Accurate species delimitations are essential for establishing efficient conservation programs.Gortyna borelii (Noctuidae) is a threatened and protected moth, with a widespread, but localisedin a range of meadows, forest clearings and edges in Europe. Larvae are internal feeders on alimited number of Peucedanum species, that are heavily impacted by intensive mowing regimes.Preliminary DNA barcode data from a few individuals showed a deep mitochondrial split in Francesuggesting a possible cryptic species complex. We DNA barcoded an additional 43 individualssampled across France that confirmed the existence of two BINs, with a genetic divergenceof 2.79%, one in Southeastern France (Maritime Alps) and Corsica and another in Western,central France and Eastern Pyrenees. RADseq data (9961 SNPs) from 34 individuals confirmedthe existence of two clades but also revealed a substructure in five populations in France. Theestimation of population genetic indices such as genetic diversity and inbreeding coefficientenabled us to assess the genetic status of these populations. This new insight into the geneticcomposition of G. borelii must be integrated into the conservation strategies to save this flagshipspecies from extinction.
