Notoxinae of the Australian Region are revised, with 42 species clas- sifi ed in single genus, Mecynotarsus LaFerté-Sénectère, 1849. In total, 31 spe- cies 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-Sénectère, 1849 is regarded as Afrotropical species described by mistake from Australia. The identity of Leptoprion Krekich-Strassoldo, 1914 is briefl y discussed.

and perhaps the most popular group of anthicid beetles. Its members can be easily recognized by the presence of the peculiar antero-dorsal horn on the pronotum. Other important characters of these horned anthicids are: head closely articulated with pronotum, its base more or less truncate with paired lateral occipital condyles for articulation with the prothorax; pronotum with lateral cervical notches for articulation with the occipital condyles of the head; apical margin of mandibles enlarged as a thick rim or fl ange; submentum extended as widely separated angular fl at plates, covering the base of the maxillae; aedeagus with phallobase, separate parameres, and free median lobe; ovipositor an amorphous simple membranous structure, with only distinct sclerotized styli (CHANDLER 1982, 2001; KEJVAL 2011a). Most of the above listed external characters of Notoxinae (if not all) represent synapomorphies that evolved in connection with their typical habits – burrowing into sandy or loose soils; for behavioural observations
