Funding Information:
We are indebted to John McNeill and Werner Greuter for kindly answering our doubts before starting to write this proposal. We would also like to thank John McNeill and John Wiersema for their flawless editorial work. This proposal is a result of two grants (143/2013 and 22/2016) to IO, funded by the Swedish Taxonomy Initiative (Svenska artprojektet) administered by the Swedish Species Information Center (ArtDatabanken). A grant from the SYNTHESYS initiative funded a stay to examine collections kept in the Museum national d'Histoire naturelle of Paris (PC).
