INTRODUCTION:
This paper reports, for the first time, the presence of Rhodnius montenegrensis in the State of Acre, Brazil.
METHODS:
Two female R. montenegrensis were collected in a dwelling in the rural area of Rio Branco, Acre, Brazil.
RESULTS:
The occurrence of this species was confirmed, and the number of Triatominae species in the State of Acre increased from four to five.
CONCLUSIONS:
Further studies should be performed to reach a clearer understanding of the ecology of this arthropod, its possible role in transmitting Chagas' disease and rangeliosis, and its current geographical distribution in the region.
