A morphological study comparing Desmognathus welteri with D. monticola and D. fuscus was conducted. The structure of two characters, toe friction pads and jaw teeth, were assessed. Darkened toe friction pads were found in D. welteri and D. monticola, but were absent in D. fuscus. In contrast, D. welteri and D. fuscus share similar jaw dentitions (blunt-crowned teeth) as opposed to the dentition of D. monticola (piercing, pointed teeth).
