Remarks. The identity of Eucosma carduana described from France appears doubtful, and it is probably not conspecific with Eucosma cana and related taxa. This is indicated in particular by the reference to white forewings in the original description. Further studies, especially of potentially remaining syntype specimens, are necessary to clarify this issue.
