Diagnosis. Externally, E. dispunctella is similar to most other species in the E. dispunctella complex with unicolorous forewing fringe. Therefore examination of the genitalia is necessary for its identification. E. dispunctella belongs to those species that have a nearly straight and narrow, elongate phallus. The phallus length of E. dispunctella is about equal to that of valva, distinguishing it from the similar, possibly sympatric species: the phallus of E. dalmatiensis and E. grandella is shorter than the valva, that of E. hispanica is significantly longer than valva. The juxta lobes are devoid of setae. The female genitalia are characterized by the corpus bursae which has a conspicuous appendix bursae. Among the species with an appendix bursae, the shape and size of it is fairly equal to that of E. dispunctella only in E. maboulella. The corpus bursae of E. maboulella is, however, smaller than that of E. dispunctella.
Biology. According to Heckford (2010), E. dispunctella often inhabits serpentine and limestone sites where its hostplant Festuca rubra L. (Poaceae) grows in England.
Distribution. Austria, Croatia, England, France, Germany, Hungary, Kazakhstan, Latvia, Poland, Russia, Slovakia, Turkey, and Ukraine.
Remarks. According to Stainton (1858), Vienna and Ratisbon (now Regensburg) are mentioned as the distribution of E. dispunctella; the latter does not match Duponchel’s original account which implies eastern Austria to be the origin of the type series, so the original material likely originates from the Vienna region.
The lectotype of E. dispunctella, in Musée Nationale d’Histoire Naturelle, Paris, is lacking the abdomen. Therefore its identification is not possible, in particular as several species of the E. dispunctella complex occur in the area of its collecting site (eastern Austria). Of these, E. grandella can be ruled out due to its larger size. The other known alternatives are the taxa listed here as synonyms of E. dispunctella, as well as E. dalmatiensis, whose male genitalia are depicted as representing E. dispunctella in Traugott-Olsen (1992). The collecting site of that specimen is not mentioned. Traugott-Olsen lists, besides Austrian localities, also Macedonia: Skopje in the E. dispunctella, material studied by him. This locality would be within the verified range of E. dalmatiensis of which no Austrian specimen was found in the present study. Until the genitalia slide from which the illustration was made has been examined, its origin remains unclear. It is probably impossible to establish with certainty what is the ‘real’ E. dispunctella, but the acquired knowledge and conformity of nomenclature in reviews and regional checklists predating, and to some extent also persisting after Traugott-Olsen (1992) are here used as guidelines in the decision of the identity of this name.
The barcode of the E. skulei holotype is slightly different from other specimens, including holotypes of several nominal species grouped with E. dispunctella (difference to closest E. dispunctella 1.9%). This difference is minor, possibly due to its somewhat distant collecting site from other samples of the widespread E. dispunctella. In the absence of any other differentiating characters between the E. dispunctella and E. skulei, they are considered conspecific.
E. dispunctella is referred to as OTU 8 in Mutanen et al. (2015). The record of E. grandella from Germany (Biesenbaum 1995) is here interpreted to represent E. dispunctella, as the phallus/valva length ratio in the genital illustration of the German specimen matches E. dispunctella, not E. grandella.
