Nops is a genus of medium-sized caponiid spider native to South America, Central America, and the Caribbean islands. The genus currently counts 27 extant species plus one fossil in Dominican amber, but probably the real number of extant species is greater. Nops have a great richness on the Caribbean islands (14 species). Even species of Central America (4) and South America (15) are located in high proportion toward the area of the Caribbean Sea.
