In Europe their species number amounts to around 6000. Some species can be find everywhere in Europe, others are restricted to a small area. Especially blind cave beetles have mostly a very limited distribution area. There are often gaps in our knowledge of the distribution of a species. We try to give a survey of our knowledge.
Additions are welcome.
We ordered the data along political boundaries. This is not logically from the viewpoint of a beetle. Groundbeetles concerns with natural boundaries. But several entomologists publish from their country a catalogue. We used these catalogues to collect data of the distribution of a species throughout Europe.
