New antlions (Insecta: Neuroptera: Myrmeleontidae) from the mid-Cretaceous of Myanmar and their phylogenetic implications

Myrmeleontidae (antlions) is the most species-rich family of the holometabolous order Neuroptera. Evolutionary history of this diverse lacewing family remains largely unexplored. Here we report on three new genera and four new species of antlions from the mid-Cretaceous amber of Myanmar, namely Allopteroneura burmana Lu, Zhang & Liu gen. et sp. nov., Phylloleon elegans Lu, Wang & Liu gen. et sp. nov., Phylloleon stangei Lu, Ohl & Liu gen. et sp. nov. and Nanoleon wangae Hu, Lu & Liu gen. et sp. nov. A phylogenetic analysis of the Burmese amber antlions is performed based on morphological characters. The result shows that the antlion species presently described belong to different major clades across the phylogenetic tree, suggesting a diverse palaeofauna of this family from the mid-Cretaceous of Myanmar. The phylogenetic status of the extinct subfamily Araripeneurinae is also discussed. http://zoobank.org/urn:lsid:zoobank.org:pub:90D26B8B-1A59-465B-A530-0C0662D85E72蚁蛉科（Myrmeleontidae）是全变态类脉翅目（Neuroptera）中物种多样性最高的科。目前，这一多样化的蚁蛉类群的演化历史仍未得到充分探索。本文报道了产自缅甸中白垩纪琥珀中的3个新属及4个蚁蛉新种，分别为Allopteroneura burmana Lu, Zhang & Liu gen. et sp. nov.、Phylloleon elegans Lu, Wang & Liu gen. et sp. nov.、Phylloleon stangei Lu, Ohl & Liu gen. et sp. nov.以及Nanoleon wangae Hu, Lu & Liu gen. et sp. nov.。研究基于形态特征对缅甸琥珀中的蚁蛉类群开展了系统发育分析，结果显示，本次记述的蚁蛉物种分属于系统发育树上的多个不同主要演化支，表明缅甸中白垩纪时期该科的古动物区系已具备高度多样性。此外，本文还讨论了已灭绝的阿拉里平蚁蛉亚科（Araripeneurinae）的系统发育地位。http://zoobank.org/urn:lsid:zoobank.org:pub:90D26B8B-1A59-465B-A530-0C0662D85E72
