The Jewel Mudbug, Lacunicambarus dalyae sp. nov., is a large, colorful primary burrowing crayfish found in Alabama, Florida, Georgia, Mississippi and Tennessee. This species is most similar in appearance to the Paintedhand Mudbug, L. polychromatus, a species found across the Midwestern United States. The ranges of the two species overlap minimally, and they can be distinguished from each other based on several characters, the most notable of which is the much longer central projection of the gonopod in Form I and II males of L. dalyae sp. nov. relative to L. polychromatus. Like its congeners, L. dalyae sp. nov. is commonly found in burrows in the banks and floodplains of streams and is resilient to a moderate amount of anthropogenic habitat degradation, being occasionally collected from burrows in roadside ditches and urban lawns.
宝石小龙虾（Lacunicambarus dalyae sp. nov.）是一种大型、色彩斑斓的原生穴居小龙虾，分布于阿拉巴马州、佛罗里达州、佐治亚州、密西西比州和田纳西州。该物种在外观上与彩绘手小龙虾（L. polychromatus）最为相似，后者是一种分布于美国中西部的物种。这两个物种的分布范围极少重叠，并且可以根据几个特征相互区分，其中最显著的是宝石小龙虾（Lacunicambarus dalyae sp. nov.）I型和II型雄性个体的生殖肢中央突起比彩绘手小龙虾长得多。与同属其他物种一样，宝石小龙虾常见于溪流两岸和洪泛区的洞穴中，并且对一定程度的人为栖息地退化具有耐受性，偶尔也能在路边沟渠和城市草坪的洞穴中采集到。
