Augochlorini comprise 646 described bee species primarily distributed in the Neotropical region. According to molecular and morphological phylogenies, the tribe is monophyletic and subdivided into seven genus groups. Our main objective is to propose a revised phylogeny of Augochlorini based on a comprehensive data set including fossil species as terminals and new characters from the internal skeleton. We also aim to develop a total-evidence framework incorporating a morphological-partitioned homoplasy approach and molecular data and propose a detailed biogeographic and evolutionary scenario based on ancestor range estimation. Our results recovered Augochlorini and most genus groups as monophyletic, despite some uncertainties about monophyly of the Megalopta and Neocorynura groups. The position of the cleptoparasite Temonosoma is still uncertain. All analyses recovered Augochloropsis s.l. as related to the Megaloptidia group. Internal characters from the head, mesosoma and sting apparatus provided important synapomorphies for most internal nodes, genus groups and genera. Augochlorini diversification occurred in the uplands of the Neotropical region, especially the Brazilian Plateau. Multiple dispersals to Amazonia, Central America and North America with returns to the Atlantic endemism area were recovered in our analysis. Total evidence, including morphological partitioning, was shown to be a reliable approach for phylogenetic reconstruction.

全证据测年和形态划分:一种了解金绿蜂系统发育和生物地理学的新方法(膜翅目:Apoidea)

Augochlorini 包括 646 种已描述的蜜蜂物种,主要分布在新热带地区。根据分子和形态系统发育,该部落是单系的,并细分为七个属群。我们的主要目标是基于包括化石物种作为终端的化石物种和来自内部骨骼的新特征在内的综合数据集,提出修订后的 Augochlorini 系统发育。我们还旨在开发一个包含形态分区同质化方法和分子数据的全证据框架,并基于祖先范围估计提出详细的生物地理和进化方案。我们的结果将 Augochlorini 和大多数属群恢复为单系,尽管关于 Megalopta 和 Neocorynura 群的单系存在一些不确定性。钩虫Temonosoma的位置仍然不确定。所有分析都恢复了与 Megaloptidia 组相关的 Augochloropsis sl。来自头部、中体和刺装置的内部特征为大多数内部节点、属群和属提供了重要的突触。Augochlorini 多样化发生在新热带地区的高地,特别是巴西高原。在我们的分析中恢复了向亚马逊流域、中美洲和北美洲的多次扩散,并返回大西洋特有地区。包括形态分区在内的全部证据被证明是系统发育重建的可靠方法。Augochlorini 多样化发生在新热带地区的高地,特别是巴西高原。在我们的分析中恢复了向亚马逊流域、中美洲和北美洲的多次扩散,并返回大西洋特有地区。包括形态分区在内的全部证据被证明是系统发育重建的可靠方法。Augochlorini 多样化发生在新热带地区的高地,特别是巴西高原。在我们的分析中恢复了向亚马逊流域、中美洲和北美洲的多次扩散,并返回大西洋特有地区。包括形态分区在内的全部证据被证明是系统发育重建的可靠方法。
