of
millipedes belonging to the order
Polydesmida. The family includes over 50 genera. This family includes three species (''Hexadesmus lateridens'', ''Agenodesmus reticulatus'', and ''Eutynellus flavior'') notable for being among the very few species in this order to feature adults with only 18 segments (including the

This family also includes several genera (e.g., ''Cyclopsodesmus'', ''Cylindrogonus'', and ''Leigonopus'') notable for featuring

in segment number: adult females in these genera have the usual 20 segments, but adult males have only 19.
Millipedes in these species arrive at these lower numbers of segments by going through the same stages of
teloanamorphosis observed in other polydesmids but reaching maturity one moult earlier for 19 segments or two moults earlier for 18 segments.
