The Honduran white bat, Ectophylla alba (Allen 1982), is one of eight species belonging to the family Phyllostomidae that exclusively roosts in tents. Due to its restricted distribution, habitat specificity, and diet requirements, E. alba has been strongly affected by habitat loss and fragmentation during the last decade. In this study, we developed the first genomic resource for this species; we assembled and analyzed in detail the complete mitochondrial genome of E. alba. The mitogenome of E. alba is 16,664 bp in length and is comprised of 13 protein coding genes (PCGs), 2 ribosomal RNA genes, 22 transfer RNA genes (tRNAs), and a putative Control Region (CR) 1,232 bp in length. Gene arrangement in the mitochondrial chromosome of E. alba is identical to that reported before in other species of co-familiar bats. All PCGs are under purifying selection, with atp8 experiencing the least selective pressure. In all PCGs, codons ending with adenine are preferred over others ending in thymine and cytosine. Except tRNA-Serine 1, all tRNAs exhibit a cloverleaf secondary structure. The CR of E. alba exhibits three domains commonly described in other mammals, including bats; extended terminal associated sequences (ETAS), central, and conserved sequence block (CSB). A ML phylogenetic reconstruction of the family Phyllostomidae based on all 13 mitochondrial PCGs confirms the monophyletic status of the subfamily Sternodermatinae and indicates the close relationship between E. alba and the genus Artibeus. This is the first genomic resource developed for E. alba and represents the first step to improving our understanding of the genomic underpinnings involved in the evolution of specialization as well as acclimatization and adaptation to local and global change of specialist bats.

洪都拉斯白蝙蝠，Ectophylla alba (Allen 1982)，是属于只栖息在帐篷中的叶蝠科的八种物种之一。由于其分布受限、栖息地特殊性和饮食要求，E. alba在过去十年中受到栖息地丧失和破碎化的强烈影响。在这项研究中，我们为该物种开发了第一个基因组资源；我们组装并详细分析了E. alba的完整线粒体基因组。E. alba 的有丝分裂基因组长度为 16,664 bp，由 13 个蛋白质编码基因 (PCG)、2 ​​个核糖体 RNA 基因、22 个转移 RNA 基因 (tRNA) 和一个长度为 1,232 bp 的推定控制区 (CR) 组成。线粒体染色体中的基因排列E. alba与之前在其他共同熟悉的蝙蝠物种中报道的相同。所有 PCG 都处于纯化选择之下，atp8的选择压力最小。在所有 PCG 中，以腺嘌呤结尾的密码子优于其他以胸腺嘧啶和胞嘧啶结尾的密码子。除了 tRNA-丝氨酸 1，所有 tRNA 都表现出三叶草二级结构。E. alba的 CR展示了其他哺乳动物（包括蝙蝠）中常见的三个结构域；扩展终端相关序列 (ETAS)、中央和保守序列块 (CSB)。基于所有 13 种线粒体 PCG 对 Phyllostomidae 家族的 ML 系统发育重建证实了 Sternodermatinae 亚科的单系状态，并表明E. alba之间的密切关系和Artibeus属。这是为E. alba开发的第一个基因组资源，代表了提高我们对参与专业化进化以及适应当地和全球变化的专业蝙蝠的基因组基础的理解的第一步。
