The present study is based on oribatid mite materials (Acari, Oribatida) collected from Taiwan in 2009–2010. A list of identified taxa, including 34 species from 30 genera and 21 families, is presented; of these, the subspecies Tectocepheus velatus sarekensis, the species Suctobelbella (Flagrosuctobelba) cf. elegantula, Paralamellobates misella, Protoribates paracapucinus, Perscheloribates nodosus and Scheloribates (Bischeloribates) dalawaeus, the subgenera Uracrobates (Parauracrobates) and Scheloribates (Bischeloribates), and the genera Scapheremaeus and Brassiella are recorded in the fauna of Taiwan for the first time. The species Camisia hamulifera and Fissicepheus defectus are recorded in the Oriental region for the first time. Two new species belonging to the genera Galumna (Galumnidae) and Uracrobates (Mochlozetidae) are described. Galumna (Galumna) tsengi sp. nov. differs from G. (G.) makilingensis Ermilov, Corpuz-Raros & Tolstikov, 2014 by the clavate heads of the bothridial setae, slightly dilated porose areas Aa in posterolateral parts, not boomerang shaped, and by the erect interlamellar setae, which are shorter than the lamellar setae. Uracrobates (Parauracrobates) newtaipeiensis sp. nov. differs from U. (P.) truncatus Ermilov & Martens, 2015 by the absence of well-developed lateral teeth on the lamellar cusps, foveolate notogaster and anogenital region and the medium length of the anal and adanal setae.
