Description
editSigmocheir 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]
Range
editThis species occupies a central, and slightly overlapping range, with the additional representative of the genus. It is found in the foothills of the Sierra Nevada mountains west of Stockton and Modesto[2] Individuals of the genus have been reported in Amador, Calaveras, and Tuolumne counties.[1][2] The species is often, but not always found associated with cave environments.
