting places were predominantly associated with tree trunks, such as holes in trunks and buttress roots. We collected 44 immatures of phlebotomine sandflies of which 32 belong to the following species: Lutzomyia migonei, Lu. dubitans, Lu. serrana, Lu. cayennensis cayennensis, Lu. micropyga, Lu. evansi, Lu. gorbitzi, Lu. ovallesi and Lu. shannoni. Also, up to 1231 adult individuals were collected and the most abundant species in descending order were Lu. evansi, Lu. micropyga and Lu. trinidadensis. The species Lu. migonei and Lu. gorbitzi are worth noticing given the fact that they represent new records for the Department of Sucre as well as the Caribbean Region in the country. It is necessary to include immature sampling as complementary information on phlebotomine surveys and in this way gather solid information to release proper species inventories with the remarks on potential vectors in leishmaniasis foci.Publicación Acceso abierto Frecuencia de uso de animales domésticos como fuente de alimentación de Lutzomya spp (Diptera: Psychodidae) en la vereda Toro, San Cayetano, Bolívar(Sincelejo : Universidad de Sucre 2017, 2018) Martínez Pérez, Lina Marcela; Alveiro José Pérez Doría; Universidad de SucreLa leishmaniasis es una enfermedad que involucra una amplia variedad de especies de parásitos, reservorios y vectores que están implicados en su transmisión. Los vectores presentan una preferencia alimenticia por vertebrados silvestres, domésticos y por el humano. Varias especies de vertebrados han sido identificados como reservorios de Leishmania spp., entre los que sobresalen roedores silvestres, zarigüeyas, perezosos, marsupiales y caninos. Sin embargo, aún se desconoce la preferencia alimenticia de la mayoría de especies de flebotomíneos, por lo que la determinación de las ingestas sanguíneas de los vectores de leishmaniasis puede proveer información valiosa relacionada con los patrones alimenticios de los flebotomíneos y una aproximación sobre las posibles predilecciones por alguna especie o grupo vertebrado en particular. El objetivo de este estudio fue determinar la frecuencia de uso de animales domésticos como fuente de alimentación de los flebotomíneos del género Lutzomyia asociados a la aparición de un caso de leishmaniasis visceral en la vereda Toro, San Cayetano, Bolívar. Para la captura de estos insectos se usaron trampas de luz LED emitida por diodos tipo CDC, ubicadas en cuatro sitios, que corresponden al peri y extra domicilio durante los días 5 y 6 de Mayo del año 2015. En total se encontraron 1.101 flebotomíneos con presencia de ingesta sanguínea en el tracto digestivo. Cada individuo fue identificado taxonómicamente, a cada flebotomíneo se le extrajo el material genético y se realizó un ensayo de identificación de fuentes de ingesta por PCR-múltiple del gen mitocondrial citocromo B (Cytb). Se encontró que Lutzomyia evansi fue la especie más abundante con un 99,82%. Con base en el tamaño de los amplicones obtenidos se encontró una frecuencia de uso de fuentes de ingesta del 16,73% (82/490), 16,32% (80/490), 12,45% (61/490), 11,63% (57/490), 9,79% (48/490) para humano, carnero, cerdo, vaca y perro, respectivamente. Se encontró asociación en la frecuencia de uso de cada vertebrado en Lu. evansi, lo que confirma hábitos antropofílicos y zoofílicos además de su carácter ecléctico.Publicación Acceso abierto Lutzomyia abonneci y Lutzomyia olmeca bicolor (Diptera: Psychodidae), nuevos registros para el departamento de Sucre, Colombia.(Bogotá, Colombia: Acta Biológica Colombiana , 2013., 2019-10-03) Romero Ricardo, Luis; Lastre Meza, Natalia; Pérez Doria, Alveiro; Bejarano Martínez, EduarAmong Colombia’s Caribbean coast departments, Sucre has the greatest species diversity of phlebotomine sand flies (genus Lutzomyia), including several associated with the epidemiological cycles of cutaneous and visceral leishmaniasis. Due to its public health importance, the phlebotomine fauna of Sucre must be monitored periodically. Sand flies were collected in the ecological reserve of the municipality of Colosó, Sucre, during the months of December 2009, 2010 and 2011. Three sampling methods were employed, i.e., daytime collections from diurnal resting sites with a battery-powered aspirator and nocturnal collections using two CDC light traps and a Shannon trap. With these methods 566 phlebotomines were collected belonging to 14 species: Lu.evansi, Lu. panamensis, Lu. micropyga, Lu.gomezi, Lu. cayennensis cayennensis, Lu. trinidadensis, Lu.venezuelensis, Lu. serrana, Lu. abonnenci, Lu. migonei, Lu. dubitans, Lu. olmeca bicolor, Lu. atroclavata and Lu. ovallesi. Shannon trap collections accounted for 48,2 % of all phlebotomines collected, those with CDC light traps 36,6 % and with battery-powered aspirator 15,2 %. Both Lu. abonnenci and Lu. o. bicolor, species with wide spread in Colombia, represent new species records for the department of Sucre.Publicación Acceso abierto Nuevos hallazgos de flebotomíneos (Diptera: Psychodidae) en la Sierra Nevada de Santa Marta, Colombia.(Bogotá, Colombia: Acta Biológica Colombiana , 2015., 2019-10-02) Bejarano, Uribe, Sandra Inés Eduar Elías; Pérez Doria, Agurrola, Jorge Alveiro; Dib, Porter, Charles H. Juan CarlosPhlebotomine 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.Publicación Acceso abierto Nuevos registros de flebotomíneos (Diptera: Psychodidae) en el área de influencia del río Amoyá en Chaparral, Tolima.(Bogotá, Colombia: Revista Biomédica, 2012., 2019-10-04) Contreras, María Angélica; Vivero, Rafael José; Bejarano, Eduar Elías; Carrillo, Lina María; Carrillo, Lina María; Vélez, Ivan DaríoIn Colombia, the diversity of phlebotomine sand flies is high, with 162 recorded species, and which include vectors of Leishmania spp. The objective of this research is to identify the the sand fly species of medically importance in the area of influence from Amoyá River Hydroelectric Project, Colombia.Publicación Acceso abierto Nuevos registros de flebotomíneos (Diptera: Psychodidae), con el hallazgo de Lutzomyia longipalpis (Lutz & Neiva, 1912), en los alrededores de la Ciudad de Sincelejo, Colombia.(São Paulo, Brasil:Biota Neotropica, 2009., 2019-10-11) Vivero, Rafael José; Bejarano, Eduar Elías; Pérez Doria, Alveiro; Flórez, Fernando; Estrada, Luis Gregorio; Torres, Carolina; Muskus, CarlosThis is the first report of Lutzomyia longipalpis (Lutz & Neiva, 1912), L. shannoni (Dyar, 1929), L. micropyga (Mangabeira, 1942) and L. atroclavata (Knab, 1913) in the surroundings of an urban settlement in the Caribbean coast. Phlebotomine sandflies were collected by active search using suction devices and mouth aspirators in trees around the city of Sincelejo, the capital of the department of Sucre. Epidemiological importance derived from this finding is discussed due to the vectorial capacity of L. longipalpis, the natural vector of Leishmania infantum Nicolle, 1908 in America.Publicación Acceso abierto Primer hallazgo de Lutzomyia tihuiliensis (Diptera: Psychodidae) en el valle de Aburrá, Colombia.(Bogotá, Colombia: Revista Biomédica, 2006., 2019-10-24) Bejarano, Eduar Elías; Sierra, Diana; Pérez Doria, Alveiro; Darío Vélez., IvánThree of the seven species that comprise the pia series of the Lutzomyia verrucarum group have been recorded in Colombia, including L. pia, L. limafalcaoae and L. emberai. Objective. The aim of this paper is to report the occurrence of an anthropophilic morphospecies of the pia series in the country.Publicación Acceso abierto Redescripción de la hembra de Lutzomyia vattierae (Diptera: Psychodidae, Phlebotominae) de la serranía de La Macarena, Colombia.(Bogotá, Colombia: Revista Biomédica, 2006., 2019-10-24) Bejarano, Eduar Elías; Duque, Patricia; Vélez, Iván DaríoLutzomyia species of the subgenus Sciopemyia show restricted distribution andare rarely represented in sand fly captures, with the exception of L. sordellii, which is found fromCosta Rica to Argentina. To date, only two of these species. L. sordellii and L. preclara havebeen reported in Colombia. The female of L. vattierae was redescribedand the record of this Sciopemyia speciesestablished for in the Colombian national park, serranía de La Macarena.Publicación Acceso abierto Trece registros nuevos de Lutzomyia (Diptera: Psychodidae) para el departamento de Vichada, Orinoquia Colombiana.(São Paulo, Brasil : Biota Neotropica, 2010., 2019-10-11) Vivero, Rafael José; Bejarano, Eduar Elías; Castro, Mirley; Vélez, Andrés; Pérez, Juan Esteban; Pérez Doria, Alveiro; Vélez, Iván DaríoLutzomyia trinidadensis (Newstead, 1922), L. bettinii Feliciangeli, Ramírez-Pérez & Ramírez, 1988, L. flaviscutellata (Mangabeira, 1942), L. yuilli Young & Porter, 1972, L. saulensis (Floch & Abonnenc, 1944), L. runoides (Fairchild & Hertig, 1953), L. ayrozai (Barretto & Coutinho, 1940), L. claustrei Abonnenc, Leger & Fauran, 1979, L. walkeri (Newstead, 1914), L. preclara Young & Arias, 1984, L. (geniculata) sp., L. (squamiventris) sp., and L. (Evandromyia) sp., are recorded for the first time in the department of Vichada, Colombia. In addition, the presence of L. antunesi (Coutinho, 1939) and L. aragaoi (Costa Lima, 1932) in this department is confirmed. Sand flies were collected in the municipalities of Puerto Carreño, Cumaribo, and La Primavera, using CDC light traps, Shannon trap, and human bait, and by active search in resting places. The epidemiological importance of these sand fly species is discussed in relation with the cutaneous leishmaniasis.
