Abstract

Patterns of rarity, endemism, and vulnerability are known for four species of yellow-eared bats of the genus Vampyressa: V. melissa, V. voragine, V. elisabethae, and V. sinchi, the last two described based on skull and external morphology. We extracted DNA from the holotypes of V. elisabethae and V. sinchi using strict ancient DNA protocols and sequenced the complete cytochrome-b gene of the mtDNA to investigate the phylogenetic relationships within the genus and employed species-delimitation tests to evaluate the validity of all the currently named species of Vampyressa. The resulting tree topology and our species-delimitation analyses corroborate the validity of V. elisabethae and V. voragine, but places V. sinchi in V. melissa. Based on these results and phenotypic variation, we recognize five valid species in Vampyressa and treat sinchi as a subspecies of a polytypic V. melissa; for which we provide a rediagnosis. Our results show that V. elisabethae is as highly divergent genetically as it is morphologically, and suggest that V. thyone, one of the two species of Vampyressa known to have wide distributions, is a species complex requiring further investigation.

稀有黄耳蝙蝠Vampyressa Thomas, 1900年的历史DNA(翼翅目，Phyllostomidae)澄清了属内的系统发育和物种界限

Vampyressa属四种黄耳蝙蝠的稀有性、地方性和脆弱性模式是已知的：V.melissa、V.voragine、V.elisabethae和V.sinchi，最后两种是根据头骨和外部形态描述的。我们使用严格的古代DNA方案从伊丽莎白病毒和新奇病毒的正模中提取DNA，并对线粒体DNA的完整细胞色素b基因进行测序，以研究该属内的系统发育关系，并使用物种划界测试来评估目前命名的所有Vampyressa物种的有效性。由此产生的树拓扑结构和我们的物种划界分析证实了伊丽莎白氏葡萄和沃拉吉葡萄的有效性，但将辛奇葡萄放在了梅利萨葡萄中。基于这些结果和表型变异，我们识别出五个有效的Vampyressa物种，并将sinchi视为一个多型V.melissa的亚种；我们对此进行了重新诊断。我们的研究结果表明，伊丽莎白病毒在基因上和形态上都有很大的差异，并表明百里香病毒是已知分布广泛的两种吸血鬼之一，是一个需要进一步研究的复杂物种。

期刊介绍： Systematics and Biodiversity is devoted to whole-organism biology. It is a quarterly, international, peer-reviewed, life science journal, without page charges, which is published by Taylor & Francis for The Natural History Museum, London. The criterion for publication is scientific merit. Systematics and Biodiversity documents the diversity of organisms in all natural phyla, through taxonomic papers that have a broad context (not single species descriptions), while also addressing topical issues relating to biological collections, and the principles of systematics. It particularly emphasises the importance and multi-disciplinary significance of systematics, with contributions which address the implications of other fields for systematics, or which advance our understanding of other fields through taxonomic knowledge, especially in relation to the nature, origins, and conservation of biodiversity, at all taxonomic levels. The journal does not publish single species descriptions, monographs or applied research nor alpha species descriptions. Taxonomic manuscripts must include modern methods such as cladistics or phylogenetic analysis.
