Description ofRhodnius marabaensissp. n. (Hemiptera, Reduviidae, Triatominae) from Pará State, Brazil.
Rhodnius marabaensissp. n.was collected on 12 May 2014 in the Murumurú Environmental Reserve in the city of Marabá, Pará State, Brazil. This study was based on previous consultation of morphological descriptions of 19Rhodniusspecies and compared to the identification key for the genusRhodnius. The examination included specimens from 18Rhodniusspecies held in the Brazilian National and International Triatomine Taxonomy Reference Laboratory in the Oswaldo Cruz Institute in Rio de Janeiro, Brazil. The morphological characteristics of the head, thorax, abdomen, genitalia, and eggs have been determined.Rhodnius prolixusandRhodnius robustuswere examined in more detail because the BLAST analysis of a cyt-b sequence shows they are closely related to the new species, which also occurs in the northern region of Brazil. The most notable morphological features that distinguishRhodnius marabaensissp. n.are the keel-shaped apex of the head, the length of the second segment of the antennae, the shapes of the prosternum, mesosternum and 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.Rhodnius jacundaensisSerra, Serra & Von Atzingen (1980)nomen nudumspecimens deposited at the Maraba Cultural Center Foundation - MCCF were examined and considered as a synonym ofRhodnius marabaensissp. n.
