Abstract: This study describes two new species of the lace bug genus Omoplax Horváth, 1912 (Hemiptera: Heteroptera: Tingidae) from Mukojima Island, the Ogasawara Islands, Japan, under the names O. karubei sp. nov. and O. mukojimensis sp. nov. These new species differ from the other species of Omoplax mainly in the shape of the pronotum and hemelytron. In all, five species belonging to two endemic genera are recognized from the Ogasawara Islands: Acanthomoplax tomokunii Souma & Kamitani, 2021, Omoplax desecta (Horváth, 1912), O. karubei sp. nov., O. majorcarinae Guilbert, 2001, and O. mukojimensis sp. nov. Additionally, several new records of tingid taxa endemic to these islands are provided: Acanthomoplax tomokunii Souma & Kamitani, 2021 from Ototojima Island, and Omoplax desecta (Horváth, 1912) from the Mukojima Group, and Meijima, Mukohjima and Nakoudojima islands. An updated key to the species is presented to facilitate the identification of Ogasawaran lace bugs.
