“…There are morphological and genetic differences among the two species here studied which led to their recognition as separate species [62]; nevertheless, these differences were previously considered not to warrant them separation at the species level by Abad-Fanch [18]. The few morphological differences identified may be a consequence of recent divergence, however, the current SNP analysis shows that 5,562 (40.6%) of the SNPs identified were fixed between the species (Fig 2).…”

Differential transcriptome analysis supports Rhodnius montenegrensis and Rhodnius robustus (Hemiptera, Reduviidae, Triatominae) as distinct species

Chagas disease is one of the main parasitic diseases found in Latin America and it is estimated that between six and seven million people are infected worldwide. Its etiologic agent, the protozoan Trypanosoma cruzi, is transmitted by triatomines, some of which from the genus Rhodnius. Twenty species are currently recognized in this genus, including some closely related species with low levels of morphological differentiation, such as Rhodnius montenegrensis and Rhodnius robustus. In order to investigate genetic differences between these two species, we generated large-scale RNA-sequencing data (consisting of four RNA-seq libraries) from the heads and salivary glands of males of R. montenegrensis and R. robustus. Transcriptome assemblies produced for each species resulted in 64,952 contigs for R. montenegrensis and 70,894 contigs for R. robustus, with N50 of approximately 2,100 for both species. SNP calling based on the more complete R. robustus assembly revealed 3,055 fixed interspecific differences and 216 transcripts with high levels of divergence which contained only fixed differences between the two species. A gene ontology enrichment analysis revealed that these highly differentiated transcripts were enriched for eight GO terms related to AP-2 adaptor complex, as well as other interesting genes that could be involved in their differentiation. The results show that R. montenegrensis and R. robustus have a substantial quantity of fixed interspecific polymorphisms, which suggests a high degree of genetic divergence between the two species and likely corroborates the species status of R. montenegrensis.

“…Fifteen males and 15 females were measured together with 15 eggshells (Naegele et al 2003;Rosa et al 2003). The characters measured were: total length of the triatomines (TL), length of the head (HL), length of the antenna segments (A1, A2, A3, and A4) and rostrum segments (R1, R2, and R3), inner distance between eyes (IE), anteocular (AO) and post-ocular distances (PO), diameter of the eye (DE), maximum abdomen (MWA) and thorax widths (MWT), eggshell area, length, width, and diameter of the opercular aperture (Lent and Wigodzinsky 1979;Dujardin et al 1999a;Rosa et al 2000).…”

We present here a multisource approach that takes advantage of several disciplines to address a taxonomic issue. A triatomine related to Rhodnius robustus Larrousse, 1927 was recently found in the state of Rondônia, Brazil. The name Rhodnius montenegrensis n. sp. is suggested because it was found in the municipality of Monte Negro. The main differences between these two species can be detected in the female and male genitalia, but there are also noticeable differences in their eggs. Molecular analysis using PCR-RFLP technique and Bayesian inferences based on a fragment of the Cytochrome b (Cyt b) gene corroborated the morphological findings. We used this integrative approach to address the taxonomic decision for a new Rhodnius species and its relationship with others of this genus. Results obtained herein stress that morphology must be used as the major approach for obtaining phenotypic information, and molecular data should be taken as a complementary tool.

“…Barata (1981) used both OM and SEM to enable detailed descriptions of the macroscopic and exochorial characteristics of 10 species from the genus Rhodnius (Stål, 1859) and created a key for classifying species by egg morphology. Various authors (Rosa et al 2000(Rosa et al , 2003 have since adopted this approach. After Barata (1981), many species have been described or re-described on the basis of egg morphology (Sandoval et al 2007).…”
