| Outline of Final Research Achievements |
Trichadenotecnum species of Southeast Asia were revised taxonomically. During the project period, a total of nine new species were described and a genus, Cryptopsocus from China, was synonymized with Trichadenotecnum.
World-based phylogeny of Trichadenotecnum was estimated. Most species groups recognized morphologically were identified as monophyletic group. In contrast, extensive morphological convergences/reversals were detected in a few species group, which caused inappropriate species-group classification. Dating and biogeographical analyses suggested that the tans-continental dispersal via Bering Strait during the Tertiary period and reduction of distributional area during the last gracious period affected strongly in forming the present distributional pattern of Trichadenotecnum.
