摘　　要：截至目前,中国古昆虫学家已研究了分布于中国14省区的50件直翅目化石标本,发表新属38个,新种48个。通过图表提供了我国已发现的直翅目化石名录并介绍了其分布和年代。直翅目化石的研究对昆虫的起源、昆虫与植物的协同演化及古气候的演变等研究提供线索。中国已发现的直翅目化石主要分布于辽、冀、内蒙古三省区,其地质时代大部分为中生代。提出了在化石研究中存在的问题。To date, 50 Orthopteran fossils have been found from 14 provinces in China, among which 38 genera including 48 species were published. In this paper, a checklist table of described Chinese Orthopteran fossils, with their distribution and age, is provided. The study on fossil Orthoptera is of great importance for the further progress in the proper understanding of the origin of Orthoptera, the coevolution between insects and plants, the changes of paleoclimate, etc. Unfortunately, the research on Orthopteran fossils in China is still in rather chaotic state and badly needs revision. Chinese Orthopteran fossils are mainly found in Liaoning, Hebei and Inner Mongolia; and most of them are from Mesozoic.Whereas, the reason for all this imbalance in distribution is not quite clear now and still need further studying. Many of the previously recovered Orthopteran fossils from China were not complete and in most cases only fragment of wings or parts of body were preserved. Hence, initially established taxa that based on those fragmentary fossils are problematic. Another notable problem is the absence of a universally adopted authentic system for classification. Besides the alpha classification, studies on the coevolution between Orthoptera and plants, using fossil Orthoptera as pointer to changes of paleoclimate, etc. are all important and nearly unexplored, to which we should pay more attention in our future work.
