ABSTRACT. Based on fresh and re-examined material from SW Siberia, the distributions of seven diplomaragnid millipede species have been supplemented, refined and updated. The following few taxonomic changes are proposed: Altajosoma bakurovi (Shear, 1990), stat. revalid. ex A. bakurovi bakurovi (Shear, 1990), Altajosoma bakurovi longiprocessum Mikhaljova, 2000 = A. longiprocessum Mikhaljova, 2000, stat.n. A. bakurovi (Shear, 1990) is recorded from the Republic of Khakassia for the first time, A. corniferum Mikhaljova, Nefediev et Nefedieva, 2008 is new to the Altai Province. A description of the posterior gonopods of A. deplanatum (Stuxberg, 1876), as well as the diagnosis of the genus in general are supplemented. The distributions of all Altajosoma species encountered are mapped.
