Siphonorhinidae
Siphonorhinidae is a family of millipedes in the order Siphonophorida, characterized by super-elongated trunks with more than 180 diplosegments and leg counts exceeding 710 in some species. The family includes the leggiest animal on Earth, Illacme plenipes, with females possessing up to 750 legs. Members are small, threadlike, slow-moving, unpigmented, and inhabit deep soil microhabitats. The family exhibits a fragmentary, disjunct distribution across California, southern Africa, Madagascar, the Malay Archipelago, Indo-Burma, and now Chile. Siphonorhinidae is represented in the Western Hemisphere solely by the genus Illacme in California and the newly described genus Notorhinus in Chile.
