摘　　要：记述龙蝎蛉新科Drakonochoristidae fam. nov.和1新亚科及其2新属、种和1个老亚科。2新属种的化石标本采自中国陕西铜川中三叠统铜川组下段上部的灰绿色泥岩和页岩。新科性质及其分类位置在文中进行讨论。新科的建立填补这个类群在中国的空白,同时对于小蝎蛉科Nannochoristidae和二叠蝎蛉科Permochoristidae的演化关系的研究有一定的意义。这些新属、种系陕西昆虫群(陕西生物群的一个类别)铜川昆虫组合的新成员。铜川组的时代相当于欧洲拉丁尼期(Ladinian Stage)。A new family Drakonochoristidae fam. nov. is described to include a new subfamily Drakonochoristinae and the subfamily Pseudoannochoristinae Novokshonov,1994. The new subfamily with two new genera and species were collected from the Middle Triassic Tongchuan Formation of the Tongchuan Region,Shaanxi Province,China. The characters of the new family and its taxonomic position are discussed. The discovery of the new family has yielded certain reference values,especially for the study on the evolutionary relationship between the Permochoristidae and Nannochoristidae.
