Material examined. China, Inner Mongolia: 1 ♀, Dong Ujimqin Qi, Wulagai , 22.VIII.1971, Y.-S. Shi leg. ( IZCAS) . Xinjiang: 1 ♂, Jitai, Shuiding , 460–480 m, 12.VII.1957, C.-P. Hong leg. ( IZCAS) . Xizang (= Tibet): 1 ♂, Milin, Songlinkou , 3760 m, 6.VIII.2015, H.-B. Liang leg. ( IZCAS) . Germany: 1 ♂, Bayer, Wald au Teisnach , 22.VII.1954, [no collector], ( ZMHB; det. J. Ziegler) ; 1 ♂, 1 ♀, Baden-Württemberg, Willingen , 7.VII.1997, H.-P. Tschorsnig leg. ( SMNS; det. H.-P. Tschorsnig) .

Distribution. China (Inner Mongolia, Xinjiang, Xizang), Europe (northwards to England and Germany, Transcaucasus).

Hosts. Coleoptera , Scarabaeidae ( Phyllopertha horticola ) (Ziegler & Tschorsnig 2016: 346).

Remarks. We have examined identified specimens from Europe and confirm that our specimens are conspecific with these. This species appears to be similar to E. acuta (Portschinsky) , but differs in having longer prementum, 3 presutural and 3 postsutural dorsocentral setae, wing cell r 4+5 closed, with a petiole, wing not brownclouded around crossveins r-m and dM-Cu.
