The subgenus Pteronotus (naked-backed bats) comprises three species, P. davyi, P. fulvus, and P. gymnonotus, which are distinguished from other members of the genus Pteronotus by wing membranes that are fused along the dorsal midline and by skulls with noticeably upturned rostrums. Pteronotus davyi currently includes two morphologically differentiated subspecies, P. d. davyi and P. d. incae, with strikingly disjunct geographic ranges. Whereas the nominotypical form is found in Central America, the Caribbean coastal region of northern South America, and the Lesser Antilles, the subspecies P. d. incae is restricted to a small area in northwestern Peru; to date, the phylogenetic relationships of these nominal taxa have not been explored. In the present contribution, we employed analyses of mitochondrial gene sequences, morphometrics, and qualitative-morphological comparisons to provide new information on P. d. incae and place the taxon in a phylogenetic context. Our results suggest that the geographically disjunct populations of P. davyi are genetically very similar even though they are morphologically and ecologically distinct. Recognizing that speciation is a process with intermediate stages that merit formal recognition, we support the retention of incae as a valid subspecies of Pteronotus davyi.

关于Pteronotus davyi incae Smith的分类学同一性，1972年（鳞翅目：Mormoopidae）

Pteronotus亚种（裸背蝙蝠）由P. davyi，P。fulvus和P. Gymnonotus三种构成，它们与Pteronotus属的其他成员的区别在于其翼膜沿着背中线融合在一起，而头骨被讲台上翘。目前，Pteronotus davyi包括两个形态分化的亚种P. d。davyi和P. d。Incae，地理范围截然不同。而在中美洲，南美洲北部的加勒比海沿海地区以及小安的列斯群岛的亚种P. d。中发现了这种基因型。印加人仅限于秘鲁西北部的一小片地区；迄今为止，尚未探索这些标称类群的系统发育关系。在目前的贡献中，我们采用了线粒体基因序列分析，形态计量学，以及定性形态的比较，以提供有关P的新信息。将分类单元放置在系统发育背景中。我们的研究结果表明，尽管地理上分离的种群在形态上和生态上都非常相似，但它们在遗传上却非常相似。认识到物种形成是一个值得正式承认的中间阶段的过程，我们支持保留Incae作为Pteronotus davyi的有效亚种。
