It is endemic to Chile and only known from its type locality, Río Lircay, in Alto de Vilches, Talca Province, on the western slopes of the Andes.

[1][3] The specific name hugoi honors Professor Hugo Campos Cereceda, for his "remarkable contributions to the development of the natural sciences in Chile".

There is no webbing but some membrane between the toes IV and V. The dorsal coloration is light brown with golden tints.

[2] Natural habitat of Alsodes hugoi is temperate Nothofagus forest at elevations of 900–1,200 m (3,000–3,900 ft) above sea level.

However, the species is protected by Altos de Lircay National Reserve.
