小翅目化石是一个绝灭目,分布于德国(C2)和捷克、中亚、俄罗斯、美国(P),但在中国从来未曾发现过这个目的化石.2000年,笔者等在中国陕西铜川地区中三叠统铜川组下段上部灰绿色泥页岩中首次采到了小翅目昆虫化石.根据世界历史的参考文献,小翅目化石被发现的很少,已知报道的共有3科10属.此次所发现的有1新属和1新种Triasomiomopteris oblongata gen.et sp.nov..属种不多,但很珍贵,有一定的重要意叉,首先填补了中国小翅目化石这个领域的空白,也填补了世界中三叠世这个时代的空白,同时也打破了小翅目昆虫化石仅产于古生代晚期的说法,从而对于研究小翅目昆虫化石从二叠纪到中生代早期演化关系有一定的参考价值.

The Miomoptera is a small extinct fossil order, distributed in the Germany (C2), Czech, Middle Asia, Russia and American(P), but it had not been discovered in China. In 2000, the authors found a new genus with a new species, collected from the Midtriassic, grayish-green mudstone and shale of the Upper part of the Lower Member, Midtriassic Tongchuan Formation (T2t) in Tongchuan region of Shaanxi Province, China. According to the historical references of this order Miomoptera, the discovered fossil in world is rare, and it has known only 3 families and 10 genera and are reported. The discovery of the new fossil Triasomiomopteris oblongata gen. et sp. nov fills in the gap in the field of China and of the Midtriassic Miomoptera in the world, and has certain important reference value for the evolution of Miomoptera from the Late Paleozoic to Early Mesozoic eras.
