RESUMO
La fauna flebotomínea del Caribe colombiano es aún poco conocida, por lo que se hace necesario llevar a cabo estudios para determinar la riqueza de especies de la región. Con este propósito se desarrollaron muestreos entomológicos en enero y marzo de 2007, en el municipio de Colosó, departamento de Sucre, con dos trampas CDC modificadas. En el material recolectado se identificaron dos machos de Brumptomyia hamata, que constituyen el primer registro de este flebotomíneo para el Caribe colombiano. Las características morfológicas observadas en los ejemplares de B. hamata son consistentes con la descripción original de la especie, excepto por las espinas del estilo que se distribuyen en tres grupos. Se plantea que tales diferencias pueden corresponder a variaciones intraespecíficas entre poblaciones geográficas.
The sand fly fauna of the Colombian Caribbean is still not completely known and further surveys are needed in order to determine the richness of species over the region. Entomological samplings were performed in the municipality of Colosó , department of Sucre , using two modified CDC traps, in January and March of 2007. Two males belonging to Brumptomyia hamata were identified. It is the first record of this sand fly species from the Colombian Caribbean. With the exception of the distribution of spines on the style in three distinct groups, all other morphological characters of the individuals of B. hamata agree with the original description of the species. The observed difference could be attributed to intraspecific variation among geographic populations.
RESUMO
Se registra por primera vez para el Departamento de Guainía, Colombia, la presencia del género Lutzomyia França de reconocida importancia médica. Los flebotomíneos se recolectaron mientras intentaban picar al humano en los alrededores del casco urbano del municipio de Inírida. Se identificaron taxonómicamente tres especies de Lutzomyia, incluidas L. davisi (Root), L. olmeca bicolor Fairchild & Theodor, y L. antunesi (Coutinho). Adicionalmente, Brumptomyia mesai Sherlock es citada por primera vez en el litoral Caribe Colombiano a partir de ejemplares colectados con una trampa de luz CDC modificada en la Reserva Forestal Protectora Serranía de Coraza y Montes de María, Departamento de Sucre.
This is the first record of the presence of the medically important genus Lutzomyia França in the Department of Guainía, Colombia. Sand flies were collected biting humans in the surroundings of the urban area of the Municipality of Inírida. Three Lutzomyia species were taxonomically identified as L. davisi (Root), L. olmeca bicolor Fairchild & Theodor, and L. antunesi (Coutinho). Additionally, Brumptomyia mesai Sherlock is cited for the first time in the Caribbean Coast of Colombia based on specimens collected with a modified CDC light trap in the Reserva Forestal Protectora Serranía de Coraza y Montes de María, Department of Sucre.
