Caponiidae is a family of ecribellate haplogyne spiders that are unusual in a number of ways.

Their phylogenetic relationships have long been enigmatic, but in the early 1990s it was determined that they are probably a sister group of the Tetrablemmidae plus the four families inside the superfamily Dysderoidea.

The species name is in honor of Harrison Ford, recognizing his efforts on behalf of the American Museum of Natural History.

The Chilean caponiid fauna differs from that of the rest of the Neotropics in lacking members of the Nopinae (named after the genus Nops).

Three genera newly described by Norman I. Platnick in 1994 were thus named Notnops, Taintnops and Tisentnops, emphasizing this fact.
