Abstract. The Gasteruptiidae are an easily recognised family of wasps whose larvae are considered predator-inquilines in the nests of solitary bees and wasps. There has been minimal molecular research on the family and as a result little understanding of the evolutionary relationships within the group. We present the first molecular phylogeny focused on Gasteruptiidae, generated using three molecular fragments (mitochondrial C01 and nuclear markers EF1-α and 28s) and estimate the divergence times of Evanioidea based on three secondary calibration points. The analyses included 142 specimens of Gasteruptiidae and 5 outgroup taxa from Aulacidae and Evaniidae. The monophyly of the Gasteruptiidae and its subfamilies Gasteruptiinae (Gasteruption) and Hyptiogastrinae (Hyptiogaster and Pseudofoenus) are confirmed. Our results indicate that Evanioidea diverged during the late Jurassic at 151.3 (171.99–136.15) Ma with Evaniidae during the early Cretaceous at 137.33 (140.86–133.67) Ma, and Gasteruptiidae during the Palaeocene at 60.23 (83.78–40.02) Ma. The crown age of Hyptiogastrinae was estimated to be during the mid-Eocene 40.72 (60.9–22.57) Ma and for Gasteruption during the early Eocene at 47.46 (64.7–31.75) Ma, which corresponded to their host divergence ages. We anticipate that more extensive taxon sampling combined with the use of phylogenomic data will help resolve low support within the Gasteruption clade.

gasteruptiid 黄蜂(膜翅目:Evanioidea)的系统发育和分歧估计揭示了与宿主的相关性

摘要。Gasteruptiidae 是一种很容易识别的黄蜂科,其幼虫被认为是独居蜜蜂和黄蜂巢中的捕食者。对该家族的分子研究很少,因此对群体内的进化关系知之甚少。我们展示了第一个专注于 Gasteruptiidae 的分子系统发育,使用三个分子片段(线粒体 C01 和核标记 EF1-α 和 28s)生成,并基于三个二级校准点估计 Evanioidea 的发散时间。分析包括 142 个 Gasteruptiidae 标本和来自 Aulacidae 和 Evaniidae 的 5 个外群分类群。确认了 Gasteruptiidae 及其亚科 Gasteruptiinae (Gasteruption) 和 Hyptiogastrinae (Hyptiogaster 和 Pseudofoenus) 的单系。我们的研究结果表明,晚侏罗世 151.3 (171.99–136.15) Ma 与早白垩世 137.33 (140.86–133.67) Ma 的 Evaniidae 和古新世 (60.23–80.28) Ma 的 Gasteruptiidae 分叉。Hyptiogastrinae 的冠年龄估计在中始新世 40.72 (60.9-22.57) Ma 和早始新世期间的 Gasteruption 47.46 (64.7-31.75) Ma,这对应于它们的寄主分化年龄。我们预计更广泛的分类单元采样结合系统发育数据的使用将有助于解决 Gasteruption 进化枝内的低支持问题。Hyptiogastrinae 的冠年龄估计在中始新世 40.72 (60.9-22.57) Ma 和早始新世期间的 Gasteruption 47.46 (64.7-31.75) Ma,这对应于它们的寄主分化年龄。我们预计更广泛的分类单元采样结合系统发育数据的使用将有助于解决 Gasteruption 进化枝内的低支持问题。Hyptiogastrinae 的冠年龄估计在中始新世 40.72 (60.9-22.57) Ma 和早始新世期间的 Gasteruption 47.46 (64.7-31.75) Ma,这对应于它们的寄主分化年龄。我们预计更广泛的分类单元采样结合系统发育数据的使用将有助于解决 Gasteruption 进化枝内的低支持问题。
