Single nucleotide polymorphism‐based species phylogeny of greater fritillary butterflies (Lepidoptera: Nymphalidae: Speyeria) demonstrates widespread mitonuclear discordance

The systematics of Speyeria butterflies has historically been complicated by intraspecific variability that has challenged efforts to delimit species and reconstruct phylogenies. Our study presents a phylogenetic comparison of genomic single nucleotide polymorphisms (SNPs) and mitochondrial COI gene sequences, with comprehensive taxon sampling that includes 15 species and 46 subspecies. Increased sampling of genetic markers and taxa improved the...
