Examined material. Holotype Ƌ: France , Alpes-Maritimes , Courségoules , 950 m , 12.IV.2017 , Th. Varenne leg., genitalia slide JN n°31706 ( RCTV ). BOLD Specimen ID TLMF 25313; BOLD Sequence ID LEGEL367-18. BIN: BOLD:ABW4899 Identity: Elachista maculosella Chrétien, 1896 , syn. nov. ( Fig. 10 ) Remarks. Elachista karsticola was described from a male holotype and separated from the randomly selected species of the E. bifasciella species-group E. sebastella Kaila, 2015 , E. sulcsiella Savenkov, 2013 , E. orstadii Palm, 1943 and E. gruenewaldi Parenti, 2002 on genitalia characters ( Varenne & Nel 2018 ). The species was recently included in the World Catalogue of Elachistidae as valid taxon ( Kaila 2019 ). However, the successfully sequenced holotype shares the barcode with E. maculosella , a species described from France and corresponding in morphology but not considered as potential conspecific by Varenne & Nel (2018) .According to Kaila (pers. comm.) the taxon falls in the range of intraspecific variation of E. maculosella . We therefore synonymize E. karsticola with E. maculosella .
