We describe a highly isolated population of hairstreak butterfly from Waterton Lakes National Park, Alberta, Canada, as new species, Satyrium curiosolus sp. nov. , previously recognized semiluna (Half-moon Hairstreak). propose “Curiously Isolated Hairstreak” the common name due to its disjunct and unusual distribution. Previous whole-genome analyses revealed S. has extremely low genomic diversity is divergent nearest populations in British Columbia Montana, more than 400 km distant. Further analysis suggested prolonged inbreeding isolation for up ~40,000 years BP. Ecological niche modeling indicated that occupies environmental conditions are distinct suggesting divergence driven by long-term geographical ecological separation. While host plant ant associations have not been definitively resolved, they likely differ between . As part this description, we provide consensus sequences each individual type series identify 21,985 single nucleotide polymorphisms (SNPs) divergently fixed including 117 unlinked SNPs distributed across genome putative diagnostic markers. Previously listed Endangered Canada should retain conservation status extreme isolation, small size, flatlined diversity. species recognition testable hypothesis under General Lineage Concept recommend further research explore taxonomy, relationships, greater complex, fuliginosa
