根据其物种数量（16，800种），刺客虫是最成功的食肉动物分支之一。广泛分布于陆地生态系统中。各种新颖的猎物捕获策略和显着的猎物专业化，有助于他们的吸引力，作为一个模型，研究参与捕食的进化途径。在这里，我们重建了最全面的reduviid系统发育（178个分类群，18亚科）的基础上的分子数据（5个标记）。该系统发育测试了当前关于猎蝽科关系的假设，强调了多系猎蝽亚科和吸血、传播疾病的锥蝽亚科，并使我们能够首次在猎蝽中重建猎物协会和微生境的祖先状态。使用化石校准的分子树，我们估计分歧时间的关键事件在Reduviidae的进化历史。我们的研究结果表明，多系的Reduviinae落入11 - 14个独立的分支。在最大似然分析中，Triatominae与Reduviine属Opisthacidius并系;这一结果与先前的假设相反，该假设认为Triatominae是单系或多系的，可能是由于本研究中更全面的分类和特征采样。因此，吸血的进化可能在捕食性猎蝽中独立发生过一两次。所有的猎物专家都是从多面手的祖先进化而来的，有着白蚁和蚂蚁专业化的多个进化起源。树干上与树皮相关的生活方式是大多数高等猎蝽科谱系的祖先;生活在树叶上至少独立进化了六次。Reduviidae起源于中侏罗世（178 Ma），但显着的谱系多样性，直到晚白垩世（97 Ma）才开始。本文提出的分子生物遗传学与化石和生活史数据的整合提供了对reduviids进化历史的见解，并为在最具物种多样性的捕食者分支之一中进行深入的进化假设检验扫清了道路。
Assassin bugs are one of the most successful clades of predatory animals based on their species numbers (∼6,800 spp.) and wide distribution in terrestrial ecosystems. Various novel prey capture strategies and remarkable prey specializations contribute to their appeal as a model to study evolutionary pathways involved in predation. Here, we reconstruct the most comprehensive reduviid phylogeny (178 taxa, 18 subfamilies) to date based on molecular data (5 markers). This phylogeny tests current hypotheses on reduviid relationships emphasizing the polyphyletic Reduviinae and the blood-feeding, disease-vectoring Triatominae, and allows us, for the first time in assassin bugs, to reconstruct ancestral states of prey associations and microhabitats. Using a fossil-calibrated molecular tree, we estimated divergence times for key events in the evolutionary history of Reduviidae. Our results indicate that the polyphyletic Reduviinae fall into 11–14 separate clades. Triatominae are paraphyletic with respect to the reduviine genus Opisthacidius in the maximum likelihood analyses; this result is in contrast to prior hypotheses that found Triatominae to be monophyletic or polyphyletic and may be due to the more comprehensive taxon and character sampling in this study. The evolution of blood-feeding may thus have occurred once or twice independently among predatory assassin bugs. All prey specialists evolved from generalist ancestors, with multiple evolutionary origins of termite and ant specializations. A bark-associated life style on tree trunks is ancestral for most of the lineages of Higher Reduviidae; living on foliage has evolved at least six times independently. Reduviidae originated in the Middle Jurassic (178 Ma), but significant lineage diversification only began in the Late Cretaceous (97 Ma). The integration of molecular phylogenetics with fossil and life history data as presented in this paper provides insights into the evolutionary history of reduviids and clears the way for in-depth evolutionary hypothesis testing in one of the most speciose clades of predators.
