, , and (Family Cyprinidae, Order Cypriniformes) are endemic and endangered fishes in the southwestern United States. We present complete mitochondrial genomes for each species. Each mitochondrion consisted of 13 protein-coding genes, 2 ribosomal (rRNA) genes, 22 transfer RNA (tRNA) genes, and a single control region (D-loop), and gene order was consistent with other cyprinid fishes. Total genome lengths were 16,593 base pairs (bp) for . , 16,705 bp for . , and 16,802 for . The GC content in . and was 44%, but higher in . at 48%. Phylogenetic trees were generated to confirm relationships inferred via novel mitogenomes, and best-supported trees were consistent with previous research.
鲤科（鲤形目）的[具体鱼类名称1]、[具体鱼类名称2]和[具体鱼类名称3]是美国西南部特有的濒危鱼类。我们展示了每个物种的完整线粒体基因组。每个线粒体由13个蛋白质编码基因、2个核糖体（rRNA）基因、22个转移RNA（tRNA）基因和一个单一的控制区（D环）组成，基因顺序与其他鲤科鱼类一致。[具体鱼类名称1]的基因组总长度为16,593碱基对（bp），[具体鱼类名称2]为16,705 bp，[具体鱼类名称3]为16,802 bp。[具体鱼类名称1]和[具体鱼类名称2]的GC含量为44%，但[具体鱼类名称3]的GC含量较高，为48%。生成了系统发育树以确认通过新的有丝分裂基因组推断出的关系，支持度最高的树与先前的研究一致。
