This species is known only from a tiny area on the western slopes of the Cordillera Oriental of the Colombian Andes, near Virolín, in the department of Santander, Colombia, at 1,740-2,400m asl.
Habitat and Ecology
It occurs on vegetation in the undergrowth of cloud forests, and can only be found in old-growth forest. It reproduces by direct development.
It is a very uncommon species that has declined dramatically since it was first discovered. In 2001, only two individuals were recorded in the entire year.
The major threat to the species is habitat loss and degradation due to agriculture and livestock ranching.
It occurs in the Santuario de Fauna y Flora Guanentá Alto Río Fonce and the Cachalú private reserve.
