Reanalysis of the apoid wasp phylogeny with additional taxa and sequence data confirms the placement of Ammoplanidae as sister to bees

Apoid wasps and bees (Apoidea) are an ecologically and morphologically diverse group of aculeate Hymenoptera (ants, bees, and wasps). During the last decades, significant progress has been made in illuminating the phylogenetic relationships of the major Apoidea lineages. However, some uncertainties have remained. In this study, we present results from re-investigating the phylogeny of Apoidea by including genome skimming data of key taxa that were missing in previous investigations: a representative of Entomosericini (tribe of the former Pemphredoninae) and a representative of Eremiaspheciinae (subfamily of the former \"Crabronidae\"). We additionally skimmed the genomes of two Heterogyna species (Heterogynaidae). Our results from applying concatenation and coalescence-based phylogenetic approaches confirm the previously suggested sister group relationship of Ammoplanidae and bees. They also corroborate most taxonomic changes published in 2018 granting eight lineages of the former family ...类蜂总科（Apoidea）是针尾膜翅目（aculeate Hymenoptera，涵盖蚁类、蜂类与胡蜂）中一类在生态学与形态学上兼具高度多样性的类群。近数十年来，学界在阐明类蜂总科主要演化支系的系统发育关系方面已取得显著进展，但仍存在部分未解决的争议与不确定性。本研究通过纳入此前研究中缺失的关键类群的基因组浅层测序（genome skimming）数据，重新解析类蜂总科的系统发育关系，所纳入的关键类群包括：原方头泥蜂亚科（Pemphredoninae）下Entomosericini族的代表物种，以及原方头泥蜂科（Crabronidae）下Eremiaspheciinae亚科的代表物种。此外，本研究还对两种异泥蜂科（Heterogynaidae）物种进行了基因组浅层测序。本研究采用联配拼接法（concatenation）与基于溯祖理论的系统发育分析方法，所得结果证实了此前提出的泥蜂科（Ammoplanidae）与蜜蜂互为姊妹群的系统发育关系，同时也验证了2018年发布的多数分类学修订方案——该方案将原科划分为八个支系……
