LepIndex is the digitised card index of the Lepidoptera unit of the British Museum of Natural History, London. This database provides comprehensive information regarding the taxonomic histories of all Lepidoptera. If you need to clarify the author and year of description of any Lepidoptera, this is the place you need to visit. The database content is accurate – as one would expect from the BM(NH) – but not always precise. For example, year of publication was found to be inaccurate for a number of Sphingidae.
Nil required, knowledge of Lepidoptera systematics is helpful.
