Pseudoeurycea unguidentis
Pseudoeurycea unguidentis is a salamander in the family Plethodontidae (order Caudata), recorded as Critically Endangered.
Appearance
Pseudoeurycea unguidentis measure about 6.4 cm (2.5 in) in snout–vent length and 14–15 cm (5.5–5.9 in) in total length. It has a brown and gray middorsal region, lacking a delineated middorsal stripe.
Range and habitat
It is endemic to northern Oaxaca, Mexico, where it is known from its type locality, Cerro San Felipe in the Sierra Madre de Oaxaca, and some other mountains, although the identity of animals from these other locations is uncertain. The species' natural habitat is pine-oak and fir forests. It is a semi-arboreal species commonly found under logs.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Breeding
Salamanders hide under logs, in seeps, or in caves. They do not commute across a dry valley.
Eggs and damp skin make amphibians quick to vanish from a drained wetland or a forest stripped of litter.
In crisis
The reasons for the decline are unknown but probably involve habitat loss and modification. Also climate change and chytridiomycosis may have played some role.
Salamanders disappear when seeps are capped, caves are disturbed, or a pathogen moves through a mountain range.
