Abstract
Asian genera and species of the tribe Dimerini from Asia are revised. Two new species of the nominotypical subgenus of the genus Octomicrus, O. (O.) enkaizanus from Japan, and O. (O.) kusakabei from Myanmar are described. A new genus, Microctomicrus is defined with a description of the type species, M. idrisi sp. nov. from Malaysia. The genus Tuberoplectus is recorded for the first time from Asia and a new species, T. cucphuongensis from Vietnam is described. Type materials of the other species preserved in MNHM (Paris) were revised New distributional records of O. (Octomicrus) longulus longulus from N Vietnam and O. (O.) fauvelijavanus from Java are added.
