描述了中国下白垩纪的四种巨型蜻蜓幼虫。由于幼虫的翅鞘上保存有翅气管脉，它们可以被确定为中生代已灭绝的叶蝉科的第一批幼虫。它们是最终或倒数第二的雄性和雌性标本，以及更年轻的幼虫。雌性幼虫有很长的产卵鞘。这些幼虫有一个异翅目的肛门金字塔和一个非常特殊的勺形唇膜，有一个非常窄的前肢和巨大的触须，上面有许多牙齿，这表明Aeschnidiidae可能与Cavilabiata异翅目相近。讨论了其他正式归属于Aeschnidiidae科的幼虫的位置，即Nothomacromia sensibilis (Carle and Wighton, 1990), Sona nectes Pritykina, 1986，以及Hemeroscopus baissicus Pritykina， 1977。尽管它们在肛门金字塔上有一些相似之处，但在唇形和雌性产卵器上，它们与真正的中国幼虫有很大的不同。
Four giant dragonfly larvae are described from the Lower Cretaceous of China. Owing to the preservation of wing tracheal venation on the larval wing sheaths, they can be identified as the first undoubted larvae of the extinct Mesozoic family Aeschnidiidae. They are ultimate or penultimate male and female specimens, and a younger larva. The female larva has a very long ovipositor sheath. These larvae have an anisopteran anal pyramid and a very particular spoon‐shaped labial mask, with a very narrow prementum and large palps with numerous teeth, suggesting possible affinities of the Aeschnidiidae with the Anisoptera Cavilabiata. The positions of other larvae formally attributed to the Aeschnidiidae are discussed, i.e. Nothomacromia sensibilis (Carle and Wighton, 1990), Sona nectes Pritykina, 1986, and the alleged larvae of Hemeroscopus baissicus Pritykina, 1977. They differ greatly from the true Chinese larval Aeschnidiidae, in the labial mask and female ovipositor, even if they show some similarities in the anal pyramid.
