triatoma jatai sp. nov. in the state of tocantins, brazil (hemiptera: reduviidae: triatominae).triatoma jatai sp. nov. is the first new species of triatomine to be described in the state of tocantins, in the northern region of brazil. it was caught on rock outcrops in the wild environment and, more recently, invading homes. while t. jatai sp. nov. is morphologically similar to triatoma costalimai, it is distinguished by its general colouring, differences in the blotches on the connexivum, wing size in females and external structures of the male genitalia. the type series has been deposite ...201323828010
chromosomal characteristics and distribution of constitutive heterochromatin in the matogrossensis and rubrovaria subcomplexes.since 1966 the triatomines were grouped in complexes and specific subcomplexes. although the complex and subcomplexes not have taxonomic importance, should be monophyletic groups and cytogenetic tools have proved to be of great importance to characterize these species groupings. based on this, this paper aims to describe the chromosomal characteristics and heterochromatic pattern of matogrossensis and rubrovaria subcomplexes, in order to contribute to the taxonomic and evolutionary relationships ...201525917494
occurrence of triatoma costalimai (hemiptera: reduviidae) in different environments and climatic seasons: a field study in the brazilian savanna.trypanosoma cruzi-infected specimens of triatoma costalimai have been detected in domiciliary units of central brazil, thereby maintaining the potential risk of vectorial transmission of chagas disease. the aim of this study was to determine the occurrence and natural infection of t. costalimai in different environments (gallery forest, dry forest and peridomicile) and climatic seasons (wet and dry), in the municipality of mambaí, state of goiás, brazil.201223152338
a study of the scutellum in eight chagas disease vector species from genus triatoma (hemiptera, reduviidae) using optical and scanning electron microscopy.the aim of this study was to analyze the external morphology of the scutellum through optical microscopy and scanning electron microscopy (sem) in male specimens of triatoma costalimai, t. delpontei, t. eratyrusiformis, t. matogrossensis, t. infestans melanosoma, t. sherlocki, t. tibiamaculata, and t. vandae. a total of 30 photographs of the scutellum were made. magnification varied from 50x to 750x. regarding depth and forms of the central depression, the heart-shaped form was predominant, with ...200717612766
[geographical distribution and indicators entomologic of sinantropic triatomines captured in the state of goiás].the geographic distribution of triatomines in goiás and entomological indicators in the home environment are presented: home infestation, home triatomine density and vector infection by trypanosoma cruzi. the indicators studied were from triatomines captured inside and outside homes in 201 municipalities in the state of goiás, brazil, between 2000 and 2003. a total of 249,868 home units were investigated and 51,570 triatomines were captured, and 335 specimens were found to be infected with trypa ...200717568889
mitochondrial genes reveal triatoma jatai as a sister species to triatoma costalimai (reduviidae: triatominae).triatoma jatai was described using a set of morphological structures from specimens collected in paranã municipality of tocantins state, brazil. under a bayesian framework and using two mitochondrial genes (16s and coi), phylogenetic analysis recovered t. jatai as a sister species to triatoma costalimai with higher genetic distances than between other well-recognized species. our results agree with previous suggestions based on morphometric analysis. in the light of the non-monophyly of matogros ...201626787157
triatoma costalimai (hemiptera: reduviidae) in and around houses of tocantins state, brazil, 2005-2014.triatoma costalimai verano & galvão, a little-known vector of trypanosoma cruzi chagas, occupies rocky environments in the brazilian cerrado and occasionally infests man-made habitats. entomological surveillance records show that t. costalimai occurs fairly often inside and around houses in south-eastern tocantins, brazil, with 859 specimens reported in 2005-2014. most adults were caught indoors, and breeding colonies were found inside and around houses. trypanosoma cruzi was detected in 13.7% o ...201729106640
