Distribution.

Southern Siberian boreal range with isolated Yenisei population: this species has previously been recorded in the Yenisei River area, Krasnoyarsk Province and Irkutsk Area (central and eastern Siberia, respectively) ( Zalesskaja 1978), also recently found in northern Mongolia ( Poloczek et al. 2016), Altai Province ( Nefediev et al. 2017c) and Republic of Altai ( Nefediev et al. 2017d).

Remarks.

The above record of L. ostiacorum , recently announced at the 17th International Congress of Myriapodology ( Nefediev et al. 2017c), can be considered as the first formal find of the species in SW Siberia. In the study localities, the species was found more frequently on N facing habitats.
