| Outline of Final Research Achievements |
Polyneoptera, which was directly derived from the initial explosive radiation of insects, is the most significant group in understanding them, simultaneously Polyneoptera is a most difficult group to figure out the evolution. We have conducted a comparative embryological study of Polyneoptera, and we clarified the embryogeneses of Zoraptera, a primitive mantodean, Isoptera, Blattaria, all 9 families of Dermaptera, and all 9 families of plecopteran Arctoperlaria. Based on these results, 1) we proposed two embryological autapomorphies of Polyneoptera, on the monophyly of which a doubt has been cast, 2) we strongly suggested the affinity of Zoraptera, Phasmatodea and Embioptera formulated as “Zoraptera + (Phasmatodea + Embioptera)”, and 3) we proposed a new phylogenetic system of Dictyoptera “Mantodea + (Blaberoidea + (Blattodean + Isoptera))”.
