We describe four new ambrosia beetle species of the tribe Xyleborini, Cyclorhipidion beaveri Lin & Smith sp. nov., Cyclorhipidion cognatoi Lin & Smith sp. nov., Cyclorhipidion hsuae Lin & Smith sp. nov., and Cyclorhipidion wui Lin & Smith sp. nov., which complete their lifecycle on the host plant Castanopsis cuspidata (Hemsl.) (Fagaceae). Five newly recorded species, Anisandrus ursulus (Eggers, 1923), Arixyleborus minor (Eggers, 1940), Coptodryas mus (Eggers, 1930), Cyclorhipidion japonicum (Nobuchi, 1981), and Xyleborinus octiesdentatus (Murayama, 1931) are reported in Taiwan for the first time. We provide brief diagnoses, photographic images and biological information for each species in Taiwan.
