Distribution. China (Inner Mongolia, Xinjiang), Europe (northwards to Denmark and Finland), Kyrgyzstan, Transcaucasus.

Hosts. Coleoptera Scarabaeidae : Amphimallon solstitiale (Linnaeus) (Ziegler & Tschorsnig 2016: 346) .

Remarks. We identified this species by comparison with European specimens identified by H.-P. Tschorsnig (SMNS) and J. Ziegler (ZMHB). It is similar to E. picta (Meigen) , but differs in having narrower frons, shorter aristal hairs, dark postpronotum and tergites 3 and 4 each with 2 to 3 pairs of median discal setae.
