The Neotropical bat genus Platyrrhinus is one of the most speciose genera in the family Phyllostomidae. It includes 20 species of frugivorous bats that are endemic to the Neotropics. Platyrrhinus chocoensis is a species distributed from southern Panama southward into northern Ecuador on the lowlands and mid elevations of the Pacific coast of northern South America, across the Choco Biogeographic region, a hot-spot of biodiversity, extending west of the Andes. Due to its association with the Chocoan rainforest, P. chocoensis was designated as one of the two species of bats included in the Red List of Colombian mammals. Another species of Platyrrhinus, P. dorsalis, also occurs in Colombia and Ecuador along both slopes of the Andes. In contrast with P. chocoensis, P. dorsalis is considered a relatively common bat species within the Least Concern category of the International Union for Conservation of Nature. We evaluate the systematics and taxonomy of both species, P. chocoensis and P. dorsalis, using a combination of morphometric and molecular analyses. Although our morphometric analyses support a consistent morphological differentiation between these two taxa, the analyses of mtDNA sequences of Cyt-b and ND2 revealed that P. chocoensis and P. dorsalis have no differentiation at the genetic level for the analyzed markers (0.7%); therefore, we recognize P. chocoensis as a junior synonym of P. dorsalis. In addition, our results support the recognition of two subspecies within P. dorsalis: the nominate P. d. dorsalis and P. d. chocoensis. Finally, we discuss the biogeographic implications of our findings, in particular the consequences of the synonymization of P. chocoensis, that also warrants the reevaluation of the taxonomic and conservation status of P. dorsalis populations from the Chocoan domain.

基于形态测量和遗传分析的 Platyrrhinus chocoensis (Chiroptera: Phyllostomidae) 的系统学和分类学：对生物地理学和保护的影响

新热带蝙蝠属 Platyrrhinus 是叶蝠科中最特殊的属之一。它包括 20 种新热带地区特有的食果蝙蝠。Platyrrhinus chocoensis 是一种从巴拿马南部向南分布到厄瓜多尔北部的物种，位于南美洲北部太平洋沿岸的低地和中海拔地区，横跨安第斯山脉以西延伸的生物多样性热点 Choco Biogeographic 区域。由于它与 Chocoan 热带雨林的联系，P. chocoensis 被指定为哥伦比亚哺乳动物红色名录中的两种蝙蝠之一。另一种侧柏，P. dorsalis，也出现在哥伦比亚和厄瓜多尔，沿安第斯山脉的两个斜坡。与 P. chocoensis 相比，P. dorsalis 被认为是国际自然保护联盟最不关心类别中相对常见的蝙蝠物种。我们使用形态计量学和分子分析的组合来评估 P. chocoensis 和 P. dorsalis 这两个物种的系统学和分类学。尽管我们的形态计量分析支持这两个分类群之间一致的形态差异，但对 Cyt-b 和 ND2 的 mtDNA 序列的分析表明，P. chocoensis 和 P. dorsalis 在分析标记的遗传水平上没有差异 (0.7%)；因此，我们认为 P. chocoensis 是 P. dorsalis 的初级同义词。此外，我们的结果支持在 P. dorsalis 中识别出两个亚种：提名 P. d. 背和 P. d. 巧克力 最后，我们讨论了我们发现的生物地理学意义，
