Abstract

Assassin bugs (Hemiptera: Reduviidae Latreille) comprise not only one of the largest radiations of predatory animals (22 subfamilies; >6,800 spp.) but also include the medically important kissing bugs (Triatominae Jeannel). Reduviidae are morphologically diverse, engage in an astounding array of predatory strategies and have evolved some of the most unique anti‐predator and stealth techniques in the animal kingdom. While significant progress has been made to reveal the evolutionary history of assassin bugs and revise their taxonomy, the non‐monophyly of the second largest assassin bug subfamily, Reduviinae Latreille, remains to be addressed. Leveraging phylogenomic data (2,291 loci) and 112 morphological characters, we performed the first data‐ and taxon‐rich (195 reduvioid taxa) combined phylogenetic analysis across Reduvioidea and reconstructed morphological diagnostic features for major lineages. We corroborated the rampant polyphyly of Reduviinae that demands substantial revisions to the subfamilial and tribal classification of assassin bugs. Our new classification for Reduviidae reduces the number of subfamilies to 19 and recognizes 40 tribes. We describe three new subfamilies to accommodate distantly related taxa previously classified as Reduviinae (Heteropinae subfam. nov., Nanokeralinae subfam. nov., and Pasirinae subfam. nov.). Triatominae sensu nov. are expanded to include closely related predatory reduviine genera. Cetherinae Jeannel, Chryxinae Champion, Pseudocetherinae Villiers, Salyavatinae Amyot & Serville and Sphaeridopinae Amyot & Serville are treated as junior synonyms of Reduviinae sensu nov. Epiroderinae Distant are synonymized with Phimophorinae Handlirsch sensu nov. and Bactrodini Stål stat. nov. are reclassified as a tribe of Harpactorinae Amyot & Serville. Psophidinae Distant is treated as a valid subfamily. This new classification represents a robust framework for future taxonomic and evolutionary research on assassin bugs.Zoobank Registration: http://zoobank.org/urn:lsid:zoobank.org:pub:2310C9AA-0D53-4EF6-9E75-C2B3A98CE096

基于系统发生组和形态学数据综合分析的刺蝽分类修订版（半翅目：异翅目：红蝽科

暗杀蝽（半翅目：Reduviidae Latreille）不仅是掠食性动物（22 个亚科；6800 种）中最大的类群之一，而且还包括医学上重要的接吻蝽（Triatominae Jeannel）。红腹角蝇科动物形态多样，捕食策略惊人，并进化出动物界中一些最独特的反捕食和隐身技术。尽管在揭示刺蝽的进化历史和修订其分类学方面取得了重大进展，但第二大刺蝽亚科--Reduviinae Latreille--的非单系问题仍有待解决。利用系统发生组数据（2291个位点）和112个形态特征，我们首次对Reduvioidea进行了数据和类群丰富（195个Reduvioid类群）的综合系统发生分析，并重建了主要类群的形态诊断特征。我们证实了Reduviinae猖獗的多型性，需要对刺蝽的亚科和部族分类进行重大修订。我们新的 Reduviidae 分类将亚科数量减少到 19 个，并承认了 40 个支系。我们描述了三个新的亚科，以容纳以前被归类为 Reduviinae 的远缘类群（Heteropinae 亚科新种、Nanokeralinae 亚科新种和 Pasirinae 亚科新种）。Triatominae sensu nov.扩大到包括密切相关的捕食性 reduviine 属。Cetherinae Jeannel, Chryxinae Champion, Pseudocetherinae Villiers, Salyavatinae Amyot & Serville and Sphaeridopinae Amyot & Serville are treated as junior synonyms of Reduviinae sensu nov.Epiroderinae Distant 与 Phimophorinae Handlirsch sensu nov.同名，Bactrodini Stål stat.Psophidinae Distant 被视为一个有效的亚科。这一新的分类法为今后刺蝽的分类和进化研究提供了一个强有力的框架。Zoobank 注册：http://zoobank.org/urn:lsid:zoobank.org:pub:2310C9AA-0D53-4EF6-9E75-C2B3A98CE096
