Abstract
The spider family Selenopidae Simon, 1897 consist of four genera, of which Selenops Latreille, 1819 has about 110 species in tropical to temperate regions around the world (Platnick 2007). The distribution of this genus in America is from Argentina and Paraguay in South America, northward through tropical and subtropical America to Florida, Texas, New Mexico, Arizona, and southern California in North America (Muma 1953). These spiders can be found in different habitats, from dry desert and chaparral to tropical areas. They are typically found under rocks and other objects on the ground, occasionally inside tree trunks, and between the bases of the leaves of tropical plants. They also occur in the entrances of caves, on flat surfaces and in narrow cracks and crevices. They are commonly found inside human habitations. Their flattened body allows them to slide into these cracks with very fast movements, which makes their collection in the field difficult. They are nocturnal and do not build webs (Muma 1953).
