In the Oravské Beskydy Mts. in the National Natural Reserves of Babia hora Mt. and Pilsko Mt. (northern Slovakia) are natural forest and near-natural forest stands in 8th (Piceeta s. lat. =Spruce) and in 9th (Pineta mugo s. lat. = dwarf pine) vegetation tiers (= altitudinal vegetation zones) (vegetation tiers according Plíva 1971, 1991, Holuša and Holuša 2008, 2010, 2011). During 1999–2000, psocids (Psocoptera) were studied from 6th to 9th vegetation tiers. In total, 1,113 adults and 42 larvae in 17 species were found. In 6th VT, 11 species were found (the following species were eudominant: Caecilius burmeisteri, Philotarsus picicornis and Caecilius flavidus), in 7th VT only 4 species (eudominant Philotarsus picicornis, Caecilius despaxi and Philotarsus picicornis), in 8th VT 10 species (eudominant Stenopsocus lachlani, Caecilius despaxi and C. burmeisteri) and in 9th VT 10 species (eudominant Caecilius burmeisteri, Lachesilla pedicularia and Stenopsocus lachlani). Taxocenoses of psocids in the Oravské Beskydy Mts. were evaluated by Detrend Corespondence analysis (DCA) and Divisive Cluster analysis (DvClA). Material was compared with other material from various vegetation tiers in the Western Carpathians Mts. Characteristic species combination of psocids of 9th VT was designated as follows: Lachesilla pedicularia – Caecilius despaxi – Stenopsocus lachlani.
