The white-sand terrestrial nest-building frog (Adenomera albarena) is a frog. It lives in Brazil. Scientists think it could also live in Colombia.^[1][2][3]

The adult male frog is 21.2–23.0 mm long from nose to rear end and the adult female frog is 22.1–24.3 mm. The adult male frog has dark spots on his throat. Each frog has red color on the throat and the bottoms of the legs. Each frog has a dark stripe under each front leg. The frog's face has brown and pale gray color with some sky blue near the mouth. The eardrum is dark in color at the edge and lighter brown in th emiddle. The skin of the frog's back is brown. There are white bumps on the back nearer to the rear end. There is an orange stripe on part of the backbone.^[3]

Scientists named this frog albarena for two Latin words: alba for "white" and arena for "sand."^[3]

This frog only lives in places with white sand. Scientists found it near the West Negro River and Solimões River. Scientists have seen these frogs in a protected place, Rio Negro Sustainable Development Reserve.^[3]

The male frog sits on the ground or in the dead leaves on the ground and calls to the female frogs. Male frogs and young frogs are easy to find, but adult female frogs are hard to find. The male frog digs a hole in the ground and the female frog makes a nest out of bubbles in the hole. The male frog sometimes digs the hole under the dead leaves on the ground or near palm tree roots or fern roots.^[3]

The frog only lives in one kind of place, which means that human beings could change its home through pollution, cutting down too many trees, digging for good rocks in the ground, and letting animals eat grass.^[3]
