Remarks: Dufrane (1957: 13) described klimeschi as a ‘race géographique’ of E. cerusella , but explicitly stated it as ‘sp. nov.’ In the same publication he named Elachista cerusella f. juncta . This name fulfils the provisions of ICZN (1999: 45.6.4) and is to be treated as a species-group name, stat. nov.
