Trogiomorpha is the most ancient group of the Psocodea. In the over 100-year research history of Psocodea fossil, a total of 7 families, 41 genera, 67 species of Trogiomorpha fossils have been recorded. This paper reviewed the progress of Trogiomorpha fossil research worldwide, provided a checklist of all described fossil taxa of Trogiomorpha, summarized their stratigraphic distribution as well as geological ages. The unsolved problems of this group and prospects for the future were proposed.
