FIGURE 11 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 11. Paratype (USNM 596064/RAP0891) of Desmognathus adatsihi from Cataloochee Balsam (NC: Swain) in life, photo courtesy of T. W. Pierson. This partially spotted morph is the only color pattern that is likely to be confused with D. imitator, but the spots are more contiguous, particularly towards the tail, with an overall lighter ground color (see Tilley 2000).
FIGURE 9 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 9. The type locality of Desmognathus adatsihi on Cataloochee Balsam, Great Smoky Mountains National Park (NC: Swain), ~1650m ASL. The habitat is classic "spruce-fir" forest. The type series were captured under rocks and logs in the foreground. Photo courtesy of T.W. Pierson.
FIGURE 5 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 5. Holotype (USNM 596065/RAP0892) of Desmognathus adatsihi from Cataloochee Balsam, Great Smoky Mountains (NC: Swain) in life, photo courtesy of T.W. Pierson (KSU). This solidly striped morph is most commonly representative of Smokies populations and is distinguishable from D. imitator by the straight and well-defined borders of the uniformly colored dorsal stripe.
FIGURE 21 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 21. Photographs of Desmognathus cf. ocoee from Horse Cove, Rich Mountains (GA: Gilmer) in life (a: one of the specimens in the series MCZ A-143377–86 collected 29 June 2003; photo courtesy of C.D. Camp, Piedmont) and preservative (RAP2715, collected 14 July 2022) in dorsal (b) and ventral (c) views. The paired dorsal spots on the trunk and tail of the latter specimen were brighter and more yellowish overall in life. The phylogenetic and taxonomic affinity of this population is unknown.

FIGURE 12. Comparison of large, darkened adult males (based on elongated snouts and peramorphic jaw musculature) of Desmognathus adatsihi (a: RAP2816; Rough Ridge, NC: Haywood) and D. balsameus (b: RAP2827; Bear Pen Gap, NC: Jackson; Fig. 16a) in life, showing the similar overall melanic coloration taken on with age.

FIGURE 7 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 7. Paratypes (USNM 596063–4/RAP0890–1; a,b) and holotype (USNM 596065/RAP0892, c) of Desmognathus adatsihi from Cataloochee Balsam, Great Smoky Mountains (NC: Swain) in dorsal view in preservative, approximately to scale with tick marks in mm. Photos by RAP.
FIGURE 15 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 15. An aberrant specimen (RAP0908) of Desmognathus adatsihi from Rough Ridge (NC: Haywood) in life on isolated (a) and natural (b) backgrounds. In contrast to the regularly encountered erythristic and xanthic morphs, we hypothesize this individual to be a singular mutant, probably leucistic, rather than a form which occurs with any frequency in the population. Photos courtesy of T.W. Pierson.
FIGURE 14 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 14. Comparison of small adult Desmognathus adatsihi (a: not collected; Clingmans Dome, TN: Sevier/NC: Swain) and exceptionally large (54mm SVL) adult D. balsameus (b: RAP2831; Lost Knob, NC: Jackson) in life, showing the dramatic possible differences in body form and coloration. Photos courtesy of M.A. Seldes.

FIGURE 17. Comparative specimens of Desmognathus balsameus in preservative in dorsal (a, c) and ventral (b, d) views, showing dorsal stripe with wavy or undulating edges (RAP0979; Black Balsam Knob, NC: Haywood; a, b), and the early ontogenetic stage of this pattern with more distinct paired spots (RAP0990; Burnette Cove Creek, NC: Haywood; c, d).
FIGURE 4 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 4. Map of the five species considered by our taxonomy from genetically verified recent localities (RAP collection; Anderson & Tilley 2003; Beamer & Lamb 2020; Karlin & Guttman 1986; Kozak et al. 2005; Means et al. 2017; Pyron et al. 2022c; Tilley 2000; Tilley et al. 1978, 2008; Tilley & Mahoney 1996). We include apalachicolae A2 and ocoee E within our concept of D. ocoee, for which the nominotypical lineage is ocoee F/G/H. Note that some individuals from these populations are admixed between one or more species, and hybrid zones exist between phylogeographic lineages within D. ocoee and D. perlapsus, primarily at the geographic margins where each adjacent lineage contacts its neighbor. Type localities are indicated with triangles, the population of unknown affinity from Horse Cove (GA: Gilmer; Fig. 21) is indicated with a gray dot, and the potential Cohutta populations are indicated with a "?."
FIGURE 8 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 8. Paratypes (USNM 596063–4/RAP0890–1; a,b) and holotype (USNM 596065/RAP0892, c) of Desmognathus adatsihi from Cataloochee Balsam, Great Smoky Mountains (NC: Swain) in ventral view in preservative, approximately to scale with tick marks in mm. Photos by RAP. Dorsal pattern of erythristic morph (a) shows significant intrusion onto ventral surfaces, compared to the relatively immaculate spotted and striped morphs (b, c).

FIG. 3. Estimated probability of occupancy (black bars) and detection (gray bars) for salamander species along Spavinaw Creek, Benton County, Arkansas, USA. Estimates are based on three 10 min nocturnal visual surveys per site. Error bars represent 95% credible intervals.
FIG. 5 in Distribution and Abundance of Introduced Seal Salamanders (Desmognathus monticola) in Northwest Arkansas, USA
FIG. 5. Effect of microhabitat PC1 on occupancy probability of E. lucifuga and E. longicauda along Spavinaw Creek. Solid lines represent the mean relationship between PC1 scores and occupancy probability and dashed lines are the 95% credible intervals for estimates of the covariate effect.
FIG. 2 in Sexual Isolation between Two Sympatric Desmognathus in the Gulf Coastal Plain
FIG. 2. Joint isolation coefficients from published studies of crosses between species of plethodontids. Joint isolation (JI) coefficients for insemination from crosses between allopatric (black) and sympatric (gray) taxa are represented as a histogram. Results from this study (JI ¼ 1.21) between sympatric D. aff. auriculatus and D. conanti (SL) are indicated with a patterned fill. Previously published studies represented in this figure include Verrell (1989b, 1990a, 1990b), Verrell and Tilley (1992), Uzendoski and Verrell (1993), Arnold et al. (1996), Herring and Verrell (1996), Kozak (2003), and Mabry and Verrell (2004).
FIG. 1 in Sexual Isolation between Two Sympatric Desmognathus in the Gulf Coastal Plain
FIG. 1. Collection localities in the Pascagoula and Pearl river drainages. The inset includes a portion of the Gulf Coastal Plain with state names abbreviated and the study area enclosed within a gray square. White and gray circles mark locations from which only D. aff. auriculatus or D. conanti (SL) were collected, respectively. The black square marks a locality from which both species were collected syntopically.
