Thorius infernalis (Atoyac minute salamander)

Wikipedia Abstract

Thorius infernalis (common name: Atoyac minute salamander) is a species of salamander in the family Plethodontidae. It is endemic to Mexico where it is only known from its type locality in the Sierra Madre del Sur in central Guerrero. Its natural habitat is riparian vegetation along hillsides, presumably in forest. It is only known from two specimens, and it has not been seen since early 1980's. Much of the potential habitat is already converted into coffee plantations. It is threatened by habitat loss caused by expanding agriculture and human settlements.

EDGE Analysis

The Atoyac minute salamander is a small species, growing to less than 40 mm in total length. It was formerly found in stream-side vegetation, living under logs and bark, but its habitat has largely been converted to coffee plantations and the remaining area is under threat of further human encroachment. It has not been seen since the early 1980s and may already be extinct.
