    <i>Culex (Culex) acharistus,</i> Root, 1927 (Diptera: Culicidae), a new record for Bolivia

    Abstract This study reports the first confirmed records of Culex (Culex) acharistus, Root, 1927 in Bolivia, based on both morphological examination and biomolecular identification using the cytochrome c oxidase subunit I (COI) marker. Specimens were collected in four localities representing diverse environmental settings: La Paz (urban environment, ≍3600 m), the nearby high-altitude city of El Alto (≍4000 m), Cochabamba (semi-rural and urban habitats, ≍2600 m), and Licoma a large village in the Yungas region (subtropical environment, ≍1900 m). The larval habitats where the species was found closely match those reported in neighboring countries where Cx. acharistus also occurs, ranging from typical small peridomestic sites to ponds, ditches, and river seepages in semi-rural areas. All identification methods yielded unambiguous results, confirming the species’ presence in Bolivia and extending its known distribution in South America. This finding highlights the importance of integrating morphological and molecular approaches to achieve accurate and reliable mosquito species identification.

    Presence of Triatoma breyeri (Reduviidae, Triatominae) in Bolivia
    (Public Library of Science, 2024) Frédéric Lardeux; Alberto Llanos; Roberto Rodríguez; Luc Abate; Philippe Boussès; Rosenka Lardeux; Christian Barnabé; Lineth García
    The study focuses on identifying and understanding the ecological dynamics of Triatoma breyeri in Bolivia. Morphological identification and molecular analysis using gene fragments (COI, CytB and 16S) confirms T. breyeri's presence and its relation to other species. The species has been consistently found in the Estancia-Mataral-La Palma region since 2010 but has not spread to other regions in Bolivia. The region of occurrence is a small characteristic dry inter-Andean valley. A MaxEnt model suggests part of the Bolivian Montane Dry Forest ecoregion serves as a unique habitat within its range. The infrequent presence in Bolivia and the distance from its main range in Argentina suggest recent accidental introduction, possibly through human transport. Further research is needed to comprehend its persistence in this small area of Bolivia.
