Pristimantis ridens

Pristimantis ridens, also known as the pygmy rain frog and the Rio San Juan robber frog, is a species of frog in the family Strabomantidae. It is found in western Colombia (Pacific slopes of the Cordillera Occidental), and then through Panama and Costa Rica to Nicaragua and eastern Honduras.

Description
Pristimantis ridens are small frogs, with males growing to 19 mm and females to 25 mm in snout–vent length. The dorsal skin is smooth and pale brown or yellow in colour, with some pink undertones. There is often a slightly darker W-shaped patch just behind the head. Individuals may have a single or two, parallel dorsolateral stripes. The thighs are barred. The ventral colouration is yellow with some dark specks.

Pristimantis ridens can be very similar to Pristimantis cruentus.
