描述了采自内蒙古道虎沟中侏罗世的扁蜂总科Xyelydidae（胡蜂目=膜翅目）的3个新种：小叶蜂Ferganolydascylla sp. nov.，F. charybdis sp. nov.和F. chungkuei sp. nov.新发现的材料表明，以前被认为是一个形态上普通的结网叶蜂类群的Ferganolyda，实际上是一个非常不寻常的昆虫分类群。它的特征是，特别是在雄性中，有一个巨大的头（大约是整个体长的一半宽）和不寻常的触角变形。解释不寻常的头部和触角的功能是有趣的，但尚未解决。
Three new species, attributed to the extinct family Xyelydidae of the Pamphilioidea ( Order Vespida = Hymenoptera), are described from the Middle Jurassic of Daohugou, Inner Mongolia, China: Ferganolyda scylla sp. nov., F. charybdis sp. nov. and F. chungkuei sp. nov. The new material demonstrates that the genus Ferganolyda, which was previously considered to be a morphologically ordinary group of web-spinning sawflies, is in fact a highly unusual insect taxon. It is characterised, particularly in the male sex, by a huge head (about half as wide as the entire body length) and unusual modification of the antennae. Interpretation of the function of the unusual head and antennae is intriguing but unresolved.
