Taxonomy
- Kingdom: Animalia
- Phylum: Chordata
- Class: Amphibia
- Order: Caudata
- Family: Plethodontidae (lungless salamanders)
- Genus: Pseudoeurycea
- Species: Pseudoeurycea gadovii
- Authority: (Taylor, 1942)
Common name
- Frequently referred to as Gadov’s salamander.
Description
- A small to medium‑sized terrestrial salamander.
- Adult total length typically ranges from 6.5 cm to 9.0 cm (snout‑vent length plus tail).
- The body is slender with smooth skin; coloration is generally brownish‑gray with darker dorsal markings, though precise patterning can vary among individuals.
- As a member of Plethodontidae, it lacks lungs and respires through its skin and buccal cavity.
Distribution and habitat
- Endemic to Mexico.
- Known from the Sierra Madre Oriental in the Mexican states of Puebla and Veracruz.
- Occupies pine‑oak forests at elevations of approximately 1,800 – 2,500 m above sea level.
- Often found under logs, stones, and leaf litter in moist microhabitats.
Ecology and behavior
- Primarily terrestrial and nocturnal, emerging during periods of high humidity.
- Diet consists of small invertebrates such as insects, arachnids, and other arthropods.
- Reproduction is presumed to be direct development (eggs hatch as miniature salamanders), a characteristic common to many plethodontids; however, specific reproductive data for P. gadovii are limited.
Conservation status
- Assessed by the International Union for Conservation of Nature (IUCN) as Endangered.
- Principal threats include habitat loss and degradation due to logging, agricultural expansion, and infrastructure development.
- The species’ restricted range and dependence on specific forest habitats heighten its vulnerability.
Protection measures
- Occurs within several protected areas, including national parks and biosphere reserves in the Sierra Madre Oriental.
- Conservation actions recommended: habitat preservation, monitoring of populations, and research on life history traits.
