Alberch's Mushroomtongue Salamander

Bolitoglossa alberchi is a large salamander for its genus, with females growing to a snout–vent length of 45.1–97.1 mm (1.78–3.82 in) and males reaching a snout–vent length of 59.4–69.6 mm (2.34–2.74 in). This boldly colored salamander has a black body, with two bands of grayish-green to yellowish chevrons running down the back. These chevrons often join each other across the spine, creating an irregular, complexly-patterned band punctuated by black patches. The snout and limbs are densely flecked with greenish-yellow. The underside is dark brown with whitish-yellow spots. The very long tail is usually black with large greenish-yellow blotches, sometimes giving it a ringed appearance, but only has fine flecks when regenerated.

Bolitoglossa alberchi is endemic to Mexico, where it has a disjunct range in the states of Veracruz, Chiapas, and Oaxaca. In Veracruz, it is known from the Caribbean slope of the Los Tuxtlas mountains. It also occurs in the Los Chimalapas mountains from far eastern Oaxaca to western and central Chiapas. The species largely inhabits relict lowland rainforest, woodland edge, and pastures. It is also known from plantations and banana farms, suggesting a tolerance of disturbed habitat, but is likely still dependent on forested habitat. The species is nocturnal.
