Distribuição Geográfica e Dispersão Alti-latitudinal de Alguns Gêneros e Espécies da Tribo Triatomini Jeannel, 1919 (Hemiptera, Reduviidae, Triatominae)

Geographical Distribution and Alti-latitudinal Dispersion of Some Genera and Species of the Tribe Triatomini Jeannel, 1919 (Hemiptera, Reduviidae, Triatominae) - With the currently known distribution of genera and species of the tribe Triatomini Jeannel, 1919, maps and diagrams were prepared, showing the geographical area occupied by the species and their respective dispersion in grades of latitude and altitude. Two genera are not treated: Panstrongylus Berg, 1879, already published and Triatoma Laporte, 1832, that is being published partially in several articles. Genus Eratyrus Stal, 1859, has two species, while Dipetalogaster Usinger, 1939, Mepraia Mazza, Gajardo & Joerg, 1940, Paratriatoma Barber, 1938 and recently created genus Hermanlentia Jurberg & Galvão, 1997, have only one each. The study of these maps and diagrams permits a better knowledge about some ecological requirements of Chagas' disease vectors and detects gaps in the geographical distribution, where the species were not found but probably they could be prevalent

Triatoma jurbergi sp. n. do Norte do Estado do Mato Grosso, Brasil (Hemiptera, Reduviidae, Triatominae) com uma Atualização das Sinonímias e outros Táxons

Triatoma jurbergi n. sp. is described based on nine specimens of both sexes deposited in the Rodolfo Carcavallo Collection in the Oswaldo Cruz Institute Entomological Collection. The new species can be separated from the closely related Triatoma guazu Lent & Wygodzinsky, 1979 by several characters. The most important are longer anteocular region; thin and pointed juga; the shape of the eyes without concavity in the posterior edge; much longer second rostral segment, passing the posterior edge of eye; the absence of a ventral longitudinal depression on the abdomen; the general color redish, brown and orange and the male genitalia, mainly in the vesica lightly chitinized and smaller, the phallosome with apical projection and the pointed apex of the endosome process.

Presence of Panstrongylus rufotuberculatus (Champion, 1899) (Hemiptera: Reduviidae: Triatominae) in Argentina

Panstrongylus rufotuberculatus is reported for the first time in Argentina. Four adults were attracted by the light of human dwellings in Calilegua National Park, Jujuy, at 1150 masl within the subtropical humid forest. The individuals were similar to those described in the literature. The epidemiological significance of this species is very low in the area, although deforestation might increase its role in the transmission of Trypanosoma cruzi.

Triatoma bassolsae sp. n. from Mexico with a key to species of "phyllosoma" complex

According to the descriptions of five closely related species of the genus Triatoma Laporte, 1832: T. phyllosoma (Burmeister, 1835), T. pallidipennis (Stal, 1872), T. picturata Usinger, 1939, T. longipennis Usinger, 1939 and T. mazzottii Usinger, 1941 and further published studies, these species could be included in a "specific complex" named as the species formerly described. All these species are typical from Mexico and another species was found in the same country, in the State of Puebla: Triatoma bassolsae sp. n. This species was morphologically compared with the other five of the "phyllosoma" complex, including the external male genitalia. The most important characters used to separate T. bassolsae from T. phyllosoma (which is the most similar to the other species) are the morphometric relationships on the head, with a longer anteocular region and a significant longer second rostral segment, a long and conspicuous pilosity in different areas of the body and specially on the head, and the characters of the anterolateral, lateral and discal tubercles of the pronotum, very long and sharp in the new species. The male genitalia has several differences between T. bassolsae and T. phyllosoma specially significant on the surface of the endosome process and on the branches of the phallosome support, separated at the apex in the new species. Types and paratypes are incorporated in the respective institutions in Mexico DF and Rio de Janeiro.

Nova espécie do complexo oliveirai (nova denominação para o complexo matogrossensis) (Hemiptera, Reduviidae, Triatominae) do estado do Rio Grande do Sul, Brasil

The authors describe a new species of Triatominae (Hemiptera, Reduviidae) from the State of Rio Grande do Sul, Brazil. The study was made with specimens captured in basaltic formations, at an average altitude of 750 m.o.s.l. The new species is included in the oliveirai complex together with other four species T. williami, T. matogrossensis, T. guazu and T. jurbergi). The new species was compared with the most similar one, T. oliveirai, from which the main differences are on the proportions of head, ante and postocular regions, the general color pattern and the male genitalia, specially on the median process of the pygophore, the support of phallosome, the vesica and the process of the endosome.

Início da atividade de vôo em Triatoma infestans (Klug, 1834) e T. melanosoma Martínez, Olmedo & Carcavallo, 1987 (Hemiptera, Reduviidae)

The flight initiation of T. infestans, the main vector of Chagas disease in the Southern Cone countries of Latin America, and of the closely-related species T. melanosoma was studied in laboratory. The results demonstrated that after the beginning of observations the peak of the flight activity was about 14 days after feeding in both species and it was usually more marked in the females than in the males, but there were no significant differences in the flight behaviour of the two species.

Descrição dos Ovos e dos Estádios Ninfais de Triatoma jurbergi Carcavallo, Galvão & Lent, 1998 Vistos Através de Microscopia Óptica e Eletrônica de Varredura (Hemiptera, Reduviidae)

Eggs and nymphs of Triatoma jurbergi were described using optical microscopy and scanning electron microscopy. T. jurbergi is a wild species, found in State of Mato Grosso (15ºS and 300 m.a.s.l), Brazil. Eggs showed the operculum and surface with pentagonal and hexagonal cells, with small fractures and punctuations randomly distributed. Differences were found in the five nymphal stages of T. jurbergi, that allow their to be distinguished from the similar species T. guazu. The diagnostic characters most useful for differentiation were the general color of the insect, abdomen shape and its length.

Triatoma vandae sp. n. do complexo oliveirai encontrada no estado de Mato Grosso, Brasil (Hemiptera: Reduviidae: Triatominae)

There are several specific complexes belonging to the genus Triatoma Laporte, 1832, which are generally associated to specific geographic areas. Recent publications have linked the oliveirai complex to ecosystems of Mato Grosso, which are also present in other Brazilian states and even in other bordering countries as eastern Paraguay. The study of the abundant material collected during the last years allowed the description of several new species of the oliveirai complex: T. jurbergi Carcavallo, Galvão & Lent, 1998; T. baratai Carcavallo & Jurberg, 2000 and T. klugi Carcavallo, Jurberg, Lent & Galvão, 2001. Another new species belonging to the same complex is described here as T. vandae sp.n. It originates from the state of Mato Grosso, and has been reared in the insectary of the Laboratório Nacional e Internacional de Referência em Taxonomia de Triatomíneos, Departamento de Entomologia, Instituto Oswaldo Cruz-Fiocruz, Rio de Janeiro.

Should Trypanosoma cruzi be called "cruzi" complex? A review of the parasite diversity and the potential of selecting population after in Vitro culturing and mice infection

Morpho-biological diversity of Trypanosoma cruzi has been known since Chagas' first works in 1909. Several further studies confirmed the morphological differences among the parasite strains, which were isolated from different reservoirs and vectors, as well as from human beings. In the early sixties, antigenic differences were found in the parasite strains from various sources. These differences, coupled to the observation of regional variations of the disease, led to the proposal of the term cruzi complex to designate the taxon T. cruzi. Since then this protozoan has been typed in distinct biodemes, zymodemes and lineages which were consensually grouped into T. cruzi I, T. cruzi II and into non-grouped strains. T. cruzi genotypic characterization, initially carried out by schizodeme analysis and more recently by various other techniques, has shown a great diversity of the parasite strains. In fact, T. cruzi is formed by groups of heterogeneous sub-population, which present specific characteristics, including distinct histotropism. The interaction of the different infecting clones of the cruzi complex and the human host will determine the morbidity of the disease.

Comparative study of the stridulatory sulcus, buccula and rostrum of the nymphs of Triatoma guazu Lent & Wygodzinsky, 1979 and Triatoma jurbergi Carcavallo, Galvão & Lent, 1998 by scanning electron microscopy (Hemiptera, Reduviidae)

The ultrastructural morphology of the ventral region of the head (rostrum and buccula) and proesternum (stridulatory sulcus) of nymphs from the 1st to 5th instars of Triatoma guazu Lent & Wygodzinsky, 1979 and Triatoma jurbergi Carcavallo, Galvão & Lent, 1998 was described. Morphological differences between the two species and of the five nymphal stages development of each species were observed. These structures showed systematic differential characteristics of the studied species and may be used to increase their taxonomic range.

Morfologia comparada dos ovos e ninfas de Triatoma vandae Carcavallo, Jurberg, Rocha, Galvão, Noireau & Lent, 2002 e Triatoma williami Galvão, Souza & Lima, 1965 (Hemiptera, Reduviidae, Triatominae)

Eggs and all nymphs of these species were studied employing light microscopy (LM) and scanning electron microscopy (SEM). The major differences observed by LM in the eggs were related to the presence and the distribution of pores on the surface of their chorion. Morphological differences among three nymphal stages (1st, 3rd, and 5th) development of each species were observed. The differential characteristics are chromatic and in the shape of connexival spots. The ultrastructure of the ventral region of the head and the IX, X, and XI abdominal segments (anal tube) of the both species were described demonstrating morphological differences that can be used for diagnosis of the species.
