Xystodesmidae is a family of millipedes. Its members often have very small distributional areas, with many species only known from a single locality.[1] They are found across the northern hemisphere, with peak diversity in the Appalachian Mountains, where one-third of the 300 or so species occur.[2] They are particularly abundant in deciduous broadleaf forests in the Mediterranean Basin, Africa, Asia, Central and North America, and Russia.[2] Information on basic taxonomy is scant for this family; for example, it is estimated that the genus Nannaria contains over 200 species, but only 25 have so far been described.[2]
The family is divided into the following tribes:[3]
