Pseudoeurycea robertsi

Females in the type series measured 35–51 mm (1.4–2.0 in) in snout–vent length; the sole male was 49 mm (1.9 in) in SVL. The tail is laterally compressed and almost equal to SVL or shorter. The head is broad, rather flattened, and with truncate snout. There is a broad, orange stripe on the back and tail. The limbs are well developed. The first digit is very short; there is no webbing.[3]

Pseudoeurycea robertsi is a terrestrial salamander living in pine-fir forests at elevations of 2,900–3,600 m (9,500–11,800 ft) above sea level. Specimens have been found under rocks, logs, and loose bark of fallen logs and stumps. It is relatively common but has declined in the past and has a small area of occurrence. Moreover, there are threats to its habitat from tourism, forestry, agricultural and livestock activities, and urbanisation: formerly a national park, Nevado de Toluca is now an Área de protección de Flora y Fauna, conferring a weaker conservation status.[1]
