Males usually have horn-like spinules in the dorsum; females are shagreened.

[2] Pseudophilautus viridis is a habitat generalist that occurs in both open and closed-canopy vegetation, including cloud forests and adjacent man-made habitats, at elevations of 1,555–1,830 m (5,102–6,004 ft) above sea level.

They are arboreal, found some 1 to 5 m (3 to 16 ft) above the ground, or in closed-canopy habitats, in the top stratum.

[1][2] The eggs are deposited in a deep hole in the forest floor that the female excavates.

[1] It is an uncommon species whose habitat is declining because of encroachment by tea cultivation and human settlements.
