Abstract

AbstractThe male reproductive tract in Triatominae has a pair of testes, two vasa deferentia, a pair of seminal vesicles, four pairs of accessory glands, and an ejaculatory duct, which opens in the aedeagus. In species of the genus Triatoma each testis is formed by seven testicular follicles. Because Triatoma rubrofasciata has a common ancestor with species of Triatoma occurring in North America and because the length of testis follicles varies among different species of Triatoma a morphometrical analysis of the follicles was conducted. Triatoma rubrofasciata has seven testis follicles of variable length that are similar between left and right testes. The statistics allowed the classification in a long follicle, two medium follicles, two that are short, and two that are very short. This finding is compared with data available for other Triatominae and it is emphasized that the length of follicles testis should be included in future phylogenetic analysis of Triatominae.
