Taxonomic revision of the Australian Notoxinae (Coleoptera: Anthicidae)

Abstract: Notoxinae of the Australian Region are revised, with 42 species classified in single genus, Mecynotarsus LaFerté-Sénect?re, 1849. In total, 31 species are newly described: Mecynotarsus armifer sp. nov., M. auceps sp. nov., M. auripilosus sp. nov., M. bicornis sp. nov., M. bidens sp. nov., M. bidentatus sp. nov., M. bullatus sp. nov., M. canthariphilus sp. nov., M. centralis sp. nov., M. dearmatus sp. nov., M. exophthalmus sp. nov., M. fallax sp. nov., M. festivus sp. nov., M. grandior sp. nov., M. granulatus sp. nov., M. hirtipennis sp. nov., M. imitator sp. nov., M. iuvenis sp. nov., M. magelae sp. nov., M. mollis sp. nov., M. nobilis sp. nov., M. obesus sp. nov., M. parvulus sp. nov., M. pilbarensis sp. nov., M. pilicornis sp. nov., M. pusillus sp. nov., M. regalis sp. nov., M. setulosus sp. nov., M. speciosus sp. nov., M. weiri sp. nov. (all Australia), and M. excavatus sp. nov. (New Caledonia). Two new synonyms, Mecynotarsus concolor King, 1869 = Notoxus decemdentatus Pic, 1899, syn. nov., and M. hortensis Lea, 1922 = M. lateroalbus Lea, 1922, syn. nov., are proposed. Lectotypes are designated for Mecynotarsus amabilis Lea, 1895 and M. kingii MacLeay, 1872. A key to the Australian Mecynotarsus is provided. Notoxus australasiae LaFerté-Sénect?re, 1849 is regarded as Afrotropical species described by mistake from Australia. The identity of Leptoprion Krekich-Strassoldo, 1914 is briefly discussed.
