Dasypus kappleri is the largest species of the genus Dasypus and is restricted to the Amazonian rainforest biome. Over the last century, related taxa have been described and synonymized without comprehensive analyses, and the current classification involving two subspecies, Dasypus k. kappleri and Dasypus k. pastasae, has never been revised. The aim of this work is to clarify the taxonomy of Dasypus kappleri through integrative morphological and morphometric analyses. We examined 70 specimens housed in scientific collections as well as photographs of the type specimens of five nominal taxa. Three methodologies (discrete characters, linear and geometric morphometrics) were employed. All results converged on the recognition of three allopatric groups, each with diagnostic qualitative and quantitative traits, that we recognize as full species: Dasypus kappleri Krauss, 1862, occurs in the Guiana shield; Dasypus pastasae (Thomas, 1901) is distributed from the eastern Andes of Peru, Ecuador, Colombia, and Venezuela south of the Orinoco River into the western Brazilian Amazon; and Dasypus beniensis Lönnberg, 1942, occurs in the lowlands of Amazonian Brazil and Bolivia to the south of the Madre de Dios, Madeira, and lower Amazon rivers. This revision raises to nine the number of living species of Dasypus.
卡氏三趾树懒（Dasypus kappleri）是三趾树懒属中体型最大的物种，仅分布于亚马逊雨林生物群落。在过去的一个世纪里，相关分类单元未经全面分析就被描述并同义化，目前涉及两个亚种，即卡氏三趾树懒指名亚种（Dasypus k. kappleri）和帕斯塔三趾树懒亚种（Dasypus k. pastasae）的分类从未修订过。这项工作的目的是通过综合形态学和形态测量分析来阐明卡氏三趾树懒的分类学。我们检查了保存在科学收藏中的70个标本以及五个命名分类单元模式标本的照片。采用了三种方法（离散特征、线性和几何形态测量）。所有结果都一致认为存在三个异域种群，每个种群都有诊断性的定性和定量特征，我们将其认定为完整物种：卡氏三趾树懒（Dasypus kappleri Krauss，1862）分布于圭亚那地盾；帕斯塔三趾树懒（Dasypus pastasae (Thomas，1901)）分布于秘鲁、厄瓜多尔、哥伦比亚和委内瑞拉安第斯山脉东部，奥里诺科河以南至巴西西部亚马逊地区；贝尼三趾树懒（Dasypus beniensis Lönnberg，1942）分布于巴西亚马逊地区和玻利维亚的低地，南至马德雷德迪奥斯河、马德拉河和亚马逊河下游。这次修订使三趾树懒属现存物种数量增至九个。
