摘　　要：对中国中侏罗世九龙山组脉翅目昆虫化石的翅斑多样性进行了研究。共观察标本3 040件,所有标本皆产自内蒙古自治区赤峰市宁城县道虎沟地区。通过比较和总结共发现翅斑类型7型12类,各种翅斑类型差异明显。推测中侏罗世脉翅目化石翅斑的多样性与侏罗纪时期昆虫对特异环境的适应性和对天敌的防御机制密切相关。This paper summarizes the diversity of wing markings among Neuroptera from the Middle Jurassic Jiulongshan Formation in Daohugou Village, Ningcheng County, Inner Mongolia, China. Based on our studies of three thousand and forty specimens, we found twelve distinct types of wing markings in seven classes. We propose that the diversity of wing markings is closely related to the adaptability to the specific environment and the defense mechanism against predators during the Middle Jurassic.
