In order to keep track of the ever changing butterfly names, we are working on a "Taxonomic database" for butterfly names.
Here:
http://www.nymphalidae.net/taxon_db/
We are generating LSIDs for each butterfly name, including basic info such as the original combination of names from primary literature, list of synonyms and/or homonyms if they exits, type localities, some collection localities and a map when suitable.
We are working on generating RDF files for keeping this info readable for computers as well.
So far we have made available a checklist function for reporting species names according to Biogeographic region and family-level classification. We are on the works to finish up the search function.
