AbstractTrypanosoma cruzi, the causative agent of Chagas disease, is transmitted to mammals - including humans - by insect vectors of the subfamily Triatominae. We present the results of a compilation of triatomine occurrence and complementary ecological data that represents the most complete, integrated and updated database (DataTri)available on triatomine species at a continental scale. This database was assembled by collecting the records of triatomine species published from 1904 to 2017, spanning all American countries with triatomine presence. A total of 21815 georeferenced records were obtained from published literature, personal fieldwork and data provided by colleagues. The data compiled includes 24 American countries, 14 genera and 135 species. From a taxonomic perspective, 67.33% of the records correspond to the genusTriatoma, 20.81% toPanstrongylus, 9.01% toRhodniusand the remaining 2.85% are distributed among the other 11 triatomine genera. We encourage usingDataTriinformation in various areas, especially to improve knowledge of the geographical distribution of triatomine species and its variations in time.
