Abstract: This paper deals with a taxonomic study of Coptacra Stål, 1873 from China, with a description of a new species Coptacra xiai sp. nov. The new species is similar to C. yunnanensis Zhang et Yin, 2002, but the frontal ridge contracted under median ocellus; vertical diameter of eye 2.2 times its horizontal diameter; median vein area of tegmen wider than cubital area; upper ovipositor valves narrow, long and smooth. A key to the known species of the genus Coptacra from China is given. The type specimens are deposited in the Museum of Hebei University (MHU), China.
