The Heterostygninae are found in the Lesser Antilles, and the Stygninae live from north of the Tropic of Capricorn (central South America). Most species live in the Amazonian rainforest. However, half the species have only been collected once, so distribution of species is poorly known.
See the List of Stygnidae species for a list of currently valid described species.
