Abstract. A review of the Holarctic genus Lophomma Menge, 1868 revealed that this genus includes only two species: L. punctatum (Blackwall, 1841) and L. vaccinii (Emerton, 1926) of 11 known before. Both Lophomma species are illustrated as well as all Nearctic species formerly treated in this genus. Status of L. stictocephalum Menge, 1868 (the generotype), treated as a junior synonym of L. punctatum, is discussed. Four Lophomma species have been synonymised: L. candidum Bцsenberg, 1902 syn.n. = Mioxena blanda (Simon, 1884); L. rufipes Bцsenberg, 1902 syn.n. = Typhochrestus digitatus (O. Pickard-Cambridge, 1872); L. umbilicatum Crosby & Bishop, 1933 syn.n. = Lophomma vaccinii (Emerton, 1926) and L. cognatum Holm, 1960 syn.n. = Lophomma vaccinii (Emerton, 1926). Four new combinations are suggested: Diphya albulum (Paik, 1983) comb.n. (Tetragnathidae), Diphya tanasevitchi (F. Zhang, Y. Zhang et Yu, 2003) comb.n. (Tetragnathidae), Ceratinops sylvaticus (Emerton, 1913) comb.n. and Silometopoides pingrensis (Crosby & Bishop, 1933) comb.n., all ex. Lophomma. Although “Lophomma” depressum (Emerton, 1882) is not related to the generotype it was left in Lophomma because its taxonomic position is not clear. Lectotypes are designated for Lophomma stictocephalum, L. pingrensis and L. sylvaticum.
