Central-Palaearctic temperate range: a central Asian species, L. insolens has very recently been found in the Omsk Area, Altai Province, and Republic of Altai ( Nefediev et al. 2017b , c , d ). Remarks. The above record of L. insolens , recently announced at the 17th International Congress of Myriapodology ( Nefediev et al. 2017c ), can be considered as the first formal record of the species in the Altai Province, SW Siberia. In the study area, the species has significant preference for the southern slope. A single ♂ with aberrant numbers of antennomeres (22+24 vs. 20+20 in original description) was found.
