Pseudoeurycea lineola
Mexican Slender Salamander
Subgenus: Pseudoeurycea
family: Plethodontidae
subfamily: Hemidactyliinae
Taxonomic Notes: This species was long placed in Lineatriton, which molecular systematic analyses show to be deeply nested within one of two major clades of Pseudoeurycea, close to the generotype of that genus, P. leprosa.

Description
Lineatriton lineolus is a very slender salamander that is found primarily on dry land. The species can grow up to 38 mm SVL and 128 mm TL. In adult individuals, the tail is cylindrical and usually twice as long as the body and head. The front and forelimbs are short, with partially webbed hands and feet. This species has a rounded snout and stalked tongue.

L. lineolus can be distinguished from other wormlike salamanders by the long, narrow vertebrae it has. In all, the body contains fifteen elongated vertebrae.

This species is usually a dull black, with paler coloration marking the sides, (Dunn 1926) although Shannon and Werler (1955) have documented living specimens that were uniformally lead gray (Tanner and Dundee, 2000).

Distribution and Habitat

Country distribution from AmphibiaWeb's database: Mexico

L. lineolus can only be found in perennial evergreen tropical forests in central Veracruz, Mexico (Pelcastre-Villafuerte and Flores-Villela 1992). Although the distribution of this species is below the cloud forests, it extends up to 1250 m. These areas recieve the most precipitation in Veracruz. Within these habitats, L. lineolus is found under stones, leaves, and trash on plantations, as well as in rotten logs (Tanner and Dundee 2000).

Comments
Etymology:

Lineatriton comes from the Latin words "linea," which literally translates as "feminine," and "triton," the name of the Roman sea god. "Linea" refers to the slender appearance of the salamander. The species name, lineola, is also from "linea," but in this context, it refers to the thin vertebral line some individuals have (Tanner and Dundee 2000).
