Fossils provide primary material evidence for the pattern and timing of evolution. The newly discovered “beast ants” from mid-Cretaceous Burmite, †Camelospheciagen. nov., display an exceptional combination of plesiomorphies, including absence of the metapleural gland, and a series of unique apomorphies. Females and males, represented by †C. fossorsp. nov. and †C. venatorsp. nov., differ in a number of features which suggest distinct sexual biologies. Combined-evidence phylogenetic analysis recovers †Camelosphecia and †Camelomecia as a clade which forms the extinct sister group of the Formicidae. Notably, these genera are only known from alate males and females; workers, if present, have yet to be recovered. Based on ongoing study of the total Aculeata informed by the beast ant genera, we provide a brief diagnosis of the Formicoidea. We also provide the first comprehensive key to the major groupings of Mesozoic Formicoidea, alongside a synoptic classification in which †Zigrasimeciinaestat. nov. and †Myanmyrma marauderacomb. nov. are recognized. Finally, a brief diagnosis of the Formicoidea is outlined.

†Camelosphecia gen。11月,白垩纪中期(膜翅目,Formicoidea)丢失的蚂蚁黄蜂中间体

化石为演化的模式和时间提供了主要的物质证据。新发现的来自白垩纪中部Burmite†Camelospheciagen的“野兽蚂蚁”。十一月,显示异常形态的异常组合,包括不存在胸膜腺和一系列独特的无性形态。男性和女性,以†C表示。fosssp。十一月 和†C。venatorsp。十一月。,在许多特征上存在差异,这些特征暗示了不同的性生物学。综合证据系统发育分析可以发现†Camelosphecia和†Camelomecia是进化枝,形成了已灭绝的蚁科。值得注意的是,这些属仅在晚期雄性和雌性中已知;工人(如果存在)尚未恢复。在对野兽属告知的总Ac虫的持续研究的基础上,我们对甲虫进行了简要诊断。我们还提供了中生代蚁门类主要分类的第一个综合关键字,以及†Zigrasimeciinaestat的天气分类。十一月 和†Myanmyrma marauderacomb。十一月 被认可。最后,概述了甲虫的简要诊断。
