Paeromopus
''Paeromopus'' is a genus of large cylindrical millipedes endemic to the U.S. state of California. All species exceed 10 centimeters (4 inches) in length, and the largest, ''P. paniculus, ''reaching 16.5 cm (6.5 inches) is the longest millipede species in North America.〔 The genus was named by German entomologist Ferdinand Karsch in 1881 and contains four species: three occupying small ranges in the Sierra Nevada mountains and one occupying a large range including the Sierra Nevada and much of Northern California to the Central Coast.
==Description==
''Paeromopus ''millipedes are long and cylindrical, measuring in length and up to 8 mm (0.3 in) wide, with 68 to 80 body segments. The body color in most is brown to black with bands of light brown or yellow, although some individuals are dark gray or bluish gray with indistinct bands. The legs are relatively long, and the first pair of legs in males is extremely reduced in size. Like other paeromopodids, species of ''Paeromopus'' have fine parallel grooves (striae or striations) on each body segment, giving a somewhat roughened appearance.〔
The simple eyes (ocelli) occur in two patches- one on each side of the head; each patch may include up to 31 ocelli of unequal sizes, arranged in rows.
