These species have a large intraspecific variability together with an overall similarity, making difficult to establish their taxonomic status. Many cytogenetic, morphometric, and molecular markers have been applied to address this. Recent studies have posed concerns on the inclusion of T. guasayana and T. patagonica within the subcomplex. Also, T. sordida from Argentina has been designed as a new species, Triatoma rosai. Using the cuticular hydrocarbon pattern as chemotaxonomic marker, the relationships among several populations of these species were analyzed by capillary gas chromatography and linear discriminant analysis along 25 collection sites in Argentina, Bolivia, Brazil, and Paraguay. T. sordida and T. rosai populations were differentially clustered in two CHC-based groups: \u201cGroup 1\u201d included T. sordida from Eastern Brazil, Eastern Paraguay, and the Bolivian populations from La Paz and Izozog G1; \u201cGroup 2\u201d included T. rosai, and T. sordida from Izozog G2 (Bolivia), and Western Paraguay. Whereas T. garciabesi remained closely related to T. sordida and T. rosai, T. guasayana, and T. patagonica were clearly separated from the species of the T. sordida subcomplex. Our results agree with those from other several techniques suggesting that the taxonomy of the T. sordida subcomplex should be revised.<\/jats:p>","DOI":"10.1093\/jme\/tjab199","type":"journal-article","created":{"date-parts":[[2021,12,11]],"date-time":"2021-12-11T03:38:50Z","timestamp":1639193930000},"page":"554-564","source":"Crossref","is-referenced-by-count":5,"title":["Chemotaxonomy of Five South American Species of the<i>Triatoma<\/i>genus (Hemiptera: Reduviidae: Triatominae) Based on Their Cuticle Hydrocarbon Pattern"],"prefix":"10.1093","volume":"59","author":[{"given":"D\u00e9bora E","family":"Moriconi","sequence":"first","affiliation":[{"name":"Instituto de Investigaciones Bioqu\u00edmicas de La Plata (INIBIOLP), Facultad de Ciencias M\u00e9dicas, La Plata, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catarina","family":"Macedo-Lopes","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio Interdisciplinar de Vigil\u00e2ncia Entomol\u00f3gica em Diptera e Hemiptera, Instituto Oswaldo Cruz, Manguinhos, Rio de Janeiro, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adriana","family":"Sartorio","sequence":"additional","affiliation":[{"name":"School of Mathematical and Natural Sciences, Arizona State University, Glendale, AZ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M Patricia","family":"Ju\u00e1rez","sequence":"additional","affiliation":[{"name":"Instituto de Investigaciones Bioqu\u00edmicas de La Plata (INIBIOLP), Facultad de Ciencias M\u00e9dicas, La Plata, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan R","family":"Girotti","sequence":"additional","affiliation":[{"name":"Instituto de Investigaciones Bioqu\u00edmicas de La Plata (INIBIOLP), Facultad de Ciencias M\u00e9dicas, La Plata, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2279-6209","authenticated-orcid":false,"given":"Gustavo M","family":"Calder\u00f3n-Fern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Instituto de Investigaciones Bioqu\u00edmicas de La Plata (INIBIOLP), Facultad de Ciencias M\u00e9dicas, La Plata, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2021,12,10]]},"reference":[{"key":"2022031611060556700_CIT0001","doi-asserted-by":"crossref","first-page":"180","DOI":"10.1186\/s13071-017-2129-1","article-title":"Triatoma vitticeps subcomplex (Hemiptera, Reduviidae, Triatominae): a new grouping of Chagas disease vectors from South America","volume":"10","author":"Alevi","year":"2017","journal-title":"Parasit.
