Glomeridesmida is an order of millipedes in the infraclass Pentazonia containing 2 families and at least 31 species. Glomeridesmida is the only living order of the superorder Limacomorpha. Glomeridesmidans are small (less than 15 mm (0.59 in)) and somewhat flattened, possess 22 body segments, and unlike other orders of Pentazonia, are unable to roll into a ball. Glomeridesmidans occur in the New World Tropics, Southeast Asia, India, and Oceania. Two species are known cave-dwellers, and, like other troglomorphic animals are translucent from loss of pigment. The five known species of Termitodesmus (constituting the family Termitodesmidae) have a commensal relationship with termites.
