It is fully accepted that many of the older keys are now ‘out of date’ and should not be used for identification purposes. They can however, provide a useful service in allowing a better understanding of the species concept involved in some of the older species names recorded on the FRDBI. They can also provide an insight into the development of the taxonomic understanding of particular genera
