历史上，三种专性洞穴栖息的 Orconectes 物种组成了美国东南部坎伯兰高原沿线的一个组合，包括 Orconectes australis（有两个亚种，australis 和 packardi）、O. incomptus 和 O. sheltae。利用来自三个线粒体基因（细胞色素氧化酶亚基 I (COI)、12S 和 16S）的遗传数据，我们提供了除 O. sheltae 之外的四个神秘谱系的证据。 Orconectes australis 的亚种代表具有非姐妹系统发育关系的不同分类单位，并且每个亚种都将被视为单独的物种。巴里小龙虾 (Orconectes) barri 是一种地下小龙虾新种，少量分布于肯塔基州 - 田纳西州边界附近的密西西比石灰岩中。该物种是在之前对阿巴拉契亚山脉南部进行彻底采样的系统发育地理学调查中发现的。此外，我们还为每个物种分配遗传条形码（COI 序列）和保护状态，以用于管理指导和新发现种群的识别。
Historically, three obligate cave-dwelling species of Orconectes comprise an assemblage along the Cumberland Plateau of the southeastern United States, including Orconectes australis (with two subspecies, australis and packardi), O. incomptus, and O. sheltae. Using genetic data from three mitochondrial genes (cytochrome oxidase subunit I (COI), 12S, and 16S), we present evidence for four cryptic lineages excluding O. sheltae. The subspecies of Orconectes australis represent distinct taxonomic units with non-sister phylogenetic relationships and will be each recognized as separate species. Orconectes (Orconectes) barri is a new species of subterranean crayfish with a small distribution around the Kentucky - Tennessee state border in Mississippian limestone. This species was uncovered during a previous thoroughly-sampled phylogeographic survey of the southern Appalachians. Additionally, we assign genetic barcodes (COI sequences) and conservation status to each species for management direction and identification of newly discovered populations.
