Lysapsus is a genus of frogs in the family Hylidae found in South America east of the Andes.

[1] Many frogs in Lysapsus have a paradoxical life cycle.

They are most massive when they are older tadpoles and slightly smaller when they are adult frogs.

[2] There are four species:[1][3] The status of Lysapsus bolivianus is unclear; it might be a subspecies of Lysapsus limellum.
