The hairy long-nosed armadillo, currently referred as Dasypus (Cryptophractus) pilosus, is an enigmatic species endemic to montane cloud forests and subparamo of Peruvian Andes. Its strikingly different external features, which include the carapace concealed by abundant hair, the presence of more movable bands, and a slender skull, have raised questions regarding its taxonomic status as subgenus or as genus. This paper assesses this issue based on a cladistic study and provides a detailed comparative description of the species, including the first account on the distinctive ornamentation of its osteoderms. Based on several unique characters in the carapace, skull, mandible, and teeth, as well as on the external phylogenetic position relative to other Dasypus, we favor the assignment of the hairy long-nosed armadillo to other genus. As result, we revalidate the original generic epithet, so that the valid name of the species is Cryptophractus pilosus Fitzinger, 1856.
毛长鼻犰狳，目前被称为达斯ypus（隐犰狳属）pilosus，是一种神秘的物种，特产于秘鲁安第斯山脉的山地云雾森林和亚高山带。其显著不同的外部特征，包括被大量毛发覆盖的甲壳、更多可活动的条带以及细长的头骨，引发了关于其作为亚属或属的分类地位的问题。本文基于支序分类研究评估了这一问题，并对该物种进行了详细的比较描述，包括对其骨板独特纹饰的首次描述。基于甲壳、头骨、下颌骨和牙齿中的几个独特特征，以及相对于其他达斯ypus的外部系统发育位置，我们倾向于将毛长鼻犰狳归入其他属。因此，我们重新确认了原始的属名，该物种的有效名称为Cryptophractus pilosus Fitzinger，1856。
