As one of the most prominent mountain systems on Earth, the Tibeto-Himalayan Region (THR), is not only famous for its geographic and climatic influence at a global scale but is also well-known for harboring high levels of biodiversity and it presently comprises two global biodiversity hotspots. To explain the formation of the rich biodiversity in this area, the “Mountain-Geobiodiversity Hypothesis (MGH)” proposes that the present-day montane biodiversity patterns are derived from a combination of geology, biology, and climate change. However, validations and refinements of the hypothesis for a broader taxonomic spectrum are missing, particularly from animals. Trichoptera, colloquially known as “caddisflies”, is the largest order of primary aquatic insects. Caddisflies occur on all continents except Antarctica and have adapted to virtually all forms of freshwater ecosystems, including high-altitude streams, rivers, and lakes. Caddisflies of the genus Himalopsyche (Rhyacophilidae) are mainly distributed in the ...
