Babindellinae, a new subfamily of Dolichopodidae (Diptera) from Australia, with a discussion of symmetry in the dipteran male postabdomen

Abstract

Babindella physoura and B. whianensis gen. et spp. n., are described from Queensland and New South Wales, respectively. Babindella is distinctivc in having a symmetrical male postabdomen with the seventh and eighth segments fused, ands is regarded as the sole representative of a new dolichopodid subfamily, the Babindellinae. The development of symmetry in the diptcran male postabdomen is discussed.
