The species of the genus Reicheiodes Ganglbauer, 1891 from Taiwan are reviewed. The Taiwanese fauna consists of three species: Reicheiodes (Reichonippodes) kuankong sp. nov., R. (Reichonippodes) ursinus sp. nov., and R. (Reichonippodes) taiwanensis Bulirsch, 2018; the latter previously known in the female holotype only. All species are (re)described, diagnosed, their habitus and male genitalia are illustrated, and the body measurements are provided for the newly collected specimens of R. taiwanensis. Keys to all Taiwanese species, as well to all species of the subgenus Reichonippodes Dostal, 1993, are provided. DNA barcodes are provided for all three species and used to reconstruct the phylogenetic relationship of the species and to estimate their age. Both morphological and DNA data indicate that all three species are closely related and probably represent within-island radiation in the last 2.4 million years. All three species are allopatric, inhabiting the northern (R. kuankong), central (R. taiwanensis) and southern (R. ursinus) Taiwan. All specimens were sifted from the leaf litter of lowland to submontane (R. kuankong) or higher montane (R. taiwanensis and R. ursinus) broadleaf forests.
