Five species of Micropeplus are reported from Taiwan of which two are described as new. These are M. yushanensis and M. nitidipennis. Mictopeplus sinuatus Campbell is redescribed to include the previously unknown characters of the male. The two new species and M. sinuatus are illustrated with scanning electron photomicrographs and the aedeagi are illustrated with line drawings. Maps are presented showing the known distribution of all the species of Taiwan. Micropeplus sinuatus is transferred from the Staphylinoides group to the newly described sinuatus group. A revised key is presented to aid in the identification of all species of the family known from Taiwan.
