Sigmocheir is a genus of millipede in family Xystodesmidae. The species of this genus are endemic to California where they are found in foothills of the Sierra Nevada mountains. Individuals of the genus can be found from Placer County, south to the northern portion of Tulare County.
== Description == The genus is quite unique in appearance amongst the West Coast Xystodesmids. All three species in the genus have a similar color pattern with three lemon yellow spots on each segment (the paranota on either side plus a slightly wider central spot). The paranota arise high on the segments giving the millipedes a rather flat appearance.
