Resumen
The tribe Rhodniini is a monophyletic group composed of 24 species grouped in two genera:
Rhodnius and Psammolestes. Rhodnius is a paraphyletic genus formed by 21 species. The event of
paraphilia is supported by the greater evolutionary proximity of the species of the prolixus groups
with the genus Psammolestes than with the other groups of Rhodnius. Based on this phenomenon,
it was proposed the alteration of the genus of the species of Psammolestes to Rhodnius. Thus, we
performed experimental crosses between Psammolestes spp. and R. neglectus to assess the degree
of reproductive compatibility between Psammolestes and Rhodnius. Hybrids were not obtained for
intergeneric crosses. Based on this, we have demonstrated that Rhodnius and Psammolestes have
reproductive incompatibility. These data are important to confirm the validity of the specific status of
Psammolestes, based on the biological concept of the species.
