A review of the holarctic genus tmeticus menge, 1868 (araneae, linyphiidae), with a description of a new genus

Abstract

Eight species attributed to Tmeticus are reviewed; five are redescribed and illustrated: T. affinis (Blackwall, 1885), T. bipunctis (Bösenberg & Strand, 1906), T. nigriceps Kulczyn ́ski, 1916, T. ornatus (Emerton, 1914) and T. tolli Kulczyn ́ski, 1908. The new genus, Paratmeticus gen. n. is erected for T. bipunctis, and a new combination is established: Paratmeticus bipunctis (Bösenberg & Strand, 1906), comb. n. Three species names: Gongylidium vile Kulczyn ́ski, 1885, syn. n., Tmeticus difficilis Kulczyn ́ski, 1926, syn. n. and. T. dubius Kulczyński, 1926, syn. n., are synonymized with T. tolli Kulczyński, 1908. Although G. vile has date priority over T. tolli it is synonymized because of the lack of usage. Three species from Japan attributed o Tmeticus: T. neserigonoides Saito & Ono, 2001, T. nigerrimus Saito & Ono, 2001 and T. vulcanicus saito & Ono, 2001 are not related to T. affinis, the type species of the genus, and their affinities remain unclear. The male of T. nigriceps is described for the first time.©Y.M. Marusik, S. Koponen.
