Eupeyerimhoffiaarchimedis (Strasser, 1965) is redescribed based on several specimens collected at a number of sites close to the type locality on Sicily, Italy. Scanning electron microscopy is used to illustrate several unusual morphological characters for a member of the Glomerida for the first time. A fragment of the mitochondrial COI gene (668bp) is sequenced for the first time in Eupeyerimhoffia to provide a species-specific barcode and to gain first insights into the genetic distances between the genera in the widespread family Protoglomeridae. The novel sequences are compared to representatives of all other genera of the family: Protoglomerisvasconica (Brölemann, 1897) from northern Spain, the dwarfed Glomerellinalaurae Silvestri, 1908 from Italy and Glomeroidesprimus (Silvestri, 1929) from western North America. The addition of COI sequences from the two other families of the Glomerida renders the family Protoglomeridae paraphyletic with Glomeroidesprimus being more closely related to Glomeridellaminima (Latzel, 1884) than to the other genera in the family. The large genetic distances (13.2-16.8%) between Eupeyerimhoffia and the other genera in the order, as well as its unusual morphological characters, including unique morphological adaptations to roll into a ball, are probably an indication of the old age of the group.
基于在意大利西西里岛模式产地附近的多个地点采集的多个标本，对阿基米德欧佩耶里姆霍菲亚（Strasser，1965）进行了重新描述。首次使用扫描电子显微镜展示了球蚓目成员的几个不寻常的形态特征。首次对欧佩耶里姆霍菲亚的线粒体COI基因片段（668bp）进行测序，以提供物种特异性条形码，并首次深入了解广泛分布的原球蚓科各属之间的遗传距离。将新序列与该科所有其他属的代表进行比较：来自西班牙北部的巴斯孔原球蚓（Brölemann，1897）、来自意大利的侏儒劳拉球蚓（Silvestri，1908）和来自北美西部的原球蚓属Primus（Silvestri，1929）。来自球蚓目的另外两个科的COI序列的加入使得原球蚓科成为并系群，其中原球蚓属Primus与最小球蚓（Latzel，1884）的关系比与该科其他属的关系更密切。欧佩耶里姆霍菲亚与该目中其他属之间的大遗传距离（13.2 - 16.8%），以及其不寻常的形态特征，包括独特的卷成球状的形态适应，可能表明该类群年代久远。
