A new species, Orsodacne yunnanicus Legalov, sp. nov. from Yunnan Province (China) is described and illustrated. The new species is similar to Orsodacne cerasi (Linnaeus, 1758) but differs from it in the coarse punctate pronotum, densely punctate head covered with appressed setae, and the endophalus sac with many minute sclerites. A distribution map for Orsodacne-species from Asia is given.
