Diagnosis. Forewing of E. galactitella is shiny white. It most resembles E. kalki Parenti , which is more stoutbodied with broader wings. Their genitalia are entirely different (cf. Kaila 2005). The male genitalia are similar to those of E. deresyensis , but differ by the width of uncus lobes: they are twice as long as broad in E. galactitella , about as long as broad in E. deresyensis . The female genitalia most resemble those of E. elsaella . They differ by the size of antrum which is significantly larger in E. galactitella . It also lacks a sclerotized band typical of E. elsaella .

Biology. This species has been reared in an ex ovo experiment on Stipa pennata L. ( Poaceae ) in the laboratory ( Parenti 2004).

Distribution. France, Italy, Spain, Russia and Switzerland. Parenti (2001) also mentions Turkey. This record is based on the erroneous synonymy of E. deresyensis and E. galactitella by Kaila (1999a).

Remarks. E. galactitella is referred to as OTU 4 in Mutanen et al. (2015). The synonymy of E. bustilloi Traugott-Olsen and E. galactitella Eversmann was established by Parenti & Domínguez (1995) and again by Parenti (2004) with a somewhat more detailed account. The single known specimen of E. madridensis was collected together with the holotype of E. bustilloi . The E. madridensis specimen lacks an abdomen. Its external appearance is identical to that of E. galactitella ( E. bustilloi , a synonym of it) with a shiny white forewing. E. madridensis is considered a synonym of E. galactitella .
