Description. This new genus resembles Omphalodes in nutlet shape and size, from which it can be distinguished by the ornamentation of the margin of the nutlet, which abruptly changes towards the aperture from hairy-spiny to wrinkled and nearly smooth resulting in two distinctive parts. In addition, the nutlet scar is found apically and the margin is completely hollow by an extensive air chamber. An additional key character to distinguish this new genus is the presence of a ring-like equatorial aperture on the pollen grains, that is absent in the rest of species of Omphalodes .

Etymology. Nihon is the name of Japan in Japanese as written in Latin alphabet.
