ZooKeys 626: 1–43. doi: 10.3897/zookeys.626.9681 Abstract Members of the family Siphonorhinidae Cook, 1895 are thread-like eyeless millipedes that possess an astounding number of legs, including one individual with 750. Due to their cryptic lifestyle, rarity in natural history collections, and sporadic study over the last century, the family has an unclear phylogenetic placement, and intrafamilial relationships remain unknown. Here we report the discovery of a second spe- cies of Illacme, a millipede genus notable for possessing the greatest number of legs of any known animal on the planet.
