Sherborn: Thompson & Pape - Sherborn’s critical influence in getting information control over a megadiverse group

The order Diptera (Insecta), flies, is a megadiverse group, representing some 15% or more of the known species of organisms. Scientific names are tags to concepts (hypotheses), called species, by which we organize our knowledge of biodiversity. Our Systema Dipterorum provides an index to all scientific names related to flies, so access to our knowledge about them is readily available. Sherborn more than a century ago attempted to provide such an index to all animal names. He did provide an index to all names published up until and including 1850. We compare our indexes, revealing how standards have changed and the number of names increased. Today, more and better resources are being made available to us, such as the Biodiversity Heritage Library, and our standards are higher (new International Code of Zoological Nomenclature), but regardless of all the change, Sherborn for his time provided an almost perfect (99.9%) index.

- On this graph you can see the growth in the number of names and species through time. I have added the average number of species described per year. The early 19. century was very productive due to authors like Meigen and Wiedemann. Then there was an ebbing with only 417 descriptions per year. The pace picked up at the start of the 20. century, which was very productive with 1720 descriptions per year. World War 2 brought an end to this productive phase and since then the average growth is quite stable with 1345 descriptions.

- With which we have arrived today. Now, we have the BDWD, currently online as version 8.5. The nomenclator is about 90% done and holds over 191.000 species and 22.500 genus names. Of these 154.000 represent valid species and 11.700 valid genera. The references database includes more than 21.000 references. The nomenclator is a great tool for finding names and is the envy of entomologists working on other groups of insects. It is online available at ‘The Diptera Site’.
