Necatia is a genus of the jumping spider family Salticidae. Its only species, Necatia magnidens, is found in southern China. The species is only known from a single female specimen, collected in 1872 by A. David, and described by Schenkel almost a hundred years later. Nothing more has been reported of the species since.
