Phrynomedusa fimbriata Miranda-Ribeiro

Spiny-knee Leaf Frog (Phrynomedusa fimbriata)

The Spiny-knee Leaf Frog was described in 1923, it is known exclusively from the type specimen, a female that apparently was collected in 1898 somewhere in the Paranapiacaba District in the state of São Paulo, Brazil.

This single specimen reaches a size of 4,6 cm and is now in very bad condition with completely faded colors, it is said to have been pale blue dorsally and reddish yellow on the ventral side. [1]


Two additional species within this genus are also known exclusively from their type series, thus, the Spiny-knee Leaf Frog might in fact not be the only extinct species in this genus. [1]
