Key for the identification of British Monotomidae

The latest checklist has 23 species in three genera and two subfamilies. They are quite small beetles most of which are associated with decaying plant material, either under the bark of dying or dead trees or in compost heaps or similar habitats. Two of our species are associated with ants' nests. The three genera are Rhizophagus and Cyanostolus in subfamily Rhizophaginae and genus Monotoma in subfamily Monotominae.
