Liomenochilus ongi new genus and new species (Coleoptera: Scarabaeidae: Melolonthinae: Systellopini) is described from the Kimberley Region of northern Western Australia, Australia. It differs from the other six genera of systellopines by its general shape and colour; by its antennae with eight antennomeres, including a 3-lamellate club; and by the labro-clypeal suture being effaced medially and present only at the lateral declivity. A revised diagnosis for the tribe and a revised key to the seven genera of Systellopini are given.
