Taxonomic notes on dubious spider species (Arachnida: Araneae) from the Russian Far East
The taxonomic status of six spider species described by Grube [1861] and Strand [1907] from the Russian Far East is re-examined. Asagena amurica Strand, 1907 is not a synonym of Steatoda albomaculata (De Geer, 1778), but of Asagena phalerata (Panzer, 1801) (syn.n.). Attus dimidiatus Grube, 1861 is not a synonym of Carrhotus xanthogramma (Latreille, 1819), but possibly unknown female of Mendoza zebra (Logunov et Wesołowska, 1992); in the absence of type material the name remains a nomen dubium. Attus fuscostriatus Grube, 1861 is probably a senior synonym of Talavera ikedai Logunov et Kronestedt, 2003, but until conspecific material is found from the type locality, this identification will remain uncertain. Micryphantes miniatus Grube, 1861, Linyphia albomaculata Grube, 1861, and Linyphia melanopleuros Grube, 1861, currently cannot be identified based on their original descriptions, and previously suggested synonymies are unconvincing; these taxa are also relegated again to the status of nomen dubium.
