辽西义县组的两种黄蜂，中国，被描述并图解为Crephanogaster rara sp.11月和Tuphephialtites zherikhini gen.ET sp.11月在辽西地区膜翅目昆虫组合中，头翅目昆虫只占很小的比例，这表明义县组的时代可能是早白垩世，也可能是晚侏罗世。这是中国上中生界的首次发现。(C)2002爱思唯尔科学有限公司。保留所有权利。
Two wasps belonging to the family Ephialtitidae from the Yixian Formation of western Liaoning, China, are described and illustrated as Crephanogaster rara sp. nov. and Tuphephialtites zherikhini gen. et sp. nov. That ephialtitids occupy a very small proportion of the hymenopteran assemblage in western Liaoning suggests the age of the Yixian Formation to be Early Cretaceous or, possibly, as old as latest Jurassic. This is the first record of Ephialtitidae from the upper Mesozoic of China. (C) 2002 Elsevier Science Ltd. All rights reserved.
