# Nannaria

The genus Nannaria, commonly known as twisted-claw millipedes, is a genus of millipedes in the family Xystodesmidae first described by Ralph Chamberlin in 1918. In 2022, entomologists Derek Hennen, Jackson Means and Paul Marek discovered and described 17 new species, which expanded the size of Nannaria to 78, making it the largest genus of Xystodesmidae.
