RES handbook Vol 4 Part 9. Coleoptera (Pselaphidae)

This is the first "booklet" ever published dealing exclusively with the British Pselaphidae. In this family, following Jeannel and others, I have included our two British species of Claviger. This genus has often been regarded as sufficiently distinct to warrant the creation of a separate family, the Clavigeridae, to contain it and its allies. Many coleopterists now regard Claviger and its allies as very specialized but degenerate Pselaphidae. This view has much in its favour.
