Morphological description of Pintomyia (Pifanomyia) veintemillasi n. sp., a new sand fly species from the sub-Andean region of Bolivia.

Background: Most sand fly species are located in the Americas; some act as vectors of leishmaniasis and other human diseases. In Bolivia, about 25% of Neotropical species have been identified, and only a few have been implicated as vectors of cutaneous and visceral leishmaniasis. A new species of anthropophilic sand fly from the sub-Andean region of Alto Beni is described herein.

Two new species of Bruchomyiinae (Diptera, Psychodidae) from the Neotropical Region.

Males of two Bruchomyiinae species were collected during fieldwork in Central and South America. Boreofairchildia belti Ježek, Oboňa Le Pont sp. nov.

PCR-RFLP of ribosomal internal transcribed spacers highlights inter and intra-species variation among Leishmania strains native to La Paz, Bolivia.

Human leishmaniasis is highly endemic in Bolivia and shows a growing incidence. This report reveals the genetic variability of 35 isolates mainly belonging to Leishmania braziliensis and Leishmania amazonensis species. Among them, 31 were from human patients with different clinical presentations, 3 strains from Lutzomya nuneztovari anglesi (the proven vector of L.

Geographic variation of metric properties within the neotropical sandflies.

Traditional morphometrics remains a useful tool for differentiating sandflies species, particularly closely related taxa. Within a single species, however, size variation among geographic populations might interfere with species distinction. In the past decades, a search for a metric property less prone to individual variations led to the use of ratios, and more recently to the use of size-free variables (after tentative size extraction).
