We describe a new species of Cycloramphus from Ribeirão Grande in the Atlantic Forest of the State of São Paulo, Southeastern Brazil. The new species is characterized by the presence of an inguinal gland in adult males, feet not webbed, smooth skin, relatively small eyes, and massive jaw adductor muscles. The general aspect of body, conferred by a combination of a relatively short body and hind limbs, reduced eyes, and the massive aspect of head, suggests fossorial habits. Based on these characters, the new species is presumed to be closely related to the Cycloramphus bolitoglossus group, previously allocated to the genus Craspedoglossa.
