Phylogenetic revision of Australian members of the Allomethus genus group (Diptera : Pipunculidae)

The Australian species of Allomethus and Claraeola are revised and include one described species, Claraeola erinys (Perkins), and five new species: Allomethus unicicolis sp. n., Claraeola cyclohirta sp. n., C. sicilis sp. n., C. spargosis sp. n., and C. yingka sp. n.. Claraeola hylaea (Perkins) is proposed to be a synonym of C. erinys (Perkins). A key to species is provided and male and female genitalia are illustrated. The Australian species are placed phylogenetically into a world context using available taxa within the Allomethus genus group. The phylogenetic relationships are discussed in light of a cladistic analysis involving 22 taxa and 60 characters.
