The Forest Sharp-tailed Snake was recognized as a separate species from the Common Sharp-tailed Snake (Contia tenuis) in 2010. While these two species closely resemble one another, Forest Sharp-tailed Snakes can be identified by their long tails which have 43-58 subcaudal scales. This secretive species limits most of their activity to the rainy season, preferring to stay underground during dry conditions. Forest Sharp-tailed Snakes occur in southwest portion of the Oregon, where they select mesic environments and can be found in shaded forest habitats and mixed woodlands.
