Distribution.

Eastern European-transSiberian temperate range: this species is widespread from the eastern Russian Plain (republics of Mari El and Tatarstan, Kirov and Samara areas) in the west through Siberia to the Russian Far East (Maritime Province, Sakhalin and the Kuriles) ( Zalesskaja 1978; Farzalieva and Esyunin 2008; Farzalieva 2009; Farzalieva and Tselishcheva 2009).

Remarks.

The above find of the species, recently announced at the 17th International Congress of Myriapodology ( Nefediev et al. 2017c), can be considered as the first formal record of it in the Altai Province, SW Siberia. In the investigated area, L. proximus is very rare and shows no significant differences in its distribution between slopes.
