Post-zygotic reproductive barriers confirm absence of continuous interspecific gene flow between Mepraia spp. (Hemiptera, Triatominae) by Jader de Oliveira, Kaio Cesar Chaboli Alevi, Amanda Ravazi, Jociel Klleyton S. Santana, Daniel Frias Lasserre, João Aristeu da Rosa, Cleber Galvão, Mauro Toledo Marrelli

“…Even though hybrids have been obtained in all directions, the combination of different evolutionary events demonstrated here, such as low hatching rate and high mortality rate of hybrids, as well as the presence of post-zygotic reproductive barriers and possible action of Haldane’s rule indicate that there is no continuous interspecific gene flow between Mepraia spp. and confirms the specific status of species based on the biological species concept.…”
