New genera of Australian stiletto flies (Diptera, Therevidae)

Two new stiletto fly genera of Agapophytinae (Diptera: Therevidae) are described from Australia. Sidarenagen. n. comprises six new species (Sidarenaaurantiasp. n., Sidarenaflavipalpasp. n., Sidarenageraldtonsp. n., Sidarenahortorumsp. n., Sidarenamacfarlandisp. n., and Sidarenayallingupsp. n.) and is largely endemic to Western Australia. Zelothrix gen. n. is described based on two species; Zelothrixwarrumbunglessp. n. is a locally abundant species in Eastern Australia, while Zelothrixyeatesisp. n. is restricted to southwestern Western Australia. These sister genera are likely closely related to Taenogerella Winterton & Irwin and Actenomeros Winterton & Irwin.

A new species of Anabarhynchus (Diptera: Therevidae) from an ocean beach in south east Victoria

Anabarhynchus Macquart 1848 is a large genus of the Therevidae (Diptera) that are endemic to Australasia with a couple of described species from Melanesia. We describe and illustrate Anabarhynchusoceanussp. n., a species found on ocean beaches in eastern Victoria, Australia. The species shares most characters with the monobasic Anabarhynchuskampmeierae species group of Lyneborg (2001), but also shares a unique feature of the male genitalia with the endemic New Zealand genus Megathereva Lyneborg, 1992. This new species brings the total number of described Australian species in the genus to 113.
