Panstrongylus megistus

provided by wikipedia EN

Panstrongylus megistus is a blood-drinking insect in the subfamily Triatominae. It is found in the Guianas,[1] Brazil, Bolivia, Paraguay, Uruguay and Argentina,[2] and is an important vector of Trypanosoma cruzi (the causative agent of Chagas disease),[3] particularly in Brazil.[1] Besides humans, P. megistus is known to feed on birds, rodents, horses, dogs, opossums and bats.[2]

P. megistus is frequently found in domestic dwellings in Brazil, while in other countries it is largely a wild species.[2] Within Brazil, P. megistus's range stretches from the northeast to the south of the country,[4] corresponding roughly with the Atlantic Forest region, though the species also occupies parts of the caatinga and cerrado ecoregions.[2] The states of Bahia and Minas Gerais have the highest populations of P. megistus in Brazil. In southern parts of the country, domestic colonization is rare.[1]

The species was described in 1835 by Hermann Burmeister, who termed it Conorhinus megistus.[5]: 130  It was identified as a vector for Chagas disease in Carlos Chagas's original 1909 description of the condition.[5]: 394  The insects are typically black in colour with red markings.[6]
