摘要

较小的黄肩蝙蝠，Sturnira nana，是新世界叶鼻蝙蝠(Phyllostomidae)中最多样化属的一员。该物种被认为是秘鲁特有的物种，直到2009年，研究人员在厄瓜多尔东南部的Cordillera del Cóndor捕获了一系列个体，并将它们确定为S. nana。为了评估厄瓜多尔种群与秘鲁S. nana的分类地位，我们分析了细胞色素b基因序列和颅齿测量数据。此外，我们使用主成分分析来阐明气候生态位的差异。我们的分析表明，目前鉴定为来自厄瓜多尔和秘鲁的S. nana的种群在遗传、形态和生态上都是不同的。在这里，我们正式将厄瓜多尔的小Sturnira种群描述为一个新物种。

On the Taxonomic Identity of Sturnira nana Gardner and O'Neil, 1971 (Chiroptera: Phyllostomidae), from Ecuador, with the Description of a New Species of Sturnira

The lesser yellow-shouldered bat, Sturnira nana, is a member of the most diverse genus of the New World leaf-nosed bats (Phyllostomidae). This species was considered endemic to Peru until 2009 when researchers captured a series of individuals in the Cordillera del Cóndor of southeastern Ecuador and identified them as S. nana. To assess the taxonomic status of this Ecuadorian population in relation to S. nana from Peru, we analyzed cytochrome b gene sequences and craniodental measurement data. In addition, we used principal component analysis to elucidate differences in climatic niches. Our analyses suggest that populations currently identified as S. nana from Ecuador and Peru are genetically, morphologically, and ecologically divergent. Herein, we formally describe the population of small Sturnira from Ecuador as a new species.

期刊介绍： The Novitates (Latin for "new acquaintances"), published continuously and numbered consecutively since 1921, are short papers that contain descriptions of new forms and reports in zoology, paleontology, and geology.
