Description of a new species, Pintomyia dissimilis nov. sp., a phlebotomine fossil from Dominican Republic amber (Diptera: Psychodidae: Phlebotominae)

<p>Abstract</p> <p>Background</p> <p>Phlebotomine sandflies are the vectors of etiological agents of leishmaniases in several areas of the world. In the Neotropical Region, the biodiversity of these insects is more than other regions, probably due the long evolutionary period of this group. Miocene amber from Dominican Republic, currently, has a record of 14 extinct species of Phlebotomine sandflies.</p> <p>Results</p> <p>This paper describes a new fossil species of phlebotomine sandfly from amber found in Dominican Republic. This new species is based on morphological characters of a male such as 5° palpomere longer than 3° + 4°, three well-developed spines in the gonostyle, lateral lobe longer than gonocoxite and permit inclusion of the new species in the genus <it>Pintomyia</it>, series <it>serrana</it>. The paramere, with a curvature in the ventral margin, of the middle of the structure, separates the new species from the others fossils or extant species.</p> <p>Conclusion</p> <p>The new species described in the present study named <it>Pintomyia dissimilis </it>nov. sp. is well differenciated from all known species in this genus.</p

Fundação Oswaldo Cruz. Instituto René Rachou. Belo Horizonte, MG, Brasil.Background: The genus Evandromyia is widely found in Brazil, but occurs mainly in Brazilian savannah. To date 13 species have been described in the subgenus Aldamyia. Here we described a new species of Evandromyia (Aldamyia) collected in the State of Mato Grosso do Sul, Brazil. Methods: Measurements were made using a micrometer eyepiece on an Olympus CH-2 binocular microscope and drawings were executed with the aid of a camera lucida. Results: The new species, Evandromyia orcyi sp. nov., is closely related to Evandromyia lenti, Evandromyia carmelinoi and Evandromyia evandroi, however, characteristics of the male terminalia and female spermathecae distinguish it from other species of the genus Evandromyia. Conclusion: With the description of Evandromyia orcyi sp. nov., six species of the subgenus Aldamyia have been reported from the State of Mato Grosso do Sul

Sandflies (Diptera: Psychodidae: Phlebotominae) collected on the banks of the Velhas River in the state of Minas Gerais, Brazil

Leishmaniases are endemic to several Brazilian states, including Minas Gerais. As many cases of these diseases are diagnosed in Minas Gerais every year, this paper aimed to determine the diversity of the species of sandflies vector of leishmaniases, in Lassance and Corinto on the banks of the Velhas River. Over two years, 21,014 specimens of sandflies, belonging to 19 species were captured with light traps. Of these specimens, Nyssomyia neivai (Pinto 1926) (84.18%), Nyssomyia intermedia (Lutz &amp; Neiva 1912) (13.41%), Evandromyia lenti(Mangabeira 1938) (0.99%) and Evandromyia sallesi (Galvão &amp; Coutinho 1939) (0.48%) were the most represented. The former two species could be involved in the epidemiological chain of leishmaniasis in this region. No significant difference was found between the species compositions on the two river banks

Departamento de Fisiologia e Bioquímica de Insetos. Rio de Janeiro, RJ, BrazilSandflies are holometabolous insects that are of great epidemiological importance in the neotropical region as vectors of leishmaniases. Caves are ecotopes that significantly differ from external environments and, among the insects that live or visit their internal area and adjacent environment, sandflies are commonly found. Based on this context, the objective of this work was to examine the period of activity of sandflies in the cave environment in the aphotic zone. Thus, four sandfly captures were conducted, one in each season of the year, in a cave where studies on the bioecological aspects of sandfly fauna have been conducted since 2008. In this same study, we have also noticed the presence of flagellates in some captured females. Catches were carried out for 24 hours using a Shannon trap, light bait, and cave walls were actively searched. We collected a total of 638 sandflies, representing 11 species. The most abundant species and with more intense period of activity were, in descending order: Lu. cavernicola (62%), Ev. spelunca (16%) and Ev. sallesi (14%). A total of 69 females were dissected to check for natural infection, and in five specimens we found living flagellated forms: two Ev. spelunca, two Ev. sallesi and one Sc. sordellii. This study shows that the activity of some species caught in the aphotic zone of the cave, especially Lu. cavernicola, differs from what has already been reported in previous sandfly captures, which are almost always conducted at night and during twilight. The existence of sandflies that were naturally infected with flagellates and the lack of awareness regarding the behaviour of sandflies in cave environments are strong indicators of the need for further study on this group of insects in this ecotope, as a safety measure to protect the visitors of such environment

Species or group of species captured monthly between June 2008 and May 2010 in both environments (inside the cave and outside of the cave) with significant differences in the numbers of the specimens.
