FIGURE 4 in Allocation of Salamandra auriculata Holbrook, 1838, with a new species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Atlantic Coastal Plain
FIGURE 4. Paratype (AMNH A-193889/RAP2294) of Desmognathus valtos. Specimen is a small adult (41.2 mm SVL) showing the same diagnostic features as the holotype, with more prominent dorsal color-pattern and lateral white flecking or speckling that is characteristic of younger individuals, with the latter extending noticeably onto the dorsal surfaces.
FIGURE 3 in Allocation of Salamandra auriculata Holbrook, 1838, with a new species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Atlantic Coastal Plain
FIGURE 3. Paratype (NCSM 108360/RAP2289) of Desmognathus valtos. Specimen is a juvenile or small adult (32.1 mm SVL) showing the same diagnostic features as the holotype, with more prominent dorsal color-pattern and lateral white flecking that is characteristic of younger individuals.
FIGURE 1 in Allocation of Salamandra auriculata Holbrook, 1838, with a new species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Atlantic Coastal Plain
FIGURE 1. Linear morphometric analysis of MNHN 0.4675, the lectotype of Salamandra auriculata Holbrook, 1838. Shown are the 75 scores and overall densities on the first linear-discriminant axis (a), the assignment probabilities for each specimen (b), a boxplot of the highest-loading trait with significant median difference (AG~SVL; c), and a map of the samples (d) with type localities indicated by triangles. We estimate strong support for allocation of the specimen and name to the Desmognathus auriculatus A lineage of northern Florida, southern Georgia, and southern Alabama. This necessitates a new name (D. valtos) for the D. auriculatus B/C lineage from the Atlantic Coastal Plain of the Carolinas.
FIGURE 19 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 19. Live photograph of two large adult male Desmognathus balsameus (RAP2826–7) in combat (a), found in situ under a log in the understory of a coniferous forest (b) near Bear Pen Gap (NC: Jackson; ~1670m ASL). No females were observed nearby, suggesting a possible territorial nature for the interaction. Both individuals show overall darkened adult coloration with few if any discernable color-pattern remnants. Adult Eurycea cf. wilderae and Plethodon metcalfi were found under similar logs, and D. wrighti is known from the site (Pyron et al. 2022c). The encounter occurred at ~1000h on 24 July 2022 and was found by M.A. Seldes. Photos by RAP.
FIGURE 13 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 13. Photographs of two adult Desmognathus adatsihi (a: RAP2818; b: RAP2820) in life, from the paratype locality on Rough Ridge (NC: Haywood). Photos courtesy of M.A. Seldes.
FIGURE 16 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 16. The holotype (AMNH A-193885/RAP0650) of Desmognathus balsameus from Bubbling Spring Branch (NC: Haywood), ~1530m ASL. This adult specimen (43mm SVL) has a relatively dull dorsal color-pattern partially obscured by ontogenetic darkening, common in this species. Photos by RAP.
FIGURE 10 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 10. Paratype (USNM 596063/RAP0890) of Desmognathus adatsihi from Cataloochee Balsam (NC: Swain) in life, photo courtesy of T.W. Pierson. This brilliantly colored erythristic morph and its xanthic counterpart are infrequently observed, primarily on Cataloochee Balsam near the type locality, but also very rarely on Clingmans Dome in the Smokies (Fig. 14a) and Waterrock Knob in the Plott Balsams (S. G. Tilley, pers. comm.). A similar specimen from near the type locality was mislabeled as D. imitator by Dodd (2004).
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 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
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. Photos courtesy of M.A. Seldes (UGA).
FIGURE 2 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains

Note overall "mountain" dusky phenotype with elongated, round tail, despite Coastal Plain origin of these populations. Photos in dorsal (a) and ventral (b) views courtesy of the NMNH.
FIGURE 1 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 1. Holotype (USNM 128007, field tag J.C.N. 1001) of Desmognathus ocoee Nicholls, 1949 from "the surface and in crevices of cliffs at Ship's Prow Rock, in Ocoee Gorge, beside U.S. Highway 64, nine miles airline west of Ducktown, in Polk County, Tennessee," collected 14 November 1948 by J.C. Nicholls, Jr. Note prominence of offset paired larval spots on the dorsum. Photos in dorsal (a) and ventral (b) views courtesy of the NMNH.
FIGURE 20 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 20. Live specimens of Desmognathus ocoee Nicholls, 1949 in lateral views (a, b) from the isolated Cumberland Plateau (TN: Marion) population (ocoee H), west of the Tennessee River close to the southernmost populations of D. abditus (see Drukker et al. 2018). Note the relatively prominent dorsal keel on the distal portion of the tail, and the indistinct or uniform, mostly brownish color-pattern. Photos courtesy of S. Drukker (Sewanee).
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 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
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).
