Adult head structures of Deuterophlebia coloradensis were examined, 3-dimensionally reconstructed and described. The results are compared to those of other representatives of basal dipteran lineages, primarily Nymphomyia dolichopeza (Nymphomyiidae) and Edwardsina gracilis (Blephariceridae). The head structures are extremely simplified. The labrum, mandibles, maxillae and labium are completely reduced. Only eight pairs of muscles are present. These modifications are possibly linked with the… CONTINUE READING
