本文记述了一新种（短翅异翅蝗Alienopterus brachyelytrus Bai，Beutel，Klass，Wipfler et Zhang gen. et sp. nov.）一个新的订单和家庭的描述，基于一个单一的男性嵌入在白垩纪缅甸琥珀（约。99Ma）。不寻常的特征是缩短的前翼与发育完全、可操作的后翼相结合，类似于Dermaptera，以及专门的附着垫，否则只在蝠鲼（跟行者）中发现。一个分支系统学分析表明，一个位置作为姐妹Mantodea，支持profemoral刷和其他字符。男性生殖器在两组中表现出相同的模式。特殊的特征是不寻常的飞行器，适应于在叶子上运动的附着结构，以及适合捕捉小猎物的密集的profemoral刚毛。匕首翼龙显然能够飞行，可能是灌木丛或树木中小型节肢动物的捕食者。一个令人印象深刻的辐射Mantodea开始在类似的栖息地至少35Ma后，在新生代早期。相比之下，匕首翼龙在蟑螂和螳螂的过渡区是一个进化的死胡同。(C)2016年国际冈瓦纳研究协会。Elsevier B.V.出版，保留所有权利。
A new insect species (dagger Alienopterus brachyelytrus Bai, Beutel, Klass, Wipfler et Zhang gen. et sp. nov.) of a new order and family is described, based on a single male embedded in Cretaceous Burmese amber (ca. 99 Ma). Unusual characters are shortened forewings combined with fully developed, operational hindwings, similar as in Dermaptera, and specialized attachment pads otherwise only found in mantophasmatodeans (heelwalkers). A cladistic analysis suggests a placement as sister to Mantodea, supported by a profemoral brush and other characters. The male genitalia show the same pattern in both groups. Specialized features are the unusual flight apparatus, attachment structures adapted for locomotion on leaves, and a dense profemoral setation suitable for catching small prey. dagger Alienopterus was apparently able to fly and likely a predator of small arthropods in bushes or trees. An impressive radiation of Mantodea started in similar habitats at least 35Ma later in the early Cenozoic. In contrast, dagger Alienopterus was an evolutionary dead end in the roach-mantis transition zone. (C) 2016 International Association for Gondwana Research. Published by Elsevier B.V.
