Coloration and color pattern. Like many cambarid crayfishes, L. dalyae sp. nov. exhibits a notable ontogenetic shift in its coloration and color pattern (MGG, personal observation).

Large adult specimens resemble the holotype and exhibit the most striking coloration found in this species ( Figure 1 View FIGURE 1 ). The background coloration of the cephalothorax and chela of these large specimens is predominantly golden. The dorsal surface of the cephalothorax is darker than the lateral surfaces, which are subtly mottled. The legs of large adults are a light amber or cream color. The background coloration of the abdomen is typically darker than the cephalothorax, ranging from ocher to bronze. The background color of the crayfish is complemented by polychromatic highlights throughout the body. The dorsal surface of the carpus and merus are highlighted in shades of turquoise and emerald. The surfaces of the telson and rami of clean (i.e., recently molted) specimens are blue with white speckles. Much of the crayfish is highlighted in a ruby red color, including the tips of the chela, the tubercles and spines of the chela, merus and carpus, and the margins of the antennal scales, rostrum, postorbital ridge, pereiopods 2–5, abdomen, telson and uropods. The dorsal side of the cephalothorax and abdomen is adorned by a single longitudinal gladiate stripe that is typically yellow. Lastly, the dorsal side of the cephalon is adorned by a diamond-shaped pattern formed anteriorly by the ruby red highlights of the rostral margins and postorbital ridge and posteriorly by two ruby red to orange diagonal lines running from the distal ends of the postorbital ridge to a convergence point just anterior to the cervical groove.

The coloration and color pattern of young adult specimens differs slightly from adults ( Figures 3 View FIGURE 3 , 4 View FIGURE 4 ). Firstly, these specimens exhibit more pronounced mottling on their cephalothoraxes and abdomens. In addition, the background coloration of these younger specimens is less vibrant, ranging from burnt orange to olive. These specimens have more conspicuous turquoise and emerald highlights on their merus, carpus and chela than large adults. Lastly, the diamond-shaped pattern on the cephalon is sometimes less clearly delineated in these specimens, but it is typically still present.

Juvenile specimens are the darkest and most mottled specimens of the species. The background color of their entire body including the chela ranges from bronze to brown. They have conspicuous mottling on the lateral surfaces of the abdomen and cephalothorax which is of a muted goldenrod color. These specimens still bear characteristic markings of the species, including the dorsal longitudinal gladiate stripe, which is also a goldenrod color, and the diamond-shaped pattern on the cephalon. Lastly, these specimens have similar, albeit more muted, ruby red highlights on the margins of somites throughout the body.

Size. The largest L. dalyae sp. nov. that we have examined is a Form I male from Prentiss County, Mississippi that measures 53.4 mm carapace length (CL). The average ± standard deviation size of specimens that we examined was 43.0 ± 5.2 mm CL for Form I males, 38.4 ± 4.5 mm CL for Form II males, and 42.4 ± 3.5 mm CL for Females. The smallest Form I male that we examined measured 33.9 mm CL; however, Miller et al. (2014) recorded collecting a Form I male specimen measuring 27.4 mm CL.

Variation. There is a moderate amount of morphological variation across the range of L. dalyae sp. nov. We have examined specimens from Tennessee with lanceolate rostrums lacking clearly delimited acumens and others with rostral margins that remain thickened and entire to the tip of the acumen. One specimen from Pike County, Alabama has distinctly concave rostral margins. Some specimens from across the range have a very slight depression at the tip of the central projection that one might label as a subapical notch, but we hesitate to do so as this feature is considerably more subtle than the deep and conspicuous subapical notch found in some other members of the genus (see key below). We have also seen variation across the species’ range in the distal end of the mesial process, which is occasionally tipped with one or more minute, finger-like tubercles, sometimes oriented laterally creating a fork. In some specimens, the lateral-most of the 2 bulbous tubercles on the articular rim opposite the ventral base of the dactyl is topped with a sharp spine oriented distally. One specimen from Lee County, Georgia exhibited an impressive and highly unusual 23 subpalmar tubercles, and a specimen from Walton County, Florida bore uncharacteristically long and thin chelae that did not appear to have been regenerated. Lastly, two specimens from Davidson County, Tennessee have remarkably thin antennal scales.

As mentioned above, much of the color variation found in L. dalyae sp. nov. is ontogenetic in nature; however, there appears to be a fair amount of color variation across this species’ range. Particularly noteworthy are specimens from Alabama whose background colors are bright green or orange, rather than the usual gold (Guenter A. Schuster, personal communication). Despite this color variation, these specimens were still recognizable by their longitudinal gladiate stripe and diamond-shaped pattern on the cephalon, suggesting that the color pattern of this species is more characteristic than the color itself.

Disposition of Types. The holotype, morphotype and allotype are deposited in the OSUMC (OSUMC 10855– 10857). Paratypes are deposited in the NCSM (NCSM 90130–90132).

Type locality. We collected the holotype and allotype from the banks of Big Richland Creek, a tributary of the Tennessee River in Humphreys County, Tennessee (36.1576° N, 87.8203° W). Most of the burrows at this site were within 1 meter of the stream channel and relatively shallow. These burrows were surrounded by dense ground vegetation and occasional young trees. The soil at this site was primarily clay mixed with a small amount of sand and pebbles.

We collected the morphotype and paratypes from burrows in and above the floodplain of Hurricane Creek, a tributary to the Duck River in Humphreys County, Tennessee (35.9823° N, 87.8148° W). The burrows that we excavated at this site were up to 10 m away from the stream channel and surrounded by ground vegetation (including a large amount of poison ivy) and mature trees. The terrain beyond the floodplain of Hurricane Creek at this site is steeply sloped causing some burrow entrances to be over 2 m above the water table and therefore particularly difficult to collect crayfishes from. The soil at this site was mostly clay loam with some sand.

Range. This species is widely distributed across the southeastern United States, having so far been found in Alabama, Florida, Georgia, Mississippi and Tennessee ( Figure 5 View FIGURE 5 ). The western limit of its range appears to be the Mississippi River, as we are not yet aware of any records of L. dalyae sp. nov. from Louisiana, Arkansas or Missouri. The eastern limit of this species’ range is less clearly defined; we have numerous samples of this species from the Florida panhandle and the Upper Coastal Plain in Georgia, but further sampling will be required to more thoroughly determine its range in these states. Similarly, the northern extent of the species’ range is unclear. It is found in West and Middle Tennessee, but we have not yet located it in East Tennessee or Kentucky. Kentucky is inhabited by a number of other Lacunicambarus species, including the closely-related L. polychromatus , so it is possible that competitive exclusion has prevented L. dalyae sp. nov. from expanding its range into this State. Similarly, East Tennessee is occupied by L. aff. thomai ( Jezerinac, 1993) and L. acanthura ( Hobbs, 1981) , and this region is also characterized by an increase in topographic relief and associated change in hydrology, to which L. dalyae sp. nov. may not be adapted. Overall, this species’ range does not correspond cleanly with any major drainage basin or ecoregion, but most of its range is within the confines of the South-Atlantic Gulf River Basin and the Southeastern Plains and Interior Plateau regions of the Southeastern USA Plains (sensu Wiken et al., 2011).

Specimens examined. We examined a total of 175 specimens from 31 counties in five States. See Table 3 View TABLE 3 for information on these specimens.

Conservation status. Lacunicambarus dalyae sp. nov. is widely distributed throughout the southeastern United States and common in appropriate habitat. It appears to persist amidst a moderate amount of anthropogenic habitat degradation, as evidenced by specimens collected from burrows in roadside ditches and urban lawns. We suggest that it be considered Currently Stable following the American Fisheries Society’s Endangered Species Crayfish Subcommittee criteria (Taylor et al., 2007) and of Least Concern following the IUCN criteria ( IUCN, 2012), but also recommend that potential threats to this species, including from pet trade collectors, be preemptively examined.

Life history notes. A detailed life history of L. dalyae sp. nov. in Alabama has previously been published ( Miller et al., 2014). Amongst their findings, Miller et al., 2014 reported that mating of L. dalyae sp. nov. occurs in burrows during autumn or winter, with females extruding up to 171 eggs at the end of that same winter. Our examination of specimens largely corroborates this timing except for a single gravid female from Alcorn County, Mississippi that was collected on August 27 th, 1936. Overall, this phenology is similar to what has been documented for other Lacunicambarus species (e.g., Fitzpatrick, 1978; Thoma et al., 2005; Glon et al., 2019). In addition, Miller et al., 2014 found that juvenile L. dalyae sp. 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. We do not have a reliable way of aging our specimens, but we expect that the maximum lifespan of this species could be as much as twice this minimum lifespan estimate based on our observations of other Lacunicambarus species (e.g., Glon et al., 2019).

Ecological notes. Lacunicambarus dalyae sp. nov. is a primary burrowing crayfish typically found burrowing in alluvial soils of stream floodplains. Populations of this species are also frequently found burrowing in anthropogenically altered habitats like roadside ditches, the banks of ponds, and urban lawns. Like most of its congeners, this species excavates moderately complex burrows that consist of one or more surface openings ( Miller et al., 2014 found a range of 1–5 with a mean of 2.1) leading to tunnels that converge into a central tunnel approximately 30-50 cm below the surface. The depth attained by the central tunnel is largely dependent on the depth of the water table and substrate but can be greater than 2 m for adults. Depending on the time of year and weather conditions, burrow openings may be open or plugged, and one or more of these openings may be topped by a conspicuous chimney made of mud pellets excavated from the burrow.

Like its congeners and most other cambarid crayfishes, L. dalyae sp. nov. appears to be an opportunistic omnivore ( Reynolds et al., 2013). We have not collected dietary data for this species in situ but individuals that we have kept in captivity have thrived when fed a diet consisting of a mixture of foods including leaf detritus, live invertebrates, and shrimp- and spirulina-based commercial fish foods.
