Key for the identification of British Latridiidae

The current checklist includes 56 species in 13 genera and 2 subfamilies. Some of the species are very difficult to differentiate partly because they are so small, being only 1-3 mm. The attached file is a first go at the family in the UK, translated from the German keys published online by A. Lompe. It leads to most species, but there are three that I couldn't find characters for differentiation.
