Varenneleg., genitalia slide JN n°31706 ( RCTV). BOLD Specimen ID TLMF25313; BOLD Sequence ID LEGEL367-18.  BIN: BOLD:ABW4899 Identity:  Elachista maculosellaChrétien, 1896,  syn. nov.( Fig. 10)   Remarks.  Elachista karsticolawas described from a male holotypeand separated from the randomly selected species of the  E. bifasciellaspecies-group  E. sebastellaKaila, 2015,  E. sulcsiellaSavenkov, 2013,  E. orstadiiPalm, 1943and  E. gruenewaldiParenti, 2002on genitalia characters ( Varenne & Nel 2018). The species was recently included in the World Catalogue of Elachistidaeas valid taxon ( Kaila 2019). However, the successfully sequenced holotypeshares the barcode with  E. maculosella, a species described from Franceand 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. karsticolawith  E. maculosella. 2017-04-12 RCTV Th. Varenne France 950 Alpes-Maritimes Coursegoules 28 329 1 holotype
