The ambush bugs (Heteroptera: Reduviidae: Phymatinae) are a diverse clade of predators known for their cryptic hunting behavior and morphologically diverse raptorial forelegs. Despite their striking appearance, role as pollinator predators, and intriguing biogeographic distribution, phylogenetic relationships within Phymatinae are largely unknown and the evolutionary history of the subfamily has remained in the dark. We here utilize the most extensive molecular phylogeny of ambush bugs to date, generated from a 3328 base pair molecular dataset, to refine our understanding of phymatine relationships, estimate dates of divergence (BEAST 2), and uncover historical biogeographic patterns (S-DIVA and DEC). This taxon set (39 species of Phymatinae and six outgroups) allowed reevaluation of the proposed sister group of Phymatinae and tribal-level relationships within the group, and for the first time proposes species-level relationships within Phymata Latreille, the largest genus of ambush bugs (∼109spp.). Available evidence suggests that Phymata originated in the Neotropical region, with subsequent dispersals to the Nearctic and Palearctic regions. This study provides a framework for future research investigating the evolutionary history of ambush bugs, as well as ecological and microevolutionary investigations.
伏击蝽（半翅目：猎蝽科：瘤蝽亚科）是一类多样的捕食性昆虫，以其隐秘的捕食行为和形态各异的捕捉足而闻名。尽管它们外形醒目、身为传粉者的捕食者且具有引人入胜的生物地理分布，但瘤蝽亚科内部的系统发育关系在很大程度上尚不清楚，该亚科的进化历史一直处于迷雾之中。我们在此利用迄今为止最广泛的伏击蝽分子系统发育研究，该研究基于一个3328个碱基对的分子数据集生成，以完善我们对瘤蝽亚科关系的理解，估计分歧时间（BEAST 2），并揭示历史生物地理模式（S-DIVA和DEC）。这个分类群集合（39种瘤蝽亚科昆虫和六个外类群）使得对瘤蝽亚科拟议的姐妹群以及该类群内部落级关系进行重新评估，并首次提出了瘤蝽属（伏击蝽最大的属，约109个物种）内的物种级关系。现有证据表明，瘤蝽起源于新热带地区，随后扩散到新北界和古北界地区。这项研究为未来调查伏击蝽进化历史以及生态和微观进化研究提供了一个框架。
