Venezuela, Panama, Costa Rica. Costa Rica: mid-elevation northern Cordilleras.
Strumigenys humata Lattke and Goitia 1997:385-386, Figs. 35,44. Holotype worker: Venezuela, Aragua: Loma de Hierro, 10deg10'N 67deg08'W, 25.5km SE La Victoria, 1400m (J. Lattke) [MIZA].
Brown and Wilson (1959) summarize the genus as follows:
"Widespread in tropics and warm temperate areas. Primarily forest-dwelling; some species occur in grassland and arid scrub. ... Nests mostly in soil and rotting wood; a few species live in arboreal plant cavities in tropical rain forest. Foraging hypogaeic to epigaeic-arboreal. Food: most species are collembolan feeders; a few are polyphagous predators or occasionally feed on sugary substances..."
Members of the genus are all predaceous, with a kinetic mode of attack (Bolton 1999).
This species inhabits wet forest leaf litter. Lattke and Goitia (1997) discovered the species in a cloud forest site in the interior of Venezuela. This report and Bolton (2000) extend the range to montane cloud forest sites in Costa Rica and Panama. This species is probably widespread but undersampled.
