Archaeognatha (Machilida plus †Monura), with ~450 extant species worldwide, represent a key lineage for the understanding of insect evolution. In a recently published phylogenetic analysis on Archaeognatha, based on a total‐evidence approach, a Machilidae key fossil (Gigamachilis triassicus) from the Middle Triassic Lagerstätte of Monte San Giorgio and a representative of †Monura (Dasyleptus triassicus) from the same fossiliferous site, were not considered. In the present study, the phylogenetic analyses performed by Zhang et al. (2018) using maximum parsimony and Bayesian inference were repeated including these two key taxa; in addition, Tricholepidion gertschi and Lepisma saccharina were included as representatives of Zygentoma. In the total‐evidence Bayesian analysis, †Monura was found to be paraphyletic, whereas in the maximum parsimony analysis, performed only on morphological characters, they were monophyletic. Moreover, the attribution of G. triassicus to Machilidae is now confirmed by these analyses, indicating that members of the extant group of Machilidae were already present in the Middle Triassic, at least ~100 Myr before the previous estimate.

用四种新的白垩纪猪鬃进行系统发育分析的评论揭示了Meinertellidae 古颌和冈瓦纳起源的相互关系

Archaeognatha（Machilida 加 †Monura）在全世界拥有约 450 种现存物种，代表了了解昆虫进化的关键谱系。在最近发表的关于 Archaeognatha 的系统发育分析中，基于全证据方法，来自 Monte San Giorgio 的中三叠世 Lagerstätte 的 Machilidae 关键化石 (Gigamachilis triassicus) 和来自同一化石地点的 †Monura (Dasyleptus triassicus) 的代表，没有考虑。在本研究中，Zhang 等人进行的系统发育分析。(2018) 重复使用最大简约和贝叶斯推理，包括这两个关键分类群；此外，Tricholepidion gertschi 和 Lepisma saccharina 也被列为 Zygentoma 的代表。在全证据贝叶斯分析中，†Monura 被发现是并系的，而在最大简约分析中，仅对形态特征进行分析，它们是单系的。此外，现在这些分析证实了 G. triassicus 对 Machilidae 的归属，表明现存 Machilidae 组的成员已经存在于中三叠世，至少比之前的估计早约 100 Myr。
