It is endemic to Colombia and is only known from the eastern slopes of the northern Cordillera Central in the Antioquia Department.

[3][4] The specific name is derived from Greek zophus, meaning "darkness" or "gloom".

It refers to the drab coloration of this frog, as well as its habit of becoming active after the sunset.

It is nocturnal and usually encountered perched on very low vegetation, no more than 1 m (3 ft) above the ground.

It has been recorded in the Distrito de Manejo Integrado Cuchilla Jardin Tamesis, a regional protected area.
