New key to genus Cryptophagus published

I've just completed my translation and adaptation of a key for the British species of genus Cryptophagus.  This genus has a reputation amongst beetle-specialists of being one of the most difficult in our fauna.  If you experience any success with it or find that it fails at certain points please let me know.  You'll find the key at https://sites.google.com/site/mikesinsectkeys/Home/keys-to-coleoptera/cryptophagidae.
