Data from: A new species of spottail darter endemic to the Clarks River in Kentucky and Tennessee (Percidae: Etheostomatinae: Etheostoma)
<p><em>Etheostoma xanthovum</em>, the Clarks Darter, is described as a new species endemic to the Clarks River in Kentucky and Tennessee, USA. <em>Etheostoma xanthovum</em> was previously delimited as <em>Etheostoma oophylax</em>, the Guardian Darter, based on morphological trait data. Subsequent to the description of <em>E. oophylax</em>, molecular phylogenetic analyses consistently resolved specimens from the Clarks River system and <em>E. chienense</em>, the Relict Darter, as sister species, which together formed a sister clade to all other sampled populations of <em>E. oophylax</em>. Our analyses of morphological traits, mitochondrial DNA (mtDNA), and genomic sampling using double digest restriction-site associated DNA (ddRAD) sequencing support the distinctiveness of <em>Etheostoma xanthovum</em>. Morphologically, <em>Etheostoma xanthovum</em>, differs from <em>Etheostoma oophylax</em> in the number of dorsal fin rays (12 versus 11), anal fin rays (8 versus 7), and in the number of scale rows around the caudal peduncle (21.8 versus 20.37). <em>Etheostoma xanthovum</em> does not share mtDNA haplotypes with <em>Etheostoma oophylax</em> or <em>Etheostoma chienense</em>. Phylogenomic analysis of an average of 28,448 ddRAD loci per sampled specimen resolves <em>Etheostoma xanthovum</em> and <em>Etheostoma chienense</em> as sister species, and assessment of genomic divergence supports the hypothesis that each of these two species represents a distinct and independently evolving lineage. In addition, we report a range extension of <em>Etheostoma oophylax</em> in the Obion River system, a direct tributary of the Mississippi River. </p>

FIGURE 11 in Integrative taxonomy reveals two new narrowly-endemic crayfish species (Decapoda: Cambaridae) from the Yadkin River Basin in western North Carolina, USA
FIGURE 11. Hypothesized passive margin escarpment evolution (PMEE) time series of the Stony Fork watershed (figure concept adapted from Prince et al. 2010). i) The initial Eastern Continental Divide (ECD) demarcated the higher-gradient, moderate elevation Yadkin River basin and moderate-gradient, higher elevation New River basin; the basins did not share an ancestral Cambarus species. ii) Erosion along the higher-gradient eastern slope of the ECD (dotted line) captured the headwaters of a historic New River Basin stream, bringing ancestral C. aff. robustus into the Yadkin basin and forcing a downstream retreat of ancestral C. species C. iii) Additional erosional events (dotted lines) pushed the ECD further inland and demarcated extant interior basin species from Atlantic Slope species; Cambarus lapidosus is isolated from C. aff. robustus in the Stony Fork headwaters by the extant ECD and from downstream C. species C by a natural waterfall barrier.

FIGURE 1. Terrain map of collection sites and the known ranges of Cambarus lapidosus and C. burchfielae in the Blue Ridge mountains of western North Carolina. Red triangles represent genetic samples and specimens of C. lapidosus used in this study; the red star indicates the type locality and red shading represents the known range (one HUC12) of the species. Orange diamonds represent genetic samples and specimens of C. burchfielae used in this study; the orange star indicates the type locality and orange shading represents the known range (two HUC12s) of the species. Open circles indicate genetic sampling locations where neither focal species was detected during this study. Closed circles represent historic sampling locations (combined NCSM and NCWRC records) where specimens of the target species were not identified. Black lines represent major drainage boundaries (HUC6), pink-bordered line indicates the Eastern Continental Divide. Green shading represents conserved or protected lands, dark-gray shading represents developed areas. Inset: the boundaries of North Carolina's major river basins and bordering states; gray shading denotes the Yadkin-PeeDee basin. (Maps created in QGIS v3.1.2).
