Triatominae (Hemiptera: Reduviidae): Systematic questions and some others

Abstract: Triatominae (Hemiptera: Reduviidae): Questões Sistemáticas e Algumas Outras RESUMO -Os vetores da doença de Chagas são classificados como membros dos reduviídeos da subfamília Triatominae. Entretanto, essa classificação tem sido referida como incorreta por alguns autores, que consideram que alguns (ou todos?) os grupos de Triatominae têm diferentes ancestrais não-triatomíneos. Neste artigo essa questão é discutida amplamente e outras questões relacionadas ao tema são também levantadas, em particular a posição … Show more

“…Currently, despite ongoing debate, there is no consensus in the literature as to whether haematophagy developed independently in several lineages of Triatominae or perhaps Reduviidae, or whether a common haematophagous ancestral stock gave rise to all modern triatomine groups. For current views on the controversies of evolutionary relationships of Triatominae see Hypša et al (2002), Galvão (2003), Schaefer (2003) and Sainz et al (2004). Although haemolymphagy can be easier (apparently) for the young nymphs of B. herreri, our morphological results show that the reduced size of metanotal plates in young instars could facilitate the ingestion of blood meal as hypothesized by Lent & Wygodzinsky (1979).…”

“…The authors point out that additional data are required to clarify the relations among the clades involved and that the disagreement of their results with previous studies is explained by the inclusion in their study of a greater number of taxa and the form of sampling them. It is appropriate to mention here that previously, authors like Hypša et al (2002), Schaefer (2003), and Patterson and Gaunt (2010) had admitted the possibility that the origin of this subfamily could include the paraphyletic hypothesis. The controversy is apparently disputing three propositions because at the moment, it is not clear whether the Triatominae subfamily descended from one (monophyletic) ancestor, more than one (polyphyletic) ancestors, or if the group includes the common ancestor but not all the descendants (paraphyletic).…”

However, this last possibility doesn't rule out the monophyly but simply suggests that the descendents available for the study are incomplete (Schaefer 2003(Schaefer , 2005. Studies done by Lent and Wygodzinsky (1979), Hypša et al (2002), Schaefer (2003Schaefer ( , 2005, Schofield and Galvão (2009), Bargues et al (2010), Stevens et al (2011), and Hwang and Weirauch (2012) offer critical discussions of the matter.…”

“…Novas análises com uso de um maior número de marcadores genéticos associadas ainda, aos padrões sistemáticos clássicos de morfologia, ecologia e comportamento, devem ser adicionadas para uma decisão filogenética adequada. Uma vez que isto não tem apenas relevância sistemática, mas, sérias implicações quanto às medidas de controle das espécies de vetores (Scheafer 2003(Scheafer , 2005.…”

“…O uso de marcadores moleculares para fins de análise cladística em Triatominae, auxilia na resolução desses impasses sistemáticos e também acirrou as questões sobre as hipóteses de origem monofilética e parafilética do grupo (Jurberg 2003;Scheafer 2003; (Zahler & Roth 1995) adaptado para triatomíneos por Lyman et al (1999). De cada exemplar adulto retirou-se os três pares de pernas e a cabeça.…”
