An interactive species key will be presented here once data analyses are finalized, which will stay take a bit of time. For now I can only recommend to use the latest species keys by Seevers (1965) and Borgmeier (1961) - please contact me if you need help. 

As pointed out in the project objectives, however, species identifications are difficult with existing keys. It is my goal to provide a more easily usable, robust species key. For each step in the key, I will provide visual illustrations of characters by integrating a combination of drawings, high-quality 2-D images and 3-D models, exemplifying the differences of presented characters. For now I only present the characters allowing to sort specimens into four distinct Vatesus groups - a distinction suggested by Borgmeier and Seevers.
