We thank I. Córdova and M. Arenas for helping to collect insects in the field, N. Villarroel for laboratory assistance, D. Morata for helpful discussion on the geology of Chile. We especially thank B. Arriaza, A. Moreno, J. González and CONAF for insect collecting sites, S. Catalá for sharing some insect samples. This work was financed by FONDECYT 1085154 (AS), and partially by FONDECYT 11090086 (CBM) and PUCV 122.722/2011 (FTP). R. Campos was supported by a CONICYT-PhD fellowship.

N2 - 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° 30'-26° 30' S) M. spinolai (26° 30'-34° 20' S) and the recently described M. parapatrica in intermediate zones (24° 36'-26° 51' 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.
