This species is known exclusively from La Picucha, the highest peak in the Sierra de Agalta in eastern Honduras. It occurs only above 2000 m elevation, in the wet cloud forest around the peak and in the short dwarf forest on the peak itself. It did not occur in multiple Winkler samples taken between 1500–1700 m on the same slope. Most collections are from sifted litter; two collections are workers that came to baits. The species was abundant, occurring in 80% of miniWinkler samples. This is a mountain top endemic threatened by climate change.
