New genera of Australian stiletto flies (Diptera Therevidae)

摘要

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