Costa Rica, Trinidad, Brazil, Amazonian Bolivia. In Costa Rica: mid-elevation Atlantic slope.
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).
trinidadensis occurs in wet forest habitat in Costa Rica. It is known from arboreal foragers on low vegetation.
