ABSTRACT. Data on the chironomid fauna (subfamily Chironominae) of the Anyuiskii Nature Reserve and neighbouring areas, based on a study of imaginal material are presented. The rivers and reservoirs within the nature reserve support 70 species belonging to 29 genera and two tribes. Three species new to science were found in the reserve and bordering territories: Polypedilum sp., Tribelos sp. and Tanytarsus sp. Their descriptions will be published in a separate article. Microtendipes shoukomaki Sasa, 1989 is recorded in the Russian fauna for the first time; it was previously known only from Japan. Fifty-four species were reported for the first time in Anyuiskii National Park. Of the 49 species that were identified, 34 (60 %) have a Palaearctic distribution and 23 (40 %) have a Holarctic distribution. The greatest diversity of non-biting midges of the Chironominae subfamily was recorded in the Anyui River basin rivers — 34 species, and in an unnamed pond near the ANP office in Troitskoye Settlement — 33 species. Fewer species of chironomids were found in the Gassi Lake basin: Pihtsa, Mulchu and Khar rivers — 17 species. Eighteen species were found in the watercourses of the Hutu River basin in the adjacent territory.
