Revision of Australian Species of the Genus Diaea (Araneae: Thomisidae) with Redefinition of Their Taxonomic Status

Abstract. The crab spiders of the genus Diaea from Australia are revised. All the known 30 species are redescribed and illustrated. The type species of the genus — Diaea dorsata (Fabricius, 1777) (distributed in Palaearctic) is also included into this study. All the former members of Diaea from Australia changed their taxonomic position as a result of transfer to other genera. Three new genera were established: Australomisidia gen. nov., Boomerangia gen. nov. and Lehtinelagia gen. nov. Twenty new combinations are proposed: Australomisidia cruentata (L. Koch, 1874), A. elegans (L. Koch, 1876), A. ergandros (Evans, 1995), A. inornata (L. Koch, 1876), A. kangarooblaszaki (Szymkowiak, 2008), A. pilula (L. Koch, 1867), A. rosea (L. Koch, 1875), A. socialis (Main, 1988), Boomerangia dimidiata (L. Koch, 1867), Cetratus caecutiens (L. Koch, 1876), C. circumlitus (L. Koch, 1876), C. rubropunctatus (Rainbow, 1920), C. tenuis (L. Koch, 1875), Lehtinelagia evanida (L. Koch, 1876), L. multopunctata (L. Koch, 1874), L....
