The spider genus Calileptoneta Platnick is revised and all species are described, diagnosed and keyed. A neotype for Calileptoneta californica (Banks) is designated and Calileptoneta sylva (Chamberlin & Ivie) is removed from synonymy with Calileptoneta californica (Banks). The female of Calileptoneta noyoana Gertsch and the male of Calileptoneta sylva (Chamberlin & Ivie) are described for the first time. Three new species are described: Calileptoneta briggsi, Calileptoneta cokendolpheri, and Calileptoneta ubicki. The morphology of Calileptoneta is discussed, and interpretive illustrations of male and female genitalia are provided. The natural history of Calileptoneta is presented with an account of the mating behavior for C. ubicki. The distribution of Calileptoneta species is discussed, and areas of endemism and potentially new Calileptoneta species are noted.
