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

A new species of Planthopper, Nogodina chiapaneca sp. nov. from the Mexican Chiapas amber (southeast Mexico) is described. The new species belongs to Nogodinidae: Nogodinini: Nogodinina. This is the second nogodinid species described from Mexican amber. Both species belong to Nogodinina, a taxon with a Neotropical distribution. The only recent species of Nogodina, N. reticulata, ranges from Honduras to Brazil and is unknown from Mexico yet. 相似文献

In Chiapas, southern Mexico, there are Miocene amber deposits containing high diversity of biological inclusions of plants, fungi, crustaceans, and vertebrates. Here I describe a new species of Podopterus (Polygonaceae), P. mijangosae n. sp. based on well-preserved fruit fossils collected from the Los Pocitos mine, Chiapas. The fruit specimens are characterized by obovate shape, emarginate apex, cuneate base with three thin wings, and the endocarp being pubescent or tomentose. The wings are thin and translucent with entire to undulate margin, pubescent hairs, and fine fusiform-reticulate venation. This new record of Podopterus represents the second fossil record to the southernmost in North America, and further supports the idea that several genera that grow in Mexico today were present in the area since the Miocene. 相似文献

Phlebotominae sand fly specimens were prepared for histological and physiological studies. Different fixatives were tested on sectioned and whole bodied adult females in order to obtain good fixation and provide satisfactory penetration of the embedding media. All fixed specimens were infiltrated (up to seven days under 5 C) and embedded in hydroxyethyl metacrylate. Two-three m sections were stained, mounted in Canada balsam and observed by light microscopy. Best results were achieved when whole bodied insects were double fixed in Bouin's and Carnoy's fluids (4 h/2 h) and stained in Hematoxilin/Eosin or fixed in calcium formaldehyde and stained in mercury bromophenol blue. 相似文献

Monitoring phlebotomine sandflies in urban areas is key for epidemiological studies
in susceptible populations. This paper describes sandfly fauna that were present in
an urban area of the municipality of Tapachula, Chiapas, Mexico, and were captured
with Shannon and CDC light traps. During February and March of 2014, 1,442 sandflies
were captured, specifically Lutzomyia cruciata (Coquillet) (98.8%), Lutzomyia
cayennensis cayennensis (Floch and Abonnenc) (0.8%), Lutzomyia chiapanensis (Dampf)
(0.3%) and Lutzomyia atulapai (De León) (0.1%). Lu. cruciata was the most abundant
and the most frequently trapped species. This is the first record of its remarkable
ability to adapt to urban green areas. The three other species trapped represent new
records of geographic distribution for the study region. These results indicate the
need to establish measures for reducing both human contact with this vector and the
risk of possible sites of infection. 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

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

The fossil record of the Tabanidae is sparse when compared with other families of Diptera. Even in amber they are rare, probably because of their size and specific flight behavior. Horseflies from amber are only known from Cretaceous age New Jersey amber as well as from the Tertiary age Baltic and Dominican amber, but are herein described for the first time, with Stenotabanus oleariorum sp. n., from Mexican amber. The new species is compared to the fossil horseflies of the same genus S. brodzinskyi Lane, Poinar and Fairchild 1988 and S. woodruffi Lane and Fairchild 1989 from Dominican amber. 相似文献

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

Ceratozamia norstogii sp. nov. from Chiapas, Mexico is described. This species is distinct from all others in the genus in that it has a straight rachis with very narrow leaflets (3–10 mm wide) which are strongly curved and almost round in cross section when dried. It is known only from Chiapas, Mexico and in cultivation. 相似文献

Govenia rubellilabia, a new terrestrial orchid from Sierra Madre de Chiapas, Mexico, is described and illustrated. Diagnostic characters of this
new species are compared with other species ofGovenia. Govenia rubellilabia is similar in appearance toG. matudae, but it can be distinguished from this species by a shorter inflorescence with fewer flowers, green-yellowish tepals, a reddish
lip lacking spots in the margin of the apex, and by a shorter anther beak. 相似文献

A new species of parthenogenetic, autogenic and apparently extremely endemic phlebotomine is described from a sandstone cave located in primary terra firme forest to the North of the city of Manaus. Specimens were collected in the aphotic zone of the Refúgio do Maruaga cave by light trap and reared from bat guano. The adult morphology suggests a closer relationship to some Old World Phlebotominae than to species of Lutzomyia Fran?a encountered in the surrounding rainforest, but it shares characteristics with the recently proposed Neotropical genera Edentomyia Galati, Deanemyia Galati and Oligodontomyia Galati. 相似文献

Several species of the subgenus Psychodopygus Mangabeira, 1941 are known to be leishmaniosis vectors in Brazil. Some of them are morphologically similar, which makes their identification quite difficult concerning epidemiological studies. The aim of the current work is to study the morphology of adult specimens of the subgenus Psychodopygus, in accordance with the morphological similarity and still taking into account the epidemiological importance of some species. Thus 11 species have been studied, including four subspecies of adult specimens deposited in the phlebotomine collection of Centro de Pesquisas René Rachou-Fiocruz. Morphological characters found in the literature and new features observed in this study were recorded in a taxonomic discussion format. These characters make it easy to separate such species. Four taxa, previously considered as subspecies, were raised to the category of species. 相似文献
