[email protected] ABSTRACT Numerous taxonomic changes in Oriental crab spiders are listed with justifications and suprageneric taxa are discussed at global level. Similar pattern of more than one inner cheliceral setae is found to be a synapomorphy for Borboropactidae, Stephanopidae and Thomisidae. The separation of Stiphropodidae as a valid family is confirmed. The polyphyly of Dietinae sensu Petrunkevitch, 1928 is confirmed and its tribes are listed in Thomisidae, Thomisinae (Dietini, Alcimochthini, and Amyciaeini) and Bomidae (Apyretini, Tagulini, Emplesiogonini, Mystariini, Porropini, and Talaini). Boliscini, new tribe of Bomidae is created for Boliscus Thorell, 1891 and Corynethrix L. Koch, 1876, and family group names based on Bomis L. Koch, 1874 without known female is discussed. A strange gnathocoxal process in all Boliscus spp. is described. The Stephanopine groups Phartini, Borboropactini and new tribes Cebrenninini, Angaeini and Geraestini are transferred to Borboropactidae Wunderlich, 2004, and Phrynarachnini, Stephanopoidini, and Hedanini to Thomisidae s.str. These transfers are based on similar structure of copulatory organs of both sexes, trichobothrial patterns of legs and several ultrastructural characters. Phrynarachne Thorell, 1869 with type species P. rugosus Latreille, 1804 is now included in the same tribe as Synema Simon, 1864. Senoculifer Balogh, 1936 from New Guinea is transferred from Philodromidae to Thomisidae and synonymized with Demogenes Simon, 1895. Xysticus palawanicus Barrion, 1995 is synonymized with Alcimochthes limbatus Simon, 1885 (Alcimochthini).
