Abstract | The Triatoma sordida subcomplex traditionally included four triatomine species, T. sordida, Triatoma
garciabesi, Triatoma guasayana, and Triatoma patagonica, distributed in the Southern Cone of South America.
These species have a large intraspecific variability together with an overall similarity, making difficult to establish
their taxonomic status. Many cytogenetic, morphometric, and molecular markers have been applied
to address this. Recent studies have posed concerns on the inclusion of T. guasayana and T. patagonica within
the subcomplex. Also, T. sordida from Argentina has been designed as a new species, Triatoma rosai. Using
the cuticular hydrocarbon pattern as chemotaxonomic marker, the relationships among several populations
of these species were analyzed by capillary gas chromatography and linear discriminant analysis along 25
collection sites in Argentina, Bolivia, Brazil, and Paraguay. T. sordida and T. rosai populations were differentially
clustered in two CHC-based groups: “Group 1” included T. sordida from Eastern Brazil, Eastern Paraguay,
and the Bolivian populations from La Paz and Izozog G1; “Group 2” included T. rosai, and T. sordida from
Izozog G2 (Bolivia), and Western Paraguay. Whereas T. garciabesi remained closely related to T. sordida and
T. rosai, T. guasayana, and T. patagonica were clearly separated from the species of the T. sordida subcomplex.
Our results agree with those from other several techniques suggesting that the taxonomy of the T. sordida
subcomplex should be revised. | pt_BR |
