Rogadinae are a cosmopolitan, species‐rich braconid wasp subfamily whose species are endoparasitoids that attack larvae of a number of lepidopteran families. Members of this subfamily are characterized by pupating within the mummified host larval skin. The subfamily contains six tribes whose relationships have only been partially clarified: Aleiodini, Betylobraconini, Clinocentrini, Rogadini, Stiropiini and Yeliconini. The limits and composition of the closely related subfamilies to the Rogadinae, Hormiinae and Lysiterminae, also remain unclear. Here, we generated ultraconserved element data to reconstruct an almost fully resolved phylogeny for the members of Rogadinae and related subfamilies. Based on our best estimate of phylogeny, we confirm the monophyly of Rogadinae including Betylobraconini, synonymize Xenolobus Fahringer and Bequartia Cameron within the species‐rich genus Aleiodes Wesmael (syn.n.) based on DNA, and synonymize Promesocentrus van Achterberg with Pilichremylus Belokobylskij (syn.n.) based on morphology. We also consistently recovered Hormiinae and Lysiterminae as not reciprocally monophyletic, and thus propose to unite their members under Hormiinae. The ancestral host preference for Rogadinae was probably attacking concealed lepidopteran larvae, with the occurrence of at least two main subsequent transitions to attack both concealed and exposed hosts, one within Rogadini and a second within Aleiodini. We highlight the importance of natural history collections as a source for conducting genomic‐based studies using techniques that allow to obtain a substantial amount of data from considerably old preserved insect specimens.

鳞翅目内寄生蜂亚科 Rogadinae(膜翅目:蜂科)和相关亚科的系统基因组学

Rogadinae 是一个世界性的、物种丰富的 Braconid 黄蜂亚科,其物种是攻击许多鳞翅目科的幼虫的内寄生物。该亚科成员的特征是在木乃伊化的宿主幼虫皮肤内化蛹。该亚科包含六个部落,其关系仅得到部分澄清:Aleiodini、Betylobraconini、Clinocentrini、Rogadini、Stiropiini 和 Yeliconini。与 Rogadinae、Hormiinae 和 Lysiterminae 密切相关的亚科的范围和组成也不清楚。在这里,我们生成了超保守元素数据,以重建 Rogadinae 和相关亚科成员的几乎完全解析的系统发育。根据我们对系统发育的最佳估计,我们确认了 Rogadinae 的单系性,包括 Betylobraconini,根据 DNA 将 Xenolobus Fahringer 和 Bequartia Cameron 同义于物种丰富的 Aleiodes Wesmael (syn.n.) 属中,并根据形态将 Promesocentrus van Achterberg 与 Pilichremylus Belokobylskij (syn.n.) 同义。我们还始终将 Hormiinae 和 Lysiterminae 恢复为不是相互单系的,因此建议将它们的成员统一在 Hormiinae 下。Rogadinae 的祖先宿主偏好可能是攻击隐蔽的鳞翅目幼虫,随后发生了至少两个主要的后续转变来攻击隐蔽和暴露的宿主,一个在 Rogadini 内,第二个在 Aleiodini 内。
