is a genus of small, thin-bodied millipedes found in deciduous forests of North America. Poorly understood, these organisms inhabit decaying wood and have morphologically conserved and difficult-to-identify sexual characters that have limited study historically. Recent use of scanning electron microscopy has uncovered variation in male genitalia that was previously unknown in the genus. The distribution of and the extent of this variability across the continent, however, were undocumented, and a wealth of natural history collections remained uncatalogued. Here a new species of is described from New Mexico, , natural history collections are utilized to create a comprehensive map of the genus, and a neotype established for the type species, Cope, 1869. Analysis of the cytochrome oxidase I gene (COI) for was completed for the type series and individuals across the species distribution, but little variation was found. joins and Shear & Marek, 2009 as the only members of the genus.
是一类小型、身体细长的千足虫，发现于北美的落叶林中。人们对这些生物了解甚少，它们栖息在腐烂的木材中，具有形态上保守且难以识别的性特征，这在历史上限制了相关研究。最近使用扫描电子显微镜发现了该属以前未知的雄性生殖器变异。然而，该属在整个大陆的分布以及这种变异性的程度尚无记录，大量的自然历史标本仍未编目。这里描述了一种来自新墨西哥州的新物种，利用自然历史标本创建了该属的综合分布图，并为模式种（1869年，科普）建立了新模。对模式系列和分布在整个物种范围内的个体完成了细胞色素氧化酶I基因（COI）的分析，但发现变异很少。与2希厄尔和马雷克，2009年）一样，是该属仅有的成员。
