Three complete mitochondrial genomes of South American electric fishes (Gymnotiformes), derived from high-throughput RNA sequencing (RNA-Seq), are reported herein. We report the complete mitochondrial genome of the bluntnose knifefish n.sp. VERD, determined from newly sequenced data. We also provide the complete mitochondrial genomes for and the electric eel , assembled from previously published transcriptome data. The mitochondrial genomes of n.sp. VERD and have 13 protein-coding genes, 1 D-loop, 2 ribosomal RNAs and 22 transfer RNAs, and are 16,547, 16,667 and 16,906 bp in length, respectively. Phylogenetic analysis of the eight available mitochondrial genomes of gymnotiform fishes shows to be the sister lineage of other gymnotiformes, contradicting the "Sinusoidea" hypothesis that Apteronotidae and Sternopygidae are sister taxa.
本文报道了通过高通量RNA测序（RNA-Seq）获得的三种南美电鱼（裸背电鳗目）的完整线粒体基因组。我们报道了根据新测序数据确定的钝吻刀鱼新物种n.sp. VERD的完整线粒体基因组。我们还提供了从先前发表的转录组数据组装而来的线翎电鳗和电鳗的完整线粒体基因组。钝吻刀鱼新物种n.sp. VERD和线翎电鳗的线粒体基因组有13个蛋白质编码基因、1个D环、2个核糖体RNA和22个转运RNA，长度分别为16,547、16,667和16,906碱基对。对裸背电鳗目鱼类现有的八个线粒体基因组进行的系统发育分析表明，钝吻刀鱼新物种n.sp. VERD是其他裸背电鳗目的姐妹谱系，这与无背电鳗科和颈电鳗科是姐妹类群的“新电鳗类”假说相矛盾。
