Plethodon serratus
Grobman, 1944
Washington Co., Missouri. Spring 1976.
When I first encountered this species they were considered to be Plethodon cinereus. They have a spotty and scattered distribution, and since then I’ve found P. serratus in several places in the southern Missouri Ozarks, including Mingo Swamp, where these photos were taken.
My Flickr album for this species is here.
