AB: An inventory of the caddisflies of Gorkhi Terelj National Park, Mongolia, was undertaken in the summer of 1993. Adult and larval specimens were collected from 21 locations. Samples were taken from the Tuul River and its tributary streams during 5-11 July and from Yestiin Rashaan and Lake Khagiin Khar during 28-29 July. A total of 22 species of caddisflies, belonging to 16 genera and 12 families, were documented in this study. Four species are newly recorded for Mongolia, including Arctopora trimaculata (Zetterstedt), Micrasema gentile McLachlan, Ylodes levanidovae Morse and Vshivkova, and Goerodes sp. The most common species were Psychomyia flavida Hagen, Glossosoma nylanderi McLachlan, Glossosoma intermedium (Klap lek), Goera tungusensis Martynov, Rhyacophila egijnica Schmid, and Apatania majuscula McLachlan. Highest abundances were for species living in sand or stone habitats and making saddle cases or tube cases. Sites on the Tuul River, East Bayan River, Khokh Chuluut River, and Bayan River yielded highest abundances of specimens. Species richness was highest in the Tuul, Bayan, and East Bayan Rivers. These high abundances and richness data directly correlate to water temperature, amount of dissolved oxygen, and riparian vegetation (grasses, forbs, and shrubs).
