Range Known from the type locality, and from the La Perla-Rancho Somecla road on Mt. Orizaba, Veracruz, 1800-2000 m (E. O. Wilson).
Biology This species occurs in transitional tropical-temperate cloud forest. One colony collected at Rancho Cielo by P. S. Ward was in a rotten log. Another I found on Mt. Orizaba was under a large rock in hardwood forest dominated by Liquidambar and Carpinus, with a Cyafhea-melastome understory. Winged queens were present in a nest at Rancho Cielo on 23 July.
