Sigmocheir furcata is a species of millipede in the family Xystodesmidae. [1] The species in endemic to California and found in the foothills of the Sierra Nevada mountains. [1] [2]
Sigmocheir furcata was described by Rowland M. Shelley in 1995 based on samples collected by R. E. Graham from Williams cave in Calaveras County in 1963. [2] As with other members of the genus, S. furcata has a distinctive trimaculate pattern with an ovoid mid-tergite yellow spot and yellow paranota. [2] Compared to other members of the genus the paranota on S. furcata arise slightly lower on the tergites giving the millipedes a slightly more domed appearance. [2] The species has light colored/white legs and antennae, and the antennae are rather long, reaching back to the third tergite. [2]
This species is the northern most representative of the genus being found in the foothills of the Sierra Nevada mountains to the north and south east of Sacramento. [2] Individuals of the genus have been found in Placer, El Dorado, Amador, Calaveras,and Sacramento, counties. [1] [2]
