Firschein's False Brook Salamander

Pseudoeurycea firscheini was described based on four specimens of unspecified sex, including the holotype measuring 47 mm (1.9 in) in snout–vent length and a juvenile measuring 23 mm (0.91 in) in snout–vent length and 47 mm (1.9 in) in total length. The adults have small, lichen-like light spots on the tail. The sides and the underparts of the body are almost black. The hind legs are relatively large. The fingers are less than half-webbed, whereas the slender toes are about one-third webbed.

Its natural habitats are pine-oak forests and lower cloud forests at elevations of 1,900–2,200 m (6,200–7,200 ft) above sea level. The type series was collected in water-filled bromeliads growing on trees at heights of 2.1–6.1 m (7–20 ft) above ground, and it appears to require the presence of abundant bromeliads growing on mature trees in its habitat. The dependence of Pseudoeurycea firscheini on large bromeliad-covered trees makes it susceptible to habitat loss caused by expanding agriculture and human settlements and by wood extraction. The species might be present in the Cañón del Río Blanco National Park, but this has yet to be confirmed. Mexican law protects it under the "Special Protection" category.
