Bufo trachypus Wiegmann, 1833 Bufo valliceps Wiegmann, 1833[2] Cranopsis valliceps (Wiegmann, 1833) Ollotis valliceps (Wiegmann, 1833) The Gulf Coast toad (Incilius valliceps) is a species of toad native to eastern and southeastern Mexico and Central America as far south as Costa Rica.

Their back is covered in small tubercles, while their underside is normally devoid of them.

I. valliceps has the most extensive ridging of any toad in its geographic range.

The Gulf Coast toad is found in a wide range of habitats, including open grassland, semi-arid regions, light forest, and even suburban backyards.

They are typically found not far from a permanent water source, which they use for breeding in the spring, but they are capable of travelling long distances while foraging for food.
