The paper presents an annotated checklist of 33 stonefly species from the Badzhalsky Nature Reserve, representing 7 families and 19 genera. This includes 15 species newly recorded for the reserve. The stonefly Isoperla chereshnevi Teslenko, 2017, is recorded for the first time in Khabarovsk Region, and Amphinemura palmeni (Koponen, 1917) is recorded for the first time in the Russian Far East. The fauna is predominantly composed of widespread East Palaearctic species (63 %). Its unique character is demonstrated by the presence of East Asian taxa inhabiting the northern limits of their ranges (13 %). Circumpolar and Trans-Palaearctic distribution types are represented by 17 % and 7 % of the species, respectively. This composition underscores the adaptability of rheophilic stoneflies to the harsh conditions of mountain rivers, and highlights the position of Badzhal Ridge as a biogeographic boundary for species of southeastern origin.
