In their somatic characters, the two species of this genus are similar in nonsexual traits to the others described here, except that the metzonital tubercles carrying setae are generally lower and the surface of the metazonites of the midbody rings nearly smooth. The distinction lies in the gonopods

The genus is named for our late and much respected colleague, Rowland M. Shelley (1942–2018), one of the most productive millipede taxonomists of 20th and 21st centuries. He initiated the modern study of the small polydesmids of western North America with careful redescriptions of known genera and species and the description of
