title: Karyotype and spermatogenesis in  Triatoma lenti (Hemiptera:  Triatominae), a potential Chagas  vector.
abstract: All species of Triatominae are susceptible to infection by Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae) and consequently, potential insect vectors of Chagas disease. Currently, there are 140 known species of triatomine bugs, which can be grouped into specific species complexes. The species Triatoma lenti (Hemiptera: Triatominae) is found only in Brazil and is considered a potential vector of Chagas disease. We karyotyped male T. lenti and examined its spermatogenesis in detail. The karyotype was found to be 2n = 20A + XY, demonstrating that this organism has the modal chromosome set found in triatomines. This new information concerning males of this species contributed to biological data that will be useful for understanding this potentially important Chagas disease vector.
