在两个新属中描述了三种新的结网虫物种（Embiodea），它们都保存在缅甸北部的上白垩纪琥珀中。 Henoclothoda simplex Cui 和 Engel，gen。等十一月，Gnethoda symma Cui 和 Engel，gen。等11 月，Gnethoda ancyla Cui 和 Engel，gen。等nov.，由于其简化的雄性终生而被归入 Clothodidae 科，其中骨片通常是对称的，第十块底骨是不分开的。 Gnethoda Cui 和 Engel，gen。 11 月，被分配到一个新的亚科，Gnethodinae Cui 和 Engel 亚科。 11 月，基于其简化的医疗系统，与所有其他 Clothoids 不同。然而，这一特征的极性需要在未来的研究中通过对目进行扩展的分支分析来澄清。此外，两种秘鲁的 Clothodinae 物种被转移到 Nonaia Engel 属，gen.十一月新的化石物种丰富了白垩纪琥珀中Embiodea的多样性，需要进一步探索以更好地解决我们对昆虫进化的理解。 (C) 2020 Elsevier Ltd. 保留所有权利。
Three new species of webspinners (Embiodea) are described in two new genera, all preserved in Upper Cretaceous amber from northern Myanmar. Henoclothoda simplex Cui and Engel, gen. et sp. nov., Gnethoda symmetrica Cui and Engel, gen. et sp. nov., and Gnethoda ancyla Cui and Engel, gen. et sp. nov., are described in the family Clothodidae owing to their simplified male terminalia, in which the sclerites are generally symmetrical and the tenth tergum is undivided. Genus Gnethoda Cui and Engel, gen. nov., is assigned to a new subfamily, Gnethodinae Cui and Engel, subfam. nov., based on its simplified medial system, unlike all other clothodids. However, the polarity of this character needs to be clarified by expanded cladistic analyses of the order in future studies. In addition, two Peruvian species of Clothodinae are transferred to the genus Nonaia Engel, gen. nov. The new fossil species enrich the diversity of Embiodea in Cretaceous amber and further exploration is needed to better resolve our understanding of evolution in this order of insects.
