This paper reports two new species of Coptacra Stl, i.e. C. taiwanensis sp. nov. and C. yunnanensis sp. nov.Type specimens are deposited in the Museum of Hebei University. Coptacra taiwanensis sp. nov. (Figs. 1 6 )This new species is similar to C. tonkinensis Willemse, but differs from the latter in: 1) anterior transverse sulcus of pronotum deeply cut into the median keel; 2) length of forewing 3 75(♂)or 3 82 (♀) times that of pronotum; 3) apex of forewing more round and a little obliquely truncate; 4) length of last ramification of Rs equal to width of forewing across ramified place; 5) prozona of pronotum 0 85 (♂) or 0 88 (♀) times metazoan in length; 6) upper valves of ovipositor with obvious larger teeth, its apical part curved weakly. Length of body:♂22 1?mm,♀32 2?mm.Length of pronotum: ♂5 1?mm, ♀7 3?mm.Length of elytra:♂ 18 2?mm,♀28 5?mm.Length of hind femur:♂ 13 4?mm, ♀18 2?mm. Holotype ♂, paratype 1 ♀, Taiwan Pingdong (Ebijian) (21°54′N, 120°50′E ), 110?m,29 July 2000, collected by REN Guo Dong. Coptacra yunnanensis sp. nov. (Figs. 7 10 )This new species is similar to C. tonkinensis Willemse, but differs from the latter in: 1) anterior transverse sulcus of pronotum deeply cut into the median keel; 2) length of last ramification of Rs 0 8 time of width of forewing across ramified place; 3) length of prozona of pronotum 0 75 time that of metazoan; 4) upper valves of ovipositor with smaller teeth, its apical part curved distinctly. This new species is also similar to C. taiwanensis sp.nov., but differs from the latter in :1) length of forewing 4 times that of pronotum; 2) apex of forewing with a distinct oblique truncation; 3) upper valves of ovipositor with smaller teeth, its apical part curved distinctly. ♀\ Length of body 32 1?mm.Length of pronotum 7 3?mm.Length of elytra 30 4?mm.Length of hind femur 19 1?mm. Holotype ♀, Yunnan Jinghong (21°27′N,100°25′E),alt. 2?196 8?m. 29 Aug. 2000, collected by ZHU Ming Sheng.
