Resumen:
The family Palpimanidae is a small assemblage of spiders recognized by the coriaceous carapace, haplogyne genitalia, two spinnerets and especially, by the first pair of legs having dorsally enlarged femora and greatly developed prolateral scopula on tibia, metatarsus and tarsus. Palpimanids do not construct any sort of web snare, living mainly in the leaf litter of the tropical and subtropical forests, although several genera are known from dry habitats. Araneophagy was reported for many species. Palpimanids belong to the superfamily Palpimanoidea, a superfamily with diffuse limits, which may include certain families with very diverse morphology and habits. Nevertheless, there is no doubt of the close relationships between Palpimanidae, Stenochilidae and Huttoniidae. Three subfamilies are recognized (Palpimaninae, Chediminae and Otiothopinae), of which Otiothopinae is the only recorded in the New World. Fifteen genera were described in all the World (with 127 species), from which three genera (with six species) are known from Argentina. One additional species placed in Palpimanus is of doubtful procedence.
