Two new species from small, exclusively Mesozoic, families of nematoceran Diptera (true flies) from the Purbeck Limestone Group (Berriasian) of Dorset, UK are described, namely Procramptonomyia zigzagensis sp. nov. (Procramptonomyiidae) and Ellia purbeckensis sp. nov. (Elliidae). The fossil evidence suggests that these two families, along with the extant Cramptonomyiidae, are closely related.
