Comprehensive DescriptionRead full entry
A small terrestrial salamander. The sides are dark brown to black with white flecks, and a mid-dorsal stripe varies from red to chestnut. Black pigment in the dorsal stripe may be small spots or chevrons (^). The stripe runs from the head to the tip of the tail. The venter is salmon-pink or reddish with black specks. The outer toe of the hind foot is small. Adults reach sizes of 35-55 mm snout to vent length (75-100 mm total lengh). Females reach larger adult sizes than males (50 vs. 45 mm SVL). Modal number of costal grooves is 15. Males lack mental glands. Hatchlings are 17-18 mm SVL (Brodie 1970; Leonard et al. 1993; Petranka 1998).
Plethodon larselli may be distinguished from other Pacific Northwest species of Plethodon by the reddish coloration of the venter, the dorsal stripe which extends to the tail tip, and the small size of the outer toe on the hind feet (Stebbins 1985; Leonard et al. 1993).
