Abstract
The family Metopidiotrichidae and the genus Metopidiothrix Attems, 1907 are formally new to the fauna of Taiwan, due to the discovery of Metopidiothrix taiwanensis sp. nov. The fauna of Chordeumatida of Taiwan is reviewed and keyed, at present containing 13 unquestioned species from three genera and three families. Three further species, one genus and one family are dubious either as taxa or as elements of the Taiwanese fauna, or both. Palaearctic elements, such as Diplomarag-nidae and Niponiosomatidae, appear to strongly dominate over austral/tropical ones (Metopidiotrichidae).
