Data from: Molecular phylogeny of Triatomini (Hemiptera: Reduviidae: Triatominae)

Background: The Triatomini and Rhodniini (Hemiptera: Reduviidae) tribes include the most diverse Chagas disease vectors; however, the phylogenetic relationships within the tribes remain obscure. This study provides the most comprehensive phylogeny of Triatomini reported to date. Methods: The relationships between all of the Triatomini genera and representatives of the three Rhodniini species groups were examined in a novel molecular phylogenetic analysis based on the following six molecular markers: the mitochondrial 16S; Cytochrome Oxidase I and II (COI and COII) and Cytochrome B (Cyt B); and the nuclear 18S and 28S. Results: Our results show that the Rhodnius prolixus and R. pictipes groups are more closely related to each other than to the R. pallescens group. For Triatomini, we demonstrate that the large complexes within the paraphyletic Triatoma genus are closely associated with their geographical distribution. Additionally, we observe that the divergence within the spinolai and flavida complex clades are higher than in the other Triatoma complexes. Conclusions: We propose that the spinolai and flavida complexes should be ranked under the genera Mepraia and Nesotriatoma. Finally, we conclude that a thorough morphological investigation of the paraphyletic genera Triatoma and Panstrongylus is required to accurately assign queries to natural genera.背景：锥蝽族（Triatomini）与红猎蝽族（Rhodniini）隶属于半翅目（Hemiptera）猎蝽科（Reduviidae），是恰加斯病（Chagas disease）多样性最高的传播媒介类群；然而，两族内部的系统发育关系仍不明晰。本研究构建了目前已报道的最为全面的锥蝽族系统发育树。 方法：本研究基于6种分子标记开展新型分子系统发育分析，对所有锥蝽族属级类群以及红猎蝽族3个物种群的代表类群间的演化关系进行了探究。所用分子标记包括：线粒体16S rRNA、细胞色素氧化酶I、II（COI、COII）与细胞色素B（Cyt B），以及核基因18S和28S。 结果：本研究结果显示，红猎蝽属（Rhodnius）的长红猎蝽群（R. prolixus）与绘斑红猎蝽群（R. pictipes）之间的亲缘关系，较二者与淡色红猎蝽群（R. pallescens）的亲缘关系更近。针对锥蝽族的分析表明，并系锥蝽属（Triatoma）内的多个大型复合群，其演化关联与其地理分布高度相关。此外，本研究还发现，斯皮诺莱复合支系（spinolai complex clades）与黄褐复合支系（flavida complex clades）内部的遗传分化程度，高于其余锥蝽属复合群。 结论：本研究建议将斯皮诺莱复合群与黄褐复合群归入梅普猎蝽属（Mepraia）与新锥蝽属（Nesotriatoma）。最后，本研究认为，为实现待鉴定类群的精准自然属级归类，需对并系锥蝽属（Triatoma）与强喙猎蝽属（Panstrongylus）开展全面的形态学研究。
