Abstract:
The Ypsolophid genus Rhabdocosma Meyrick is reviewed. It comprises two known species: R.?aglaophanes Meyrick and R.?dolini Gershenson, and one new species from Japan, R.?nematopogonites Sohn, sp. nov. Photos of imagoes and male genitalia are provided for all three species of Rhadocosma. A close relationship between R.?dolini and the new species, and its significance in the biogeography and world species diversity of Rhabdocosma, are discussed.
