| misidentification of two brazilian triatomes, triatoma arthurneivai and triatoma wygodzinskyi, revealed by geometric morphometrics. | triatoma arthurneivai lent & martins and triatoma wygodzinskyi lent (hemiptera: reduviidae) are two brazilian species found in the sylvatic environment. several authors may have misidentified t. arthurneivai and consequently published erroneous information. this work reports the use of geometric morphometric analysis on wings in order to differentiate t. arthurneivai and t. wygodzinskyi, and thus to detect possible misidentifications. triatomines collected from the field in the states of minas g ... | 2010 | 21039685 |
| the association between the geographic distribution of triatoma pseudomaculata and triatoma wygodzinskyi (hemiptera: reduviidae) with environmental variables recorded by remote sensors. | in this study, predictive models of geographic distribution patterns of triatoma pseudomaculata (tps) and t. wygodzinskyi (twy) were carried out. they were based on biophysical variables estimated from information provided by the satellite remote sensors avhrr (advanced very high resolution radiometer) and modis (moderate-resolution imaging spectroradiometer). our goal was to analyze the potential geographic distribution of tps and twy and to assess the performance of three predictive models (on ... | 2009 | 18992369 |
| differentiation between triatoma arthurneivai and triatoma wygodzinskyi (hemiptera: reduviidae: triatominae) using cytotaxonomy. | using classic morphometric techniques to examine the head and thorax of triatoma specimens, researchers identified a possible taxonomic problem involving t. arthurneivai (lent & martins) and t. wygodzinskyi (lent). a recent geometric morphometric study indicated that the insects captured outside the serra do cipó region, state of minas gerais, brazil, were t. wygodzinskyi. the misidentification of t. arthurneivai as t. wygodzinskyi could result in several problems associated with entoepidemiolog ... | 2016 | 27420940 |
| inferences about antennal phenotype: the "triatoma maculata complex" (hemiptera: triatominae) is valid? | the "triatoma maculata complex" is presently formed by two epidemiologically important species of triatominae, triatoma maculata and triatoma pseudomaculata, which share morphologic and chromatic characteristics. in order to clarify the systematic status and infer the evolutionary relationships of these vectors of chagas disease, we performed a comparative analysis of their antennal phenotype, taking also into account triatoma wygodzinskyi, a possible sister species. the comparison was based on ... | 2008 | 18282553 |
