The adult male frog is 4.1 cm long and the adult female frog is 4.3 cm long. Their front feet are not webbed and their back feet have only a little webbing. This frog digs in the ground to make a burrow, where it hides. This frog is gray-brown or olive-brown in color with a thin stripe in the middle of its back down its spine.[4]

This frog lives on flood plains near small streams. It comes aboveground after rain.[4] Scientists do not know what its tadpoles are like.[3]
