Observaram-se caracteres morfológicos da cabeça, tórax, abdômen e de ovos. Foram consultadas as descrições morfológicas de 19 espécies de Rhodnius, porém exame mais detalhado foi realizado comparativamente com R. prolixus e R. robustus que ocorrem na região Norte do Brasil. Observou-se também exemplares de 18 espécies de Rhodnius depositadas no Laboratório Nacional e Internacional de Referência de Taxionomia de Triatomíneos do Instituto Oswaldo Cruz, Rio de Janeiro, Brasil. Os caracteres morfológicos mais notáveis que distinguem R. marabaensis n. sp. são o vértice da cabeça em forma de quilha, o comprimento do segundo segmento da antena, forma do prosterno, mesosterno, metasterno, conjunto de manchas no abdômen, genitália masculina, faces posterior e ventral da genitália externa feminina e os caracteres morfológicos de ovos. A análise filogenética do fragmento do gene Cytb também mostrou diferenças com outras sete espécies de Rhodnius avaliadas. Como foram examinados exemplares de Rhodnius jacundaensis Serra, Serra & Von Atzingen, 1980 [nomen nudum] depositados na Casa da Cultura de Marabá essa espécie entra em sinonímia com R. marabaensis n. sp., pois foi verificado que se tratavam da mesma espécie. / The species Rhodnius marabaensis sp. is described. It was collected in May 2014 in the Murumurú Environmental Reserve in the city of Marabá, Pará State, Brazil. The morphological characteristics of the head, thorax, abdomen, and eggs have been determined. The morphological descriptions of 19 previously described Rhodnius species were consulted; however, R. prolixus and R. robustus, which also occur in the northern region of Brazil, were examined in more detail. The exam included specimens from 18 Rhodnius species held in the Brazilian National and International Triatomine Taxonomy Reference Laboratory at the Oswaldo Cruz Institute in Rio de Janeiro, Brazil. The most notable morphological features that distinguish R. marabaensis sp. nov. are the keel-shaped apex of the head, the length of the second segment of the antennae, the shapes of the prosternum, the mesosternum, and the metasternum, the set of spots on the abdomen, the male genitalia, the posterior and ventral surfaces of the external female genitalia, and the morphological characteristics of the eggs. A phylogenetic analysis revealed that this species’ cyt-b gene fragment differed from the other seven Rhodnius species that were evaluated. Rhodnius jacundaensis Serra, Serra & Von Atzingen, 1980 [nomen nudum] specimens deposited in the Marabá Cultural Center were examined and were found to be synonymous with R. marabaensis sp. nov. / CNPq: 162356/2013-7
