It is done by taxonomists (in this case Werner Kotz of Austria and Andreas Karge). Crusta 10 is the loose group who has taken responsibility for figuring out the taxonomy of many of the shrimp. Crusta10 is a consortium of people working on freshwater invertebrate taxonomy and biology. In short, a group of scientists study the shrimp and give them real names and classifications,w hich can be charted and documented so that people stop assigning names based on appearance and so that the discover of new species are recorded. They do field studies and collection trips and collaborate with hobbyists, importers, and breeders.
