A sand fly fossil was found in amber; a vegetal resin, which allows all the external phlebotomine structures to be seen. The piece that contains the new species is 14 mm long x 8 mm wide x 3 mm high. All the structures from the head, thorax, and abdomen were examined under the microscope and measured with a calibrated micrometric eyepiece. The morphological aspects of the new species suggest its inclusion in the Pintomyia genus, Pifanomyia subgenus though it is not possible to include it in any of the series known for this subgenus. The presence of two atrophied spines on the gonostyles and gonocoxites without tufts of setae permit the exclusion of the new species from the other species of the subgenus Pifanomyia. The new species is named Pintomyia (Pifanomyia) brazilorum sp. nov. 相似文献

A new species of sand fly, Pintomyia (Pifanomyia) falcaorum is described from an amber originated from the northern mountain range of Dominican Republic. The male sand fly specimen is well preserved and most features used in Phlebotominae taxonomy are seen with remarkable clarity. 相似文献

The present paper describes a new phlebotomine species, Evandromyia gaucha sp. nov., based on seven females found in the municipality of Ca?apava do Sul, state of Rio Grande do Sul, Brazil. The new species belong to rupicola series and differs from other sand flies of the genus Evandromyia due to the presence of a rounded spermatheca head with its size very close to that of the spermatheca body. 相似文献

A new fossil species of phlebotomine sandflies is described from Dominican amber based in one specimen. Pintomyia (Pifanomyia) paleotrichia sp. nov. is distinguished from the other extant and extinct species by aspects of paramere and the basal tuft of bristles in the gonocoxite. 相似文献

During a study of the phlebotomines of the Brazilian state of Tocantins, a new species was discovered in Porto Nacional county, here described as Micropygomyia (Silvamyia) echinatopharynx sp. nov. This is only the second species of the subgenus Micropygomyia (Silvamyia) to be described. 相似文献

Both sexes of Sergentomyia (Parrotomyia) rectangulata sp. nov. from southern India are described with illustrations. The specimens were collected in tree holes, termite mounds, cattle sheds and mud-walled, thatched roof human dwellings in rural areas. Our findings reveal similarity with Sergentomyia (Parrotomyia) modii Lewis. 相似文献

A species of the Lutzomyia oswaldoi group is recorded from the Valcheta stream basin, Somuncura plateau, Patagonia. It represents the World southermost record of a species of Phlebotominae, apparently supporting the hypothesis about the relictual character of several components of the Somuncura plateau biota, particularly for those species belonging to the Paranaense lineages. 相似文献

Heydenius dominicus n. sp. is described as a new species of fossil mermithid nematode from Dominican Republic amber. The species is represented by two specimens of parasitic juveniles that left their insect host and became embedded in the resin. The nematodes are associated with an adult male limoniid (Diptera: Limoniidae) and an adult female mosquito (Diptera: Culicidae). The parasites are thought to have emerged from the mosquito host. This is the first report of a fossil mermithid from a Neotropical area. 相似文献

17 males and 7 females of Sergentomyia (Parrotomyia) gobica sp. n. were collected in Tsubulur-Khara-Nuru mountains (Bayan-Khongor region) of the Mongolian People's Republic in August of 1980 and in July of 1982. The new species is similar to S. (Parr.) sumbarica (Perfiliew), 1933. 相似文献

The fossil record and systematics of phlebotomid sand flies, vectors of leishmaniasis and arbovirus in several regions of the world, strongly support that living genera existed long before the Oligocene (38 million years, myr). A common Phlebotominae ancestor was present in the Triassic period before the separations of continents (248 myr). 相似文献

The bionomics of sand flies (Diptera: Phlebotominae) was studied monthly for two consecutive years in alluvial gallery forests in the department of Casanare, Northeastern Colombia. A total of 2,365 specimens and 10 species were captured using CDC light traps and Shannon traps, and from diurnal resting places, and human landing collections. Lutzomyia fairtigi Martins (55%), Lutzomyia micropyga (Mangabeira) (20.9%), and Lutzomyia antunesi (Coutinho) (13.5%) were the predominant species in the region. Lutzomyia flaviscutellata and Lutzomyia panamensis, potential vectors of Leishmania in Colombia and neighboring countries, were also collected, but in low numbers. Lu. fairtigi is an endemic species to Colombia, and minimal data are available on its biology and distribution. The present study provides additional information about Lu. fairtigi, such as the diurnal activity displayed by females on cloudy days, the greater density during the rainy season (April to October), marked anthropophilia, and the presence of flagellates in the midgut of one female. 相似文献

Among the phlebotomine sandflies collected in a lime-stone cave of 21 degrees 42' N, 10 degrees 23' E and 700 m above sea level on 14th August, Mengyuan, Mengla County, Xishuangbanna District, Yunnan Province, two males of the group fallax of subgenus Sergentomyia are quite different in morphology with those hitherto recorded in the literature. In the present paper its morphology is described with seven figures and the name Sergentomyia wangi is proposed in honor of professor Chao-Tsun Wang for his contribution in study and control of leishmaniasis in China. 相似文献

The male of Pintomyia (Pifanomyia) bolontikui sp. nov., from the Miocene Mexican amber deposits of Simojovel, Chiapas, is described. This is the second fossil phlebotomine sand fly described from Mexico. Morphological differences between fossil and extant species of American phlebotomine sand flies are discussed. 相似文献

During studies of the phlebotomine sand fly fauna of Campo Grande, State of Mato Grosso do Sul, Brazil, a new species was captured with CDC light trap and is described here. The new species resembles Lutzomyia lutziana (Costa Lima) and is named Lutzomyia campograndensis sp. n. after the type locality. 相似文献
