title: New genera of Australian stiletto flies (Diptera, Therevidae).
abstract: Two new stiletto fly genera of Agapophytinae (Diptera: Therevidae) are described from Australia.Sidarenagen. n.comprises six new species (Sidarena aurantiasp. n.,Sidarena flavipalpasp. n.,Sidarena geraldtonsp. n.,Sidarena hortorumsp. n.,Sidarena macfarlandisp. n., andSidarena yallingupsp. n.) and is largely endemic to Western Australia.Zelothrixgen. n. is described based on two species;Zelothrix warrumbunglessp. n.is a locally abundant species in Eastern Australia, whileZelothrix yeatesisp. n.is restricted to southwestern Western Australia. These sister genera are likely closely related toTaenogerellaWinterton & Irwin andActenomerosWinterton & Irwin.
