This species was previously only known from a tiny area on the western slopes of the Cordillera Oriental of the Colombian Andes near Virolín in Santander Department, Colombia. It is now also known from the municipality of Mogotes, also in Santander Department (F.L. Meza-Joya pers. comm. August 2016), and Paramo de Iguaque in Boyacá Department (M. Rada pers. comm. August 2016). Its elevational range is between 1,606–2,400 m asl. It occurs in four threat-defined locations, and its extent of occurrence (EOO) is estimated to be 1,854 km2.
Habitat and Ecology
This species 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, in 2004, was reported to have declined dramatically since it was first discovered. In 2001, only two individuals were recorded in the entire year. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
The major threats to the species is habitat loss and degradation due to agriculture and livestock ranching, and mining.
This species occurs in the the Cachalú private reserve, Santuario de Fauna y Flora Guanentá Alto Río Fonce, and Paramo de Iguaque. At least the two last protected areas are well protected.
Further protection is required for the habitat outside of the protected areas.
Red List Status
Listed as Endangered because its extent of occurrence (EOO) is 1,854 km2, it occurs in four threat-defined locations, and there is ongoing decline in the extent and quality of habitat and number of mature individuals.
