“…Campos et al ( 2013 ) found three lineages of Mepraia , congruent with the current recognized species. All populations tested were highly structured, suggesting that they have not been affected by strong bottlenecks and/or experienced sudden demographic changes due to repeated climatic fl uctuations.…”

A review of Heteroptera classifi cation, biogeography, and phylogeography is presented. The use of molecular data signifi cantly expanded the knowledge of phylogenetic relationships among and within heteropteran infraorders. However, taxa historically less studied continue to receive little attention. Promising, new molecular approaches with increased genetic markers and broader taxon sampling, as well as new morphological approaches (e.g., microtomography), are the future for more stable classifi cations and a better comprehension of the heteropteran evolutionary history, but their application is still incipient. A non-exhaustive overview of studies about Neotropical heteropteran biogeography is made and discussed, including those about intercontinental connections and regional distribution patterns. The most comprehensible studies, and more promising area, seem to be those focused on distribution patterns, especially employing macroecological methods, and trying to elucidate what are the major factors responsible for the distribution of the group in the Neotropics. Finally, we present an overview of phylogeographic studies involving Neotropical Heteroptera. It is clear that the best biogeographic and phylogeographic studied groups are those with medical and economical importance (e.g., Reduviidae and Pentatomidae).

“…The results reported by Canals et al (1999) for M. spinolai and T. infestans suggest that because of the differences in their defaecation behaviour once they feed on their hosts, T. infestans would be a better vector than M. spinolai that takes more time to release their droppings, whereas T. infestans do so immediately. When considering the results of Canals et al (1999) for M. spinolai, and because M. gajardoi is a close species to M. spinolai and part of the Spinolai complex as suggested by Campos et al (2013aCampos et al ( , 2013b, this species could also delay defaecation on hosts, which would make it a less-efficient vector under natural conditions.

Four species of triatomines are known from Chile: Triatoma infestans Klug, Mepraia spinolai Porter, M. gajardoi Frías, Henry & González, and M. parapatrica Frías (Hemiptera: Reduviidae), the last three are endemic. The geographical distribution of M. gajardoi includes the coastal areas in the north of Chile between 18° and 21°S, an area with both a resident workforce and summer-season visitors. A study was developed to assess the risk of vectorial transmission of Chagas disease by M. gajardoi in hut settlements on the coast of the Tarapacá Region, in particular in Caleta San Marcos and Caleta Río Seco. The study comprised fingerstick sampling of 95 persons, venous samples from 29 domestic dogs and capture of 52 triatomines, from both fishing coves. The samples were analysed by enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) techniques. The results show that, of the total number of persons studied, 100% were negative for Trypanosoma cruzi Chagas (Trypanosomatida: Trypanosomatidae) antibodies, 10.34% of canids were positive for the antibody and 5.8% of M. gajardoi were infected to the PCR technique. The presence of this species in areas close to human settlements constitutes a risk to human populations established on the coast of northern Chile.

“…Toledo et al () collected 397 adults and nymphs of M. gajardoi at five locations in the coastal region of northern Chile. Campos et al () collected 65 of M. gajardoi , 27 of M. parapatrica, and 72 of M. spinolai , including adults and nymphs, in 13 localities located between 18º and 33º S of the coastal region and valleys in the interior of Chile. Egaña et al () collected 70 3 rd , 4 th , and 5 th instar nymphs of M. gajardoi in the northern zone of Chile and 65 nymphs of 3 rd , 4 th , and 5 th instars of M. spinolai in central Chile.…”
