The total species richness in the myriapod assemblages of the lowland Altais near Charyshskoe Village, Altai Province, southwestern Siberia, Russia is estimated to be at least 19 species from ten genera, eight families, five orders, and two classes. The following species are new to SW Siberia: Lithobius (Ezembius) ostiacorum Stuxberg, 1876, L. vagabundus Stuxberg, 1876, and L. (Monotarsobius) nordenskioeldii Stuxberg, 1876, while L. (E.) proximus Sseliwanoff, 1880 and L. (M.) insolens Dányi & Tuf, 2012 are recorded for the first time from the Altai Province of Russia. A species of Strigamia which is morphologically similar to Strigamia cf. transsilvanica (Verhoeff, 1928) has been found in the study area but its true specific identity is yet to be determined. The seasonal dynamics of myriapod assemblages in terms of the species diversity, density, sex-age structure, and vertical distribution along the soil profile have been studied with regard to the different slope exposures.

The geophilomorph centipede fauna of urban areas in southwestern Siberia comprises at least seven species belonging to four genera and two families. The following records are new to western Siberia (Geophilus flavus (De Geer, 1778)) or southwestern Siberia (G. proximus C.L. Koch, 1847 and Pachymerium ferrugineum (C.L. Koch, 1835)). The northernmost range limits are reported for Arctogeophilus macrocephalus Folkmanová et Dobroruka, 1960, Escaryus japonicus Attems, 1927 and E. koreanus Takakuwa, 1937, all lying in western Siberia. The distributions of all relevant species encountered in the region are mapped. РЕЗЮМЕ.

The anthropochore millipede fauna of Asian Russia is reviewed, based on the available literature records, as well as new samples from the Altai Province and only partly published, freshly revised material [Nefediev, Nefedieva, 2006, 2011]. The julid genus Brachyiulus Berlese, 1884, as well as B. jawlowskii Lohmander, 1928, are new to the millipede faunas of Asian Russia and Kazakhstan. The polydesmid genus Brachydesmus Heller, 1858 and B. superus Latzel, 1884 are reported from Asian Russia for the first time. Both the genus Poratia Cook et Cook, 1894 and P. digitata (Porat, 1889), as well as the family Pyrgodesmidae they belong to, are formally new to the millipede fauna of Russia. The subcosmopolitan Nopoiulus kochii (Gervais, 1847) is recorded in Kazakhstan for the first time. Remarks are provided for all of the anthropochore species of the study area, all being mapped as well.

Disphaerobius Attems, 1926, the sole constituent genus of the subfamily Pterygoterginae, is synonymized with Pterygotergum Verhoeff, 1934 syn. nov., and is shown to comprise only two species: D. svenhedini (Verhoeff, 1934) comb. nov. ex Pterygotergum, and D. loricatus (Sseliwanoff, 1881) (= Lithobius magnificus Trotzina, 1895), both syn. nov. and comb. nov. ex Lithobius Leach, 1814. Disphaerobius is rediagnosed, both of its basically Central Asian species are redescribed from fresh material of both sexes, and their distributions are mapped. Disphaerobius svenhedini is newly recorded from S Kazakhstan and W Mongolia. New material of D. loricatus is also recorded. Sexual dimorphic characters in Lithobiomorpha are briefly discussed, these being considered especially strongly pronounced and unique in Disphaerobius.
