“…External female genitalia from the Triatominae subfamily have rarely been used to characterize triatomines [6,17] compared with male genitalia, which have been frequently used as one of the main taxonomic characteristics [5,12,18]. After studying external female genitalia from Panstrongylus herreri , P. megistus , R. colombiensis , R. prolixus , Triatoma infestans and T. vitticeps through scanning electron microscopy (SEM), Rosa et al [19] validated this morphology for taxonomy.…”

BackgroundAmong the vectors of Chagas disease (Hemiptera: Reduviidae:Triatominae), there are eighteen Rhodnius species described and some are difficult to identify. The aim of this article is to contribute to the specific identification of fourteen Rhodnius spp. through morphological characters of the external female genitalia.MethodsFemale abdomens were cut transversely. The specimens were then prepared for examination by using scanning electron microscopy.ResultsThe careful examination of the dorsal, posterior and ventral sides revealed characteristics that allowed the identification of each of the fourteen species.ConclusionThe use of external female genitalia as characteristics are proposed as a tool for specifically identifying Rhodnius species, and an identification key for these species is presented.

Rhodnius marabaensis sp. 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 19 Rhodnius species and compared to the identification key for the genus Rhodnius. The examination included specimens from 18 Rhodnius species 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 prolixus and Rhodnius robustus were 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 distinguish Rhodnius marabaensis sp. 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 jacundaensis Serra, Serra & Von Atzingen (1980) nomen nudum specimens deposited at the MCCFMaraba Cultural Center Foundation - were examined and considered as a synonym of Rhodnius marabaensis sp. n.

Because of its rarity, there are only four publications including descriptions of the morphological characters of Rhodnius amazonicus (Almeida et al, 1973;Lent and Wygodzinsky, 1979;Bérenger and Pluot-Sigwalt, 2002;Galvão, 2014), this one being the fifth. Almeida et al (1973) relied on the finding of a single female specimen, which was captured with light bait on October 24, 1965 in the Manaus-Itacoatiara road, Manaus city, Amazonas state, Brazil.…”

“…Although Almeida et al (1973) had firstly considered the specimen to be R. pictipes Stål 1872, after a careful examination, they concluded that it was a new species, R. amazonicus. Lent and Wygodzinsky (1979) did not consider R. amazonicus as a valid species, but they reached that conclusion without examining the holotype and relying on a comparative study based on photographs.…”

Rhodnius amazonicus Almeida et al. (1973) is a triatomine of rare occurrence. This species was found for the third time in Breves city, Pará state, Brazil. Morphometric and morphological studies were carried out on one male and one female. Lent and Wygodzinsky (1979) considered this species as a synonym of R. pictipes, until its revalidation after 23 years by Bérenger and Pluot-Sigwalt (2002). Considering the synonym mentioned above, a comparative study between these two species was performed in order to report the third encounter of this species, and increase the number of morphological characters that distinguish R. amazonicus from R. pictipes. The dorsal side of the head, the dorsal and ventral portions of the thorax, the dorsal, ventral and posterior sides of the female genitalia, eggs and the median process of the pygophore were examined by scanning electronic microscopy (SEM). The head, thorax, abdomen and egg parameters of these two species were also measured. The identification of characters on the head, stridulatory sulcus, mesosternum, metasternum, scutellum, process of urotergite I, external female genitalia, pygophore and eggs made the distinction between R. amazonicus and R. pictipes possible. This study has shown the new characters recorded and described for the first time for R. amazonicus and R. pictipes by SEM here made it possible to confirm the morphological separation between these two species. The morphometric analysis also confirmed that the above two taxa are different at specific level.
