| dc.description | An ecological-evolutionary classification of Amazonian triatomines is proposed based on a revision of
their main contemporary biogeographical patterns. Truly Amazonian triatomines include the Rhodniini, the
Cavernicolini, and perhaps Eratyrus and some Bolboderini. The tribe Rhodniini comprises two major lineages
(pictipes and robustus). The former gave rise to trans-Andean (pallescens) and Amazonian (pictipes) species
groups, while the latter diversified within Amazonia (robustus group) and radiated to neighbouring ecoregions
(Orinoco, Cerrado-Caatinga-Chaco, and Atlantic Forest). Three widely distributed Panstrongylus species probably
occupied Amazonia secondarily, while a few Triatoma species include Amazonian populations that occur
only in the fringes of the region. T. maculata probably represents a vicariant subset isolated from its parental
lineage in the Caatinga-Cerrado system when moist forests closed a dry trans-Amazonian corridor. These
diverse Amazonian triatomines display different degrees of synanthropism, defining a behavioural gradient
from household invasion by adult triatomines to the stable colonisation of artificial structures. Anthropogenic
ecological disturbance (driven by deforestation) is probably crucial in the onset of the process, but the fact that
only a small fraction of species effectively colonises artificial environments suggests a role for evolution at the
end of the gradient. Domestic infestation foci are restricted to drier subregions within Amazonia; thus, populations
adapted to extremely humid rainforest microclimates may have limited chances of successfully colonising
the slightly drier artificial microenvironments. These observations suggest several research avenues, from the use of climate data to map risk areas to the assessment of the synanthropic potential of individual vector species. | |
