Remarks. We did not examine the holotype of this species and recognized it from the description of Herting (1968). It is similar to E. magna (Baranov) , but differs in having reddish-yellow palpi, wing yellow at base and in anterior portion, abdominal tergites covered with densely yellowish-gray or grayish-white pruinosity, without dark brown markings on tergite 3.
