Pristimantis scopaeus is a species of frog in the family Craugastoridae. It is endemic to Colombia and occurs in the Cordillera Central in the Tolima and Quindío Departments. Pristimantis scopaeus is a dwarf species: adult males in the type series were first mistaken for juveniles of Pristimantis simoteriscus, which itself already is a small species. The specific name scopaeus is Latinization of the Greek skopaios, meaning dwarf.
