ABSTRACT. Based on fresh and re-examined material from SW Siberia, the distributions of five diplomaragnid millipede species of Shearia Mikhaljova, 2000 have been supplemented, refined and updated. The range limits of the following species are expanded: S. khakassica Mikhaljova, 2000 is new to be recorded from the Republic of Altai, S. longa Mikhaljova, 2012 is reported from outside its type locality for the first time, whereas the distribution area of S. oiskaya Mikhaljova, 2000 is limited to the south of the Krasnoyarsk Province. Descriptions of the posterior gonopods of S. calycina Mikhaljova, 2000 and S. khakassica, as well as the diagnosis of the genus in general are supplemented. The distributions of all Shearia species encountered are mapped. A key to all known species of the genus is given.

KEY WORDS: Diplopoda, Diplomaragnidae, Shearia, fauna, new records, Siberia, Russia, Mongolia.
