Sigmocheir calaveras is the type species for the genus Sigmocheir and was described by Ralph V. Chamberlin in 1951 based on a sample collected by G. Moore from Crystal-Stanislaus Cave, Calaveras County in 1950. [2] The species has a distinctive trimaculate pattern with an ovoid mid-tergite yellow spot and yellow paranota. [2] The paranota on S. calaveras arise high on the tergites giving the millipedes a rather flat appearance. [2]
