Proposal of Karliella gen. n. for the Afrotropical ‘Pegomya’ sexpunctata Karl, 1935 (Diptera: Anthomyiidae), a possible kleptoparasite of dung-breeding beetles
The genus Karliella Michelsen, gen. n., is described to accommodate Pegomyia sexpunctata Karl, 1935 (syn.: Pegomyia abdominalis Emden, 1941). The peculiar morphology of Karliella makes it difficult to find a closer relationship to any particular anthomyiid genus or group of genera, which suggests that it represents the only extant member of an ancient lineage. The type species and only included species, Karliella sexpunctata (Karl, 1935), comb. n., appears to be locally abundant in dry and mesic woodland of Namibia and South Africa, but has also been found in Botswana and Zambia. The larvae probably develop in dung from large herbivorous mammals. The female has been observed laying eggs on newly formed, unburied scarab dung-balls, but whether this is customary behaviour is unknown.
