摘　　要：采自辽宁省凌源县大新房子村西部晚侏罗世地层中的一种鞘翅目化石,标本保存完好,其分类位置属于花蚤总科,接近于花蚤科和先花蚤科。标本保存了一些原始特征,为此,建立一新科——辽西花蚤科。迄今为止,晚侏罗世和早白垩世的花蚤类化石极为鲜见,文内描述的Liaoximordella hongi及相同层位的化石组合,对辽西地区中生代地层的划分和晚侏罗世花蚤类的演化均具有重要的意义。In the autumns of 1988 and 1989, some fossil insects were collected from the late Jurassic Yixian Formation (J_(3y)) of Daxinfangzi Village, Lingyuan County, western Liaoning Province, China, and a new familly Liaoximordellidae is here erected and described in this paper. The specimen obtained from the greyish-white tuffaceous shale is associated with some fish (Lycoptera), plant and molluscan fossils. The new familly is close to Praemordellidae Scegoleva-Barovskaja, 1929, but it may be distinguished from the latter by the fact that the insect body does not arch and that the head is prognathous, its hind-legs slender, tibiae long and abdomen with 6 segments.
