Pseudoeurycea lineola, commonly known as the Veracruz worm salamander or Mexican slender salamander, is a species of salamander in the family Plethodontidae. It is endemic to the Sierra Madre Oriental near Cuautlapan, in the east-central Veracruz, Mexico, at elevations of above sea level. Molecular evidence suggests that it consists of two distinct species. It was the type species of genus Lineatriton.
