Diagnosis. E. disemiella has distally grey forewing termen fringe scales. As such, it resembles E. maboulella . The differentiation of these species is explained in the diagnosis of E. maboulella .
Biology. The larvae of E. disemiella mine the leaves of Ampelodesmos mauritanicus (Poiret) T. Durand & Schinz (Poaceae) (Parenti & Varalda 1994; J. Tabell, personal communication).
Distribution. Italy (Sardinia) and Spain, including Mallorca and Tunisia.
Remarks. E. disemiella is referred to as OTU 14 in Mutanen et al. (2015).
