Description
Thorius aureus is a species of minute lungless salamander belonging to the family Plethodontidae. Members of the genus Thorius are among the smallest terrestrial salamanders, typically measuring less than 30 mm in total length. As a plethodontid, T. aureus lacks lungs and respires cutaneously and buccally. The specific epithet aureus derives from Latin, meaning “golden,” and may refer to coloration observed in the holotype or type series.
Distribution and Habitat
The species is reported to be endemic to Mexico, where Thorius salamanders are restricted to montane regions, often within pine‑oak or cloud forests at mid‑ to high elevations. Precise locality data, elevation range, and extent of occurrence for T. aureus are not comprehensively documented in publicly available sources.
Ecology and Behavior
General ecological traits of Thorius species include a fossorial or leaf‑litter microhabitat preference, nocturnal activity, and a diet consisting of small invertebrates such as mites and springtails. Specific studies on the ecology, reproductive biology, or diet of T. aureus have not been located.
Conservation Status
The conservation status of Thorius aureus has not been formally assessed by the International Union for Conservation of Nature (IUCN). Many Thorius species are considered vulnerable due to their restricted ranges and sensitivity to habitat disturbance, but the threat profile for T. aureus remains unverified.
Research and Knowledge Gaps
