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.
