Sonson Frog (Atopophrynus syntomopus)  

This species, a small reddish brown frog, was described in 1982, it is known only from three specimens.  

The Sonson Frog was found near Sonsón, a municipality in the Cordillera Central, in the Department of Antioquia, Colombia. The species inhabited wet rocks near a stream in primary forest at an elevation of about 2780 m, this locality, however, is now highly degraded due to guerilla activities.  

The Sonson Frog was never found again since its description and is very likely extinct.
