This species occurs in rain forest and cloud forest habitats, from 550–1420 m elevation. All specimens are from Winkler samples of sifted leaf litter. At three cloud forest sites in Nicaragua it occurred in 5-10% of 100 miniWinkler samples. In Costa Rica, it is known from one collection near Turrialba, a site on the Atlantic slope of the Cordillera Volcánica Central, yet is unknown from the intensively sampled Barva Transect a short distance away.
