Key to the beetle family Ptinidae published

After a long gap in my postings I thought I would restart with the new year.  Over the last couple of months I've been working on a key for the beetle family Ptinidae.  This has involved translating keys from the German and researching some of the species recently introduced to the British list not included in the German keys. The last thing was translating some descriptions from the Latin and Spanish which are added as appendices to the main key.  If you find the key useful then please let me know so I can improve it.  The key is published at https://sites.google.com/site/mikesinsectkeys/Home/keys-to-coleoptera/key-to-the-british-species-of-family-ptinidae.
