Taxonomic notes: This species was removed from the synonymy of Hylarana luzonensis by Brown, McGuire and Diesmos (2000), and it was subsequently moved from the genus Hylarana to Sanguirana by Fuiten et al. (2011).

This species occurs in the Central Cordilleras, on northern Luzon Island, in the Philippines. It has been recorded approximately between 850 and 950m asl (R. Brown pers. comm.).

It inhabits cool streams and rivers in montane rainforest, and is able to tolerate a small amount of disturbance. It presumably breeds in streams and lays its eggs in water.

It usually occurs in fairly good numbers in suitable habitat.

The most important threat to this species is the deforestation of lower montane and lowland forests in the Cordilleras. Montane forests are either being converted to vegetable farms or are being developed into real estate.
