ABSTRACT: The genus Oreoneta Kulczyński in Chyzer et Kulczyński, 1894 is removed from synonymy with Hilaira Simon, 1884. The genus comprises 31 species of which the following 18 are new to science: Oreoneta banffkluane sp.n., O. beringiana sp.n., O. eskimopoint sp.n., Oreoneta eskovi sp.n., O. fennica sp.n., O. fortyukon sp.n., O.herschel sp.n., O.logunovi sp.n., O. magaputo sp.n., O. kurile sp.n., O. mineevi sp.n., O.repeater sp.n., O. sepe sp.n., O. tienschangensis sp.n., O. tuva sp.n., O. uralensis sp.n., O. vogelae sp.n., and O. wyomingia sp.n.. Also 12 new combinations are presented, all ex Hilaira species: Oreoneta alpina (Eskov, 1987) comb.n., Oreoneta arctica (Holm, 1960) comb.n., Oreoneta brunnea (Emerton, 1882) comb.n., Oreoneta frigida (Thorell, 1872) comb.n., Oreoneta garrina (Chamberlin, 1948) comb.n., Oreoneta intercepta (O. Pickard-Cambridge, 1873) comb.n., Oreoneta leviceps (L. Koch, 1879) comb.n., Oreoneta mongolica (Wunderlich, 1995) comb.n., Oreoneta montigena (L. Koch, 1872) comb.n., Oreoneta punctata (Tullgren, 1955) comb.n., Oreoneta sinuosa (Tullgren, 1955) comb.n., and Oreoneta tatrica (Kulczyński, 1915) comb.n. O. montigena arctica is removed from synonymy with O. frigida intercepta; O. punctata from that of O. tatrica; O. sinuosa from that of O. frigida. Status of the following taxa is elevated from subspecies to species level: O. arctica stat.n. (ex O. montigena a.), O. brunnea stat.n. (ex. O. frigida b.), O. garrina stat.n. (ex. O. tatrica g.) and O. intercepta stat.n. (ex. O. frigida i.). Neriene rudis O. Pickard-Cambridge, 1879 and Tmeticus niger F.O. Pickard-Cambridge, 1891 are moved from synonymy with O. montigena (L. Koch, 1872) and placed as junior synonyms of O. frigida (Thorell, 1872). The species are assigned to six species groups. The structures of the copulatory organs are discussed in detail and compared with the type species of Hilaira, Neriene excisa O. Pickard-Cambridge, 1871. Illustrations, diagnoses, descriptions and distribution maps are given for each species.
