Abstract
dc.description.abstract
The hematophagous Hemiptera of the subfamily Triatominae are a very diverse group with a variety of
morphs, behaviors and distributions. They have great epidemiological importance because many of its
members are vectors of the protozoan Trypanosoma cruzi, the agent of Chagas disease. Mepraia is a genus
of Triatominae endemic to Chile responsible for transmitting T. cruzi in the sylvatic cycle. Mepraia
includes three species, M. gajardoi (18 300–26 300 S) M. spinolai (26 300–34 200 S) and the recently
described M. parapatrica in intermediate zones (24 360–26 510 S). Using mitochondrial DNA sequences,
we inferred historical processes that led to the current structure of populations. Phylogeographic analyses
identified three lineages, congruent with current taxonomy, and populations were highly structured.
The times to the most recent common ancestor suggest that M. spinolai is the oldest lineage. We discuss
the taxonomic and biogeographic implications of our results.
