A new genus, Anacanthobythites, is proposed for two previously unknown species of live-bearing brotulas collected in temperate Australia. The first, A. platycephalus sp. nov., is based on a single male taken in Lucky Bay, Western Australia. The second, A. tasmaniensis sp. nov., is based on two males taken off Port Davey, Tasmania. The new genus is characterized mainly by a depressed head; seven branchiostegal rays; the first branchial arch without developed gill rakers; the anteriormost anal fin ray located below dorsal rays 19-22; and the absence of palatine teeth, an opercular pore, and a pseudobranch. In most respects, both members of the new genus resemble species of Grammonus Gill, 1896 or Microbrotula Gosline, 1953.
