Polydesmida
Polydesmida (from the Greek ''poly'' "many" and ''desmos'' "bond") is the largest order of millipedes, with more than 5,000 species, including all the millipedes reported to produce hydrogen cyanide (HCN). This order is also the most diverse of ...

Many authorities now deem Fuhrmannodesmidae to be a
junior synonym
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The botanical and zoological codes of nomenclature treat the concept of synonymy differently.

This family includes three species (''

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 until reaching maturity, which occurs one moult earlier for 19 segments or two moults earlier for 18 segments.
