Admirable False Brook Salamander (Pseudoeurycea praecellens)
The Admirable False Brook Salamander is known exclusively from a single specimen that was found in 1954 (or 1940 according to other sources).
This very small species, which reached a total length of only about 6,5 cm, inhabited the tropical humid forest at a small place named as Hacienda El Potrero near the city of Cordoba, a city that since of course has largely increased its expansion.
The Admirable False Brook Salamander was never found since, despite intensive searches, and is most likely extinct.
