Review of the genus Microperus Wood, 1980 (Coleoptera, Curculionidae, Scolytinae) of Taiwan with the description of two newly recorded species and the first description of males of six species

The Microperus ambrosia beetle fauna of Taiwan is reviewed. Microperus alpha (Beeson, 1929), M. kadoyamaensis (Murayama, 1934), M. kirishimanus (Murayama, 1955), M. perparvus (Sampson, 1922), M. quercicola (Eggers, 1926) have all been previously recorded from Taiwan. Microperus bucolicus Sittichaya, Smith & Beaver, 2021 and M. latesalebrinus Smith, Beaver & Cognato, 2020 are new country records for Taiwan. Of which, the males of M. alpha, M. bucolicus, M. kadoyamaensis, M. latesalebrinus, M. perparvus, and M. quercicola are described for the first time. In this study, we document a likely occurrence of mycocleptism by M. bucolicus. Diagnostic characters, biological data and a key to species in Taiwan are provided.
