While sampling for the Rusty Gravedigger, Lacunicambarus miltus, Taylor et al. (2011) found one or more potentially undescribed burrowing crayfish species in the genus Lacunicambarus inhabiting the area between the Pascagoula River and Mobile Bay in southern Alabama and Mississippi. Molecular analyses by Glon et al. (2018) confirmed that samples from this area were genetically distinct from other Lacunicambarus crayfishes. These findings prompted a dedicated sampling trip in January 2020. We used morphological and molecular analyses to investigate the specimens we collected and, based on our results, we describe two new crayfish species: the Lonesome Gravedigger, L. mobilensis sp. nov. and the Banded Mudbug, L. freudensteini sp. nov. Lacunicambarus mobilensis sp. nov. is sister to the Rusty Gravedigger, L. miltus, while L. freudensteini sp. nov. is sister to the Painted Devil Crayfish, L. ludovicianus. Both new species are currently known from a small number of sites in southern Alabama and Mississippi and may require conservation attention. In addition, we provide an updated key to Lacunicambarus crayfishes that includes these new species.
在对铁锈掘墓者螯虾（Lacunicambarus miltus）进行采样时，泰勒等人（2011年）在阿拉巴马州南部和密西西比州的帕斯卡古拉河与莫比尔湾之间的区域发现了一种或多种可能未被描述的穴居螯虾物种，它们属于Lacunicambarus属。格隆等人（2018年）的分子分析证实，该区域的样本在基因上与其他Lacunicambarus螯虾不同。这些发现促使在2020年1月进行了一次专门的采样之旅。我们使用形态学和分子分析来研究我们收集的标本，并根据结果描述了两种新的螯虾物种：孤独掘墓者螯虾（L. mobilensis sp. nov.）和带状泥虫螯虾（L. freudensteini sp. nov.）。新物种Lacunicambarus mobilensis sp. nov.是铁锈掘墓者螯虾（L. miltus）的姐妹物种，而L. freudensteini sp. nov.是彩绘魔鬼螯虾（L. ludovicianus）的姐妹物种。这两个新物种目前仅在阿拉巴马州南部和密西西比州的少数地点被发现，可能需要加以保护。此外，我们提供了一份包括这些新物种的Lacunicambarus螯虾的更新检索表。
