Abstract
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 Anabarhynchusoceanus sp. 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.
