We present a comparison at the generic level of the cave Collembola fauna recorded around the world. Using the biogeographical provinces proposed by Christiansen and Bellinger (1995), we analyzed the similarity among regions according to the Collembola genera inhabiting caves. The European region is separated from the remaining biogeographical regions and one of the main groups includes the Asia Pacific region, North America, and the Arctic and Subarctic regions. This can be related to the differences in the distribution of the genera, and the wide distribution of some of them in the world. Some provinces share the same Collembola in spite of their great geographic distances, perhaps resulting from their geological origin or from the different collecting efforts in each region.
