It is our mistake that the Acknowledgements in the original version did not include Jean-Claude Dauvin, Jean-Philippe Pezy, Benoit Gouillieux, Guy Bachelet, Karsten Reise, and Jonas Geburzi, who kindly provided us with European H. takanoi specimens. We do thank them deeply, and here we correct the Acknowledgements with our apologies.
