A new genus and species of the millipede family Altajellidae from eastern Kazakhstan, Central Asia (Diplopoda: Chordeumatida)

Considering the discovery of a new millipede genus and species, Tarbagataya splendida gen. and sp. nov., described from the Tarbagatay Mountains in eastern Kazakhstan, the small, Central Asian to South Siberian family Altajellidae is somewhat redefined, with a key compiled to all of its four currently known genera and species. The new genus is characterized by lack of male tarsal papillae, of coxal glands in male legs 11, and of flagella on the gonopods, by the particularly strongly modified male legs 7, by the especially lamellose and filamentigerous anterior gonopods, by the particularly reduced posterior gonopods, etc.
