Habitat

High-elevation montane environments are documented for multiple , with records from 1650–3960 m elevation in the Himalayas, Turkey, and Papua New Guinea. Some species occupy mesovoid shallow substratum (MSS) , as evidenced by collection using subterranean pitfall traps.

Distribution

Widespread across the Palearctic and Oriental regions, with documented occurrence in: Europe (Bulgaria, Montenegro), Turkey, the Caucasus and Middle East (Iraqi Kurdistan), Central Asia (Pakistan, Afghanistan), the Himalayas (Nepal, India, China), East Asia (South Korea, Japan, China: Yunnan), and Southeast Asia. The Pristosia shows disjunct distribution patterns across the Western, Central, and Eastern Himalayas.
