The triatomines are hematophagous insects which belong to the order Hemiptera, suborder Heteroptera, family Reduviidae and subfamily Triatominae, they are popularly known as barbeiro, chupanca and other regional denominations. The epidemiological interest for the triatomines is related to the fact that these insects are vectors of the Trypanosoma cruzi , etiological agent of Chagas’ disease. The investigation was accomplished through the samples of triatomines in the entomologic collection of Iepa. This collection has a total of 32 samples of triatomines, which 21 are Rhodnius pictipes , 02 Panstrongylus geniculatus , 01 P. lignarius and 08 Eratyrus mucronatus. The species P. lignarius and E. mucronatus represent new records for the State of Amapa. The taxonomic identification and the publishing of this collection will contribute for the epidemiological analysis of the American Trypanosomiasis in Amapa, once; the recorded cases are conveyed only orally. It’s necessary the accomplishment of a most systematic studies, so that they will certainly reinforce a most significant sample of triatomines in the most varied ecotopes.
