Parapanteles Ashmead (Braconidae: Microgastrinae) is a medium-sized genus of microgastrine wasps that was erected over a century ago and lacks a unique synapomorphic character, and its monophyly has not been tested by any means. Parapanteles usually are parasitoids of large, unconcealed caterpillars (macrolepidoptera) and have been reared from an unusually large diversity of hosts for a relatively small microgastrine genus. We used Cytochrome Oxidase I sequences (“DNA barcodes”) available for Parapanteles and other microgastrines to sample the generic diversity of described and undescribed species currently placed in Parapanteles, and then sequenced four additional genes for this subsample (wingless, elongation factor 1-alpha, ribosomal subunit 28s, and NADH dehydrogenase subunit 1). We constructed individual gene trees and concatenated Bayesian and maximum-likelihood phylogenies for this 5-gene subsample. In these phylogenies, most Parapanteles species formed a monophyletic clade within another genus, Dolichogenidea, while the remaining Parapanteles species were recovered polyphyletically within several other genera. The latter likely represent misidentified members of other morphologically similar genera. Species in the monophyletic clade containing most Parapanteles parasitized caterpillars from only five families - Erebidae (Arctiinae), Geometridae, Saturniidae, Notodontidae, and Crambidae. We do not make any formal taxonomic decisions here because we were not able to include representatives of type species for Parapanteles or other relevant genera, and because we feel such decisions should be reserved until a comprehensive morphological analysis of the boundaries of these genera is accomplished.

由五个基因组成的分子系统发育研究表明,伞形目亚目(Phypanteles Ashmead)(膜翅目:Braconidae)具有当前的多系统性。

帕拉潘特莱斯·阿什米德Brapanidaes:Microgastrinae)是一种中型的微胃泌机黄蜂属,建于一个多世纪前,缺乏独特的共形特征,并且其单生没有经过任何测试。副pan通常是大型的,未隐匿的毛毛虫(大鳞翅目)的寄生虫,并且是从种类繁多的宿主中培育出来的,其种类相对较小。我们使用了可用于动物和其他微胃动物的细胞色素氧化酶I序列(“ DNA条形码”),对目前放置在腹足动物中的已描述和未描述物种的通用多样性进行了采样,然后对该子样本测序了四个其他基因(无翅,伸长因子1-α,核糖体亚基28sNADH脱氢酶亚基1)。我们为此5个基因子样本构建了单独的基因树,并连接了贝叶斯和最大似然系统发育。在这些系统发育,大多数Parapanteles物种形成的另一个属,内单系群Dolichogenidea,而其余Parapanteles物种被其他几个属内polyphyletically恢复。后者可能代表其他形态相似属的错误识别成员。单系进化枝中包含大多数副颚的物种仅五个科的寄生虫毛虫-E科(Etibidae(Arctiinae),Geometridae,Saturniidae,Notodontidae和Crambidae)。我们在这里没有做出任何正式的分类学决策,因为我们无法包括百日草或其他相关属的类型物种的代表,并且因为我们认为应该保留这些决策,直到对这些属的边界进行全面的形态学分析为止。
