Checklist of the Collembola: Key to the species of Balkanura

This key is still under construction. Note that missing figures will be provided as soon as possible. Currently, the key is in the feasibility study phase to find out how to integrate in the checklist in a modular way a key that has been generated with DELTA.

Key

Note that no distinction between subtaxa and taxa is made in the key.
