Remarks: Bradley (1971: 25) designated a lectotype of E. holdenella from two specimens in Stainton’s collection in NHMUK, collected from Surrey. According to Traugott-Olsen (1974: 259), the original description of E. holdenella Stainton (1854: 252) was not based on either of these specimens, so Bradley’s lectotype designation is invalid. The species description, however, was based on only one specimen, so it is the holotype. Pelham-Clinton (1986) interpreted the type locality from the original label. All these specimens are conspecific (Traugott-Olsen 1974: 259). Records from Crimea reported by Budashkin & Sinev (1991) are referable to E. vulturna Kaila, 2015 .
