Calianotus, n. gen., is proposed for three small California polydesmids in which the gonopodal tibiotarsus arises basally and the endomerite possesses a lateral branch and two shorter distal projections. Brachydesmus (Brachydesmus) yosemitensis Causey, occurring in the Sierra Nevada from Calaveras to Tulare counties, is the type species; Polydesmus sastianus Chamberlin is assigned to the representative occurring in the upper Sacramento River Valley, in the Mt. Shasta area of Shasta and Siskiyou counties; and Brachydesmus bituberculatus Loomis, occurring east of San Francisco Bay in Contra Costa and Alameda counties, is transferred into the genus. Calianotus is related to Scytonotus Koch; relationships within the genus are sastianus + (bituberculatus + yosemitensis). The identity of Phreatodesmus hastingsus (Chamberlin), plausibly referrable to Calianotus, cannot be assumed because the original illustrations are meaningless and the vial with the holotype now contains two different polydesmids, one of which occurs in Idaho. Topotypes are needed to determine its identity and generic placement.

In North America west of the Continental Divide, the milliped family Polydesmidae consists of six genera and 15 species, and occupies eight disjunct areas. Retrorsia, n. gen., is proposed for two new \“micro-polydesmid\” species (R. leonardi, the type species, and R. benedictae) in western Oregon and Washington, primarily in the lower Columbia River Valley. It is most closely related to Utadesmus Chamberlin and Hoffman, 1950, in Utah and New Mexico, and is characterized primarily by a retrorse gonopodal tibiotarsus that curves dorsad and counters the ventral curvature of the telopodal stem. New records are presented for the coastal species of Bidentogon Buckett and Gardner, 1968, occurring from Mendocino to Santa Cruz counties, California, and encompassing the area around San Francisco Bay. The oldest available name for this species is californicus (Chamberlin, 1918), whose type locality is Stanford, Santa Clara County. This name has been misapplied to the species occurring in Sacramento County, herein named B. expansus, n. sp., and B. helferorum Buckett and Gardner, 1968, is placed in synonymy under B. californicus.
