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 match between genetic clusters, obtained with both phylogenetic and cluster‐based analyses, and species previously detected using morphology, as well as showing two species delimitations that may need revision. We also recovered extensive mitonuclear discordance between genomic SNPs and the COI gene, confirming that mitochondrial DNA does not reliably identify several species at broad geographic scales. Resolution of the relationships of Speyeria species demonstrates the importance of sampling variation across the whole genome, and provides an essential foundation for understanding the evolution of this charismatic clade of North American butterflies.

基于单核苷酸多态性的大贝母蝴蝶（鳞翅目：蛱蝶科：Speyeria）的物种系统发育表明广泛的线粒体核不一致性

Speyeria 蝴蝶的系统学历来因种内变异而变得复杂，这对划定物种和重建系统发育的努力提出了挑战。我们的研究展示了基因组单核苷酸多态性 (SNP) 和线粒体 COI 基因序列的系统发育比较，以及包括 15 个物种和 46 个亚种的综合分类群抽样。遗传标记和分类群采样的增加改善了通过系统发育和基于聚类的分析获得的遗传聚类与先前使用形态学检测到的物种之间的匹配，并显示了可能需要修改的两个物种定界。我们还发现基因组 SNP 和 COI 基因之间存在广泛的线粒体核不一致，证实线粒体 DNA 不能可靠地识别广泛地理范围内的几个物种。
