FIGURE 2 in Allocation of Salamandra auriculata Holbrook, 1838, with a new species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Atlantic Coastal Plain
FIGURE 2. Holotype (MNHN 2021.0131/RAP0955) of Desmognathus valtos. Specimen is an adult (53.1mm SVL), possibly a female based on apparent lack of mental gland and lack of peramorphic or hypertrophied jaw musculature. The holotype exhibits the diagnostic greenish-grey ground color with a reddish-orange dorsal wash, orangish stripe with indistinct margins on the dorsal surface of the tail, yellowish or orangish portholes on the lateral surfaces in three rows, and granular ventral color-pattern with clusters of xanthophores and melanophores interspersed with white flecks and speckles.
FIGURE 6 in Systematics of the Ocoee Salamander (Plethodontidae: Desmognathus ocoee), with description of two new species from the southern Blue Ridge Mountains
FIGURE 6. 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) isolated in life. Photos courtesy of T.W. Pierson; specimens not to scale.
FIGURE 3 in A systematic revision of the Shovel-nosed Salamander (Plethodontidae: Desmognathus marmoratus), with re-description of the related D. aureatus and D. intermedius
FIGURE 3. An adult (~58mm SVL) specimen (USNM 596935/RAP2886) of Desmognathus marmoratus from Glade Creek (WV: Raleigh), isolated on white (a) and black (b) backgrounds in dorsolateral view. Note the smaller, stockier body and indistinct silvery-gold lichenous dorsal markings. This isolated population in the New River Gorge occurs ~120 airline km away from the nearest known sites in the Upper Tennessee drainage of Virginia (Fig. 1).
FIGURE 4 in A systematic revision of the Shovel-nosed Salamander (Plethodontidae: Desmognathus marmoratus), with re-description of the related D. aureatus and D. intermedius
FIGURE 4. Linear discriminant analysis of 142 samples from the four species of Shovel-nosed Salamanders (a), based on 17 measurements taken from vouchered specimens (Appendix S1), with a boxplot for Axilla-Groin length (AG; b) and Snout-Gular Length (SG; c) scaled by size for each species, selected from the heaviest loadings of the 16 variables indicated on a relative scale as grey rays in (a). Non-overlapping notches indicate significant median differences.

FIGURE 9. Sampling localities for Desmognathus quadramaculatus, symbols match those in Fig. 8.
