Individuals are very small, around 5 millimetres (0.20 in) long and, 0.7 mm wide, with around 40 body segments. The color is brownish-yellow, with lighter-colored legs.

WIllacme is a genus of millipedes in the family Siphonorhinidae. It includes two species. Illacme plenipes was first described in 1928 from San Benito County, California, and rediscovered in 2005. In 2016, Illacme tobini was described based on a single male specimen collected in 2006 from Lange Cave, in Sequoia National Park, 240 km (150 mi) east of the known habitat for I. plenipes.
WIllacme plenipes is a siphonorhinid millipede found in the central region of the U.S. state of California. It has up to 750 legs. One of two known species in the genus Illacme, it was first seen in 1926, but was not rediscovered until 2005, almost 80 years after its discovery, by Paul Marek, then a Ph.D. student at East Carolina University and now at Virginia Tech.
WIllacme tobini is a species of millipede in the family Siphonorhinidae. It was discovered in California at Sequoia National Park in 2016. This millipede is part of the Illacme genus which contains only one other species known as the Illacme plenipes.
