Triatoma pintodiasi sp. nov. do subcomplexo T. rubrovaria (Hemiptera, Reduviidae, Triatominae)

Abstract

RESUMOUma nova espécie críptica de Triatoma é descrita dentro do subcomplexo T. rubrovaria. As diferenças entre T. pintodiasi sp. nov. e T. circummaculata incluem, entre outras, o padrão cromático e diferenças morfológicas nas estruturas fálicas, como nos parâmeros, suporte do falosoma, processo do endosoma e vesica. Análises bioquímicas realizadas na hemolinfa e a comparação morfométrica da cabeça também registraram diferenças entre as duas espécies e outras do subcomplexo T. rubrovaria. Palavras

Description of the diploid chromosome set of Triatoma pintodiasi (Hemiptera, Triatominae)

“…The 148 species currently described (Abad-Franch et al, 2013;Alevi et al, 2013a;Jurberg et al, 2013;Poinar Jr., 2013) are potential vectors of the protozoan Trypanosoma cruzi, the etiologic agent of Chagas disease. Triatomines are also of biological interest because their cells have several peculiarities in comparison to cells of other eukaryotes, such as holocentric chromosomes (Panzera et al, 1996), inverted meiosis for sex chromosomes (Gómez-Palacio et al, 2008), and persistence of nucleolar material during meiosis (Tartarotti and Azeredo-Oliveira, 1999;Alevi et al, 2014a).…”

Mitochondrial Gene Confirms the Specific Status of Triatoma pintodiasi Jurberg, Cunha, and Rocha, 2013 (Hemiptera, Triatominae), an Endemic Species in Brazil

“…These results highlight the specific status of the species. They reflect the importance of the analysis used by Jurberg and others 5 in the description of new species, particularly in the study of the phenomenon of cryptic speciation.…”

“…3 Among the species in Rio Grande do Sul, T. rubrovaria, T. oliveirai, T. pintodiasi, T. klugi, T. carcavalloi, and T. circummaculata (with the addition of Triatoma limai, which is endemic to Argentina) 4 make up the T. rubrovaria subcomplex. 5 The last species described and grouped into this subcomplex was T. pintodiasi. 5 The description was based on chromatic, morphological, morphometric, and biochemical aspects of the species, which led the author to describe T. pintodiasi as a cryptic species of T. circummaculata.…”

“…5 The last species described and grouped into this subcomplex was T. pintodiasi. 5 The description was based on chromatic, morphological, morphometric, and biochemical aspects of the species, which led the author to describe T. pintodiasi as a cryptic species of T. circummaculata.…”

“…However, new comparative analyses were encouraged. 2,5 Thus, this study characterized the genetic distance between the mitochondrial 16S rDNA gene of T. pintodiasi and that of the members of the T. rubrovaria subcomplex to evaluate the specific status of T. pintodiasi.…”
