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

摘要: Triatoma pintodiasi has been described and recently grouped in the Rubrovaria subcomplex. T. was initially compared to carcavalloi by staining subsequently identified as circummaculata. However, after thorough examination, it observed be a cryptic species of circummaculata, based on morphological features, morphometric data, biochemical patterns hemolymph. Thus, this paper aims describe karyotype of, spermatogenesis in, pintodiasi, order elucidate reproductive biology taxonomy species. Sex chromosomes formed heteropyknotic chromocenter, compaction chromatin during prophase. contrast observations individualization sex chromosomes. The diploid chromosome set 2n = 22 (20A + XY) is through analysis metaphases I II. Initial cytogenetic characteristics are differences chromocenter suggested possible cytotaxonomic tool. To gain better understanding specific status species, however, we emphasize need for further cytogenetic, molecular, biological, biogeographical analysis, addition experimental hybrid crosses with other
