Trece registros nuevos de Lutzomyia (Diptera: Psychodidae) para el departamento de Vichada, Orinoquia Colombiana

Se informa el primer hallazgo de Lutzomyia 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., y L. (Evandromyia) sp., en el departamento de Vichada, Colombia. También se confirma la presencia de L. antunesi (Coutinho, 1939) y L. aragaoi (Costa Lima, 1932) en este departamento. Los flebotomíneos fueron recolectados en los municipios de Puerto Carreño, Cumaribo, y La Primavera, con trampas de luz tipo CDC, trampa Shannon y atrayente humano, y mediante búsqueda activa en lugares de reposo. Se discute la importancia epidemiológica de estas especies de flebotomíneos en relación con la leishmaniosis cutánea.

Two new species of Ananteris (Scorpiones, Buthidae) from El Tuparro Natural National Park, eastern Colombia

Two new scorpion species, Ananteris faguasi sp. nov. and Ananteris volschenki sp. nov., are described from the eastern extreme of El Tuparro Natural National Park, eastern Colombia near the border with Venezuela. These new species are the first of the genus to be known from Vichada department, and represent the easternmost records in the country. With their description, the number of known species of Ananteris is raised to 64, ten of which are present in Colombia. A map with the known distribution of the Colombian species of Ananteris is presented. To cite this article: R. Botero-Trujillo, C. R. Biologies 332 (2009).

A NEWLY RECOGNIZED SPECIES IN THE ANOPHELES (NYSSORHYNCHUS) ALBITARSIS COMPLEX (DIPTERA: CULICIDAE) FROM PUERTO CARREÑO, COLOMBIA

We report a previously unrecognized mosquito species from eastern Colombia belonging to the Anopheles (Nyssorhynchus) albitarsis complex. We provisionally name this taxon An. albitarsis species "F." Until now, the only members of the Albitarsis Complex recorded from north of the Amazon River have been An. marajoara and a putative phylogenetic species, An. albitarsis "E." As with the other largely monomorphic species in the complex, we were able to detect its presence using ribosomal DNA internal transcribed spacer 2 (rDNA ITS2) and partial white gene sequences. Unlike An. marajoara, but in common with other species in the complex, An. albitarsis F lacks the white gene fourth intron. This species is sympatric with An. marajoara in a malaria-endemic area in Puerto Carreño, Vichada Department, Colombia. It could be an important current and/or historical vector of human malaria parasites at this locality and, depending on its actual distribution, elsewhere in Colombia and Venezuela.
