A new oribatid mite species of the genus Kunstidamaeus Miko, 2006 (Oribatida, Damaeidae) is described from Taiwan, based on adult and tritonymphal instar; Kunstidamaeus yilanensis sp. nov. differs from similar damaeid species by the long and flagellate interlamellar, exobothridial and some epimeral setae (3c, 4c, 4d), and the presence of prodorsal tubercles Da, Ba and La, prodorsal enantiophyses and ventrosejugal tubercles. Four Asian species, originally described as species of Epidamaeus Bulanova-Zachvatkina, 1957, are transferred to the genus Kunstidamaeus: K. fragilis (Enami & Fujikawa, 1989) comb. nov., K. parayunnanensis (Ermilov & Kaluz, 2013) comb. nov., K. verrucatus (Enami & Fujikawa, 1989) comb. nov., K. yunnanensis (Enami, Aoki & Hu, 1994) comb. nov.
