对异翅亚目蜻蜓目Aeschnidioidea中Aeschnidiidae的化石进行了鉴定和描述，并对它们的系统发育关系和生物生态学特征进行了推断。以前在中国、蒙古和俄罗斯发现并被认为是细鳞虫科的细鳞虫，事实上与这一群无关。中国6属9种植物可合并为一种，即黑山山毛蕨Aeschnidium heishankowense。它是第一个来自东亚热河生物群的动物，与德国下提东阶的已知物种有关。最古老的化石地层的地质年代是有争议的;它可能是最晚的侏罗纪而不是早白垩世。
Undoubted fossil nymphs of the family Aeschnidiidae within the Aeschnidioidea of the Anisoptera, Odonata are identified and described and their phylogenetic relationship and bioecological characteristics are deduced. The nymphs discovered previously in China, Mongolia and Russia and considered to be aeschnidiids are, in fact, unrelated to this group. All nine Chinese species in six genera can be merged into one alone, Aeschnidium heishankowense. It is the first animal from the ‘Jehol biota’ of East Asia to be linked with the species known from the Lower Tithonian of Germany. The geological age of the oldest strata bearing the fossil nymphs is debatable; it could be latest Jurassic rather than Early Cretaceous.
