Rio Grande do Sul . Public health importance. Triatoma platensis is a sylvatic and ornitophilic species. It can be found in the nests of furnariid bird ( Salvatella et al. 1991 , Turienzo and Di Iorio 2014 , Marti et al. 2014 ) and occasionally in peridomestic habitats, such as in hens’ coop. The natural infection of T. platensis by T. cruzi was reported ( Lent and Wygodzinsky 1979 , Marti et al. 2014 ). Remarks. This species is closely related to T . delpontei , T . rubrovaria , and T . infestans . It can be fertile with T . delpontei and occasionally natural hybrids of T. infestans x T. platensis were found in places of their occurrence ( Abalos 1948 , Lent and Wygodzinsky 1979 , Ronderos et al. 1980 ). Crocco et al. (2010) reported that T. platensis defecates quickly after feeding.
