The Macaroni penguin is a small crested penguin. In this study, the complete mitochondrial genome of is revealed for the first time. The mitogenome sequence is circular and 17,059 bp in length. It contains 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, and two ribosomal RNA (rRNA) genes similar to other Spheniscidae species. The total nucleotide composition is 30.53% (A), 32.86% (C), 13.96% (G), and 22.66% (T), and 46.81% for overall GC contents. The phylogenetic analysis shows a close relationship between and . Our findings would be useful for further studies on phylogenetics and evolutionary history of the genus .
马可罗尼企鹅是一种小型冠企鹅。在本研究中，首次揭示了其完整的线粒体基因组。线粒体基因组序列呈环状，长度为17,059 bp。它包含13个蛋白质编码基因（PCGs）、22个转运RNA（tRNA）基因和两个核糖体RNA（rRNA）基因，与其他企鹅科物种相似。总核苷酸组成是30.53%（A）、32.86%（C）、13.96%（G）和22.66%（T），总体GC含量为46.81%。系统发育分析表明[此处原文缺失相关物种名称]与[此处原文缺失相关物种名称]之间存在密切关系。我们的研究结果将有助于对该属的系统发育学和进化历史进行进一步研究。
