Introduction: This short communication presents a novel report on the occurrence of Panstrongylus rufotuberculatus in the Brazilian state of Rondônia.
Methods: Two specimens were collected inside dwellings and identified using dichotomous keys.
Results: The present study showed the extensive geographic distribution of P. rufotuberculatus and the increased number of species in the state of Rondônia.
Conclusions: This new record of P. rufotuberculatus is important for understanding the epidemiology of Chagas disease because this species is found naturally infected with Trypanosoma cruzi. Studies on the ecology, biology, and vector-host-parasite interactions of this species are essential for surveillance programs.

is a Neotropical taxa of 16 species, some more widespread than others, that act as vectors of , the etiologic agent of Chagas disease (CD). This group is associated with mammalian reservoir niches. There are few studies of the biogeography and niche suitability of these triatomines.

Chagas disease is a significant public health risk in rural and semi-rural areas of Venezuela. Triatomine infection by the aetiological agent Trypanosoma cruzi is also observed in the Metropolitan District of Caracas (MDC), where foodborne T. cruzi outbreaks occasionally occur but active vector-to-human transmission (infection during triatomine bloodmeal) is considered absent.

Background: This study is the first report of the species Panstrongylus rufotuberculatus in Roraima, a state in northern Brazil.
Methods: We collected specimens from a residence in the municipality of Rorainópolis.
Results: Our findings confirmed the occurrence of this species in Roraima, increasing the number of registered species from six to seven.

Chagas' disease is transmitted mainly by members of the subfamily Triatominae (Hemiptera: Reduviidae). Among them, Triatoma infestans (Klug) is the main vector of the disease in Southern Cone of Latin America. In order to contribute to knowledge of the genetic variation between triatomine vectors, in the present study, we analyzed the intraspecific and interspecific variations of the seven mitogenomes available from Triatominae.
