Can you find this well camouflaged frog in the leaf litter? I somehow did.

Phrynobatrachus plicatus is a medium to large sized species (males < 42 mm; females < 38 mm) characterized by an indistinct tympanum ("eardrum"), moderate webbing, and prominent X-shaped dorsal glands.
The belly is white, but the lower surfaces of the tibiae (lower hindleg) are covered in irregular, brown spots.
While the throat is somewhat pigmented in females, it is black with deep, lateral vocal folds in males.
Phrynobatrachus plicatus most resembles Phrynobatrachus auritus, but that species is slightly smaller (males up to 29 mm; females up to 35 mm), has a distinct tympanum, more webbing (only 1-2 phalanges free on digit IV), and less pigmention on the ventral side.
