A systematic review of the spiders of the family Nesticidae from North America, Central America, and the West Indies is presented with analyses of their features and relationships. The sedentary nesticids spin small tangled webs in dark places beneath ground objects, in leaf and other detritus, in underground spaces, and especially in many parts of caves. Three genera and more than 50 species are now known from the area under consideration. The exclusively American genus Gaucelmus, with five species, ranges from our southeastern states and Texas southward through Mexico and much of Central America. Most Gaucelmus are cavernicoles, but only one species, cavernicola of Jamaica, is somewhat modified by cave existence.
