Revision of the genera Thanmoia Ramme, 1941 and Paratoacris Li & Jin, 1984 (Orthoptera: Acrididae: Oxyinae), with a proposal of a new generic synonym and a new combination

The genera Thanmoia Ramme, 1941 and Paratoacris Li & Jin, 1984 are revised based on the examination of type specimens of all species. As a result, the genus Paratoacris is synonymized with Thanmoia and a new combination is proposed: Thanmoia reticulipennis (Li & Jin, 1984) comb. nov. All five species are re-described and illustrated. A key to species is provided. Thanmoia gustavi Ramme, 1941 is recorded for the first time from China. Distribution patterns of species across Vietnam and China and the phylogenetic position of the genus Thanmoia are briefly discussed.
