Hylodes magalhaesi, or the São Paulo tree toad, is a species of frog in the family Hylodidae.

[2][3] Its natural habitats are subtropical or tropical moist montane forest and rivers.

[3] Scientists link the reduced population of this frog to habitat loss, including urbanization and deforestation.

In 2013, scientists reported the presence of the deadly chytridiomycosis fungus growing on some specimens.

[3] This frog's Latin name was given in honor of Dr. José Carlos Reis de Magalhães, who helped collect samples and perform studies.
