Revision of the European representatives of the genus Callipallene Flynn, 1929

It will be difficult to imagine a more variable group of species than the European representatives of the genus Callipallene Flynn, 1929. He, who wants to identify the European species and sub-species of the genus Callipallene, may easily get stuck, for if he does not dispose of enough material for comparison, he will have great trouble in distinguishing them. Yet, though difficult to define, certain differences do exist between the forms. It must be pointed out that non-adult specimens are almost unidentifiable. With the aid of our drawings and descriptions, however, it will be possible to identify full-grown females and ovigerous males.
