The tribe Acalyptini is redefined, distinguished from the tribe Derelomini and placed in the subfamily Curculioninae. Most genera classified in Derelomini from Asia are transferred to Acalyptini: Derelomorphus Marshall, Eudela Pascoe, Eudelodes Zimmerman, Meredolus Marshall, Nodocnemus Marshall and Tithene Pascoe. Thus, at least in the Malesia (Malay Peninsula to New Guinea), Pacific islands and also Australia, weevils associated with the flowers of palms belong not to Derelomini but to Acalyptini except for introduced species. The genera Orsophagus Roelofs and Imera Pascoe, which were synonymized with Acalyptus Schoenherr and Amorphoidea Motschulsky, respectively, are resurrected to the status of full genera. All the genera classified in Acalyptini are briefly reviewed and a key to them is provided. Japanese, Korean and Taiwanese species are treated taxonomically, and a total of 5 genera and 7 species are recognized including the following new species: Orsophagus subfasciatus (Japan, Taiwan and Thailand), Parimera flava (Japan), P. subflava (Taiwan) and Imera formosana (Taiwan). Amorphoidea gossyppi (Pierce) known from the Philippines is synonymous with A. lata, one of the famous pests of cotton in the Philippines. The genera Imera and Parimera are recorded in this area for the first time.
