In the city of Chernihiv, nematodes of epiphytic mosses were studied for the first time. 40 nematode species belonging to 30 genera, 20 families and 8 orders were revealed. Most of the identified species belonged to the order Rhabditida: 12 species or 30 % of total number. Nematodes of the order Plectida were the most abundant in the studied communities, they composed 61.21 % of total specimens collected. Nine species: Plectus parietinus (Bastian, 1865) Paramonov, 1964, Mesodorylaimus bastiani (Butschli, 1873), Geomonhystera villosa Butschli, 1837, Tylocephalus auriculatus (Butschli, 1873) Anderson, 1966, Aphelenchoides composticola Franklin, 1957, Panagrolaimus rigidus (Schneider, 1866) Thorne, 1937, Eudorylaimus circulifera Loof 1961, Plectus parvus (Bastian, 1865) Paramonov, 1964, Laimaphelenchus penardi (Steiner, 1914) Filipjev et Sch. Stek., 1941 constituted the core of nematode communities in epiphytic mosses.
