Two new stiletto fly genera of Agapophytinae (Diptera: Therevidae) are described from Australia. Sidarena gen. n. comprises six new species (Sidarena aurantia sp. n., S. flavipalpa sp. n., S. geraldton sp. n., S. hortorum sp. n., S. macfarlandi sp. n., and S. yallingup sp. n.) and is largely endemic to Western Australia. Zelothrix gen. n. is described based on two species; Z. warrumbungles sp. n. is a locally abundant species in Eastern Australia, while Z. yeatesi sp. n. is restricted to southwestern Western Australia. These sister genera are likely closely related to Taenogerella Winterton & Irwin and Actenomeros Winterton & Irwin.
