“…Likewise, this species' range does not seem to correspond with any particular ecoregion, extending over parts of the Interior River Valleys and Hills, Interior Plateau, Southeastern Plains, and Mississippi Valley Loess Plains (Wiken et al 2011). This general range may suggest that this species is capable of dispersing via large streams and rivers like other species in this genus and is therefore not restricted by drainage basin boundaries (Helms et al 2013;Miller et al 2014;Glon et al 2018). Alternatively, this species' contemporary range may be a remnant of a paleodrainage, as it corresponds well with the pre-Holocene Old Ohio River whose flow was altered as glaciers advanced southward during the Pleistocene (Strange & Burr 1987;Kozak et al 2006).…”

Lacunicambarus diogenes (Girard 1852) was, until recently, considered to be one of the most widely distributed North American crayfish species, occurring in 31 U.S. States and one Canadian province east of the North American Rocky Mountains. Glon et al. (2018) investigated this claim and found that L. diogenes sensu lato was actually a species complex. The authors redescribed L. diogenes and restricted its range to the Atlantic Coastal Plain and Piedmont ecoregions of eastern North America. In doing so, they also revealed the existence of several probable undescribed species of Lacunicambarus that were previously considered to be L. diogenes. Here, we use morphological and molecular techniques to distinguish and describe one of these species: Lacunicambarus chimera sp. nov., a large primary burrowing crayfish found in parts of the Lower Mississippi, Ohio, Tennessee and Upper Mississippi River Basins. Lacunicambarus chimera is morphologically similar to L. diogenes, from which it can be distinguished by the greater number of spines on the ventrolateral margin of its merus, its wider antennal scale terminating in a short spine, and the presence of a single longitudinal stripe on the dorsal side of its abdomen. We also provide an updated key to Lacunicambarus.

“…nov. are released and spend a period time in open water habitats before emerging to dig their first burrows in the banks or floodplain, which is a dispersal strategy that may contribute to the wide range of L. dalyae sp. nov. and other Lacunicambarus species (Helms et al, 2013;Clay et al, 2017;Glon et al, 2018). Based on their length-frequency histograms, Miller et al, 2014 suggested that the minimum lifespan of this species is 4 years.…”

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.

“…Thus accurate navigation from an aquatic environment to terrestrial burrowing habitat containing suitable soil, groundwater, and foraging conditions, as well as potential mates, is necessary to maintain population viability. Previous studies with C. diogenes suggest that isolated juveniles prefer clayey, floodplain soils over sandy, streamside soils for burrowing; in the presence of conspecific adults however, juveniles prefer adult burrowing locations irrespective of soil type (Grow 1982, Helms et al 2013a. In this study, we investigate further potential drivers of observed burrowing distributions by addressing the following questions:…”

“…Crayfish species vary in their capacity for burrowing and in their ultimate use of burrows (Hobbs 1981, Berrill and Chenoweth 1982, DiStefano et al 2009. Many burrowing crayfish species tend to exhibit strong spatial clumping, which is partly a function of abiotic factors such as local soil, hydrologic, and geomorphologic conditions (Grow 1982, Loughman et al 2012, Helms et al 2013a. However, the degree of connectivity between spatially segregated burrowing populations, and the specific cues and movement patterns used by these animals as they navigate the terrestrial landscape, is largely unknown.…”

“…Cambarus diogenes (Devil crayfish) is a burrowing crayfish widely-distributed alongside streams, rivers and ponds across Eastern North America (Grow 1981, Taylor et al 2007, Helms et al 2013a). It inhabits flood plains and seasonally flooded woodland areas, constructing elaborate burrow systems usually topped with well-constructed earthen mounds ("chimneys" see also Grow 1982, Helms et al 2013a). Female C. diogenes generally leave terrestrial burrows and enter nearby surface waters to release their young during winter and early spring (Hobbs 1981, Pflieger andDryden 1996).…”

Environmental cues contain critical information for individuals while searching for mates and suitable habitat. Crayfish have well-developed chemosensory abilities for detecting environmental cues in water; much less is known about these abilities on land. The Devil crayfish (Cambarus diogenes) is a burrowing crayfish often found in dense floodplain colonies as adults. Juveniles however are released in surface water and must navigate overland to burrow. Previous work demonstrates juveniles use cues from conspecific adults, and to a lesser extent, soil cues, for burrow site selection. Using mesocosms, we build on this by examining burrowing cues associated with (1) congeneric adults, (2) excavated burrow material and (3) other juveniles. In contrast to conspecific adults, cues provided by congeneric adults did not override cues associated with soil type. Similarly, juveniles burrowed closer to conspecific adult burrow mounds than to congeneric and human-built mounds. Juveniles also showed significant grouping behaviour in the absence of all other cues. These results suggest juvenile crayfish integrate multiple terrestrial cues for burrow site selection.
