The intrageneric relationships of the pampatheriid genus Scirrotherium and its affinities with supposedly related genera, i.e., Kraglievichia and Holmesina, are revised through parsimony phylogenetic analyses and new comparative morphological descriptions. For this work, unpublished material of pampatheriids (numerous osteoderms, one partial skull and a few postcranial bones) from Neogene formations of Colombia was analyzed. The results show that Scirrotherium is paraphyletic if we include all its referred species, i.e., Scirrotherium hondaensis, S. carinatum and S. antelucanus. The species S. carinatum is closer to Kraglievichia paranensis than to S. hondaensis or S. antelucanus, therefore the new name K. carinatum comb. nov. is proposed. The relationship among S. hondaensis and S. antelucanus could not be resolved, so these species should be designated in aphyly. In spite of failing to recover S. hondaensis and S. antelucanus as one single clade, here is preferred to maintain the generic name Scirrotherium in both species based on diagnostic evidence. New emended diagnoses for Scirrotherium, S. hondaensis and Kraglievichia are provided. The genus Holmesina was found to be monophyletic and positioned as the sister clade of Scirrotherium + Kraglievichia. The evolutionary and biogeographic implications of the new phylogeny and taxonomic re-arrangements are discussed. A possible geographic origin of the family Pampatheriidae and Scirrotherium in low latitudes of South America as early as Early Miocene times is claimed. The South American ancestor or sister taxon of Holmesina is predicted to be morphologically more similar to Scirrotherium than to Kraglievichia.

对Scirrotherium Edmund和Theodor属的系统修订和重新定义，1997年（Cingulata，Pampatheriidae）：对pampatheriids的起源和包括Holmesina在内的南美血统的演变的启示

在pampatheriid属的intrageneric关系Scirrotherium及其与所谓近缘属，即亲和力，Kraglievichia和Holmesina，通过简约的系统发育分析和比较新的形态描述修订。对于这项工作，分析了来自哥伦比亚新​​近纪地层的未公开的氨甲蝶呤材料（大量的真皮，一个颅骨部分和一些颅后骨）。结果表明，Scirrotherium是并系，如果我们包括所有种类所指，即Scirrotherium hondaensis，S. carinatum和S. antelucanus。Carinatum S.种更接近Kraglievichia paranensis比S. hondaensis或S. antelucanus，因此新的名称K. carinatum梳。十一月 被提议。本田沙门氏菌和前沙门氏菌之间的关系无法解决，因此应在属上进行命名。尽管未能将本田链球菌和前沙门氏菌作为单个进化枝恢复，但根据诊断证据，在这两个物种中都优选保留通用名称Scirrotherium。新仔细的校勘诊断为Scirrotherium，S. hondaensis和Kraglievichia提供。属Holmesina被认为是单生的，被定位为Scirrotherium + Kraglievichia的姐妹进化枝。讨论了新的系统发育和分类学重新安排的进化和生物地理意义。早在中新世早期，就有人发现了南美低海拔地区的amp蝶科和Sc螨科的可能地理起源。南美祖先或姐妹类群Holmesina预计在形态上更类似于Scirrotherium比Kraglievichia。
