Four new species of oak gallwasps of the genus Dryocosmus: D. pentagonalis, D. triangularis, D. carlesiae, and D. testisimilis are described from Taiwan. They induce galls on one species of Castanopsis and one species of Lithocarpus (Fagaceae). Data on the diagnosis, distribution, and biology of the four new species is given. A key for Dryocosmus species identification of Taiwan is provided. Final comments discuss the polyphyletic nature of the Dryocosmus genus, emphasizing the urgent need for its revision.
