ABSTRACT: Several species described in Keyserling’s 1886 ‘Die Spinnen Amerikas’ from Alaska have been declared by Roewer [1955] as nomena dubia. The type specimens of those species were examined and nomenclatural notes are made on Alaskan species described by Keyserling including the species Erigone usurpabilis Keyserling, 1886 syn.n. = Collinsia caliginosa (L. Koch, 1879), Erigone urusta Keyserling, 1886 = Oreoneta urusta (Keyserling, 1886) comb.n. = Hilaira montigena arctica Holm, 1960 syn.n., Erigone vacerosa Keyserling, 1886 = Styloctetor vacerosus (Keyserling, 1886) comb.n. = Styloctetor lehtineni Marusik et Tanasevitch, 1998 syn.n., Linyphia arctica Keyserling, 1886 (nomen oblitum) = Tenuiphantes mengei (Kulczyński, 1887) (nomen protectum), Erigone famularis Keyserling, 1886 = Tibioploides famularis (Keyserling, 1886) comb.n. = Tibioploides pacificus Eskov et Marusik, 1991 syn.n. Linyphia arctica Keyserling, 1886 was found to be a senior synonym of Tenuiphantes mengei (Kulczyński, 1887), but to lack of usage, and prevailing using of Lepthyphantes mengei or Tenuiphantes mengei (over a thousand times) we are applying to ICZN to protect junior synonym and declare senior synonym as nomen oblitum. Additional nomenclatural notes are also made on Erigone umbraticola Keyserling, 1886 = Improphantes complicatus (Emerton, 1882), Erigone schumaginensis Keyserling, 1886 = Kaestneria pullata (O. Pickard-Cambridge, 1863), and Erigone ululabilis Keyserling, 1886 = Oreonetides vaginatus (Thorell, 1872). Distribution of three species is mapped: Oreoneta urusta, Styloctetor vacerosus and Tibioploides famularis.
