Аннотация:New members of the spider family Caponiidae from Brazil and Chile are presented. Three new species in previously known genera are described: Taintnops paposo sp. n. from Chile, and the Brazilian Tisentnops mineiro sp. n. and Tisentnops onix sp. n., both belonging to a genus known only from its damaged type. Additionally, two new non–nopine Brazilian genera are proposed: Nasutonops gen. n. including three new species: N. chapeu sp. n., N. sincora sp. n. and N. xaxado sp. n.; and Carajas gen. n., known only from the type species C. paraua sp. n. Both new genera have entire, rather than sub-segmented tarsi. Therefore, they are not included in the caponiid subfamily Nopinae. Nasutonops gen. n. is characterized by the presence of a projected clypeal horn, unique among caponiids. Additionally, the first blind caponiids are described: Tisentnops mineiro sp. n. from the state of Minas Gerais and Carajas paraua sp. n. from the state of Pará. Both of these species are found only in caves and completely lack eyes.
