Checklist of the Collembola: Key to the species of Uchidanura

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.

Rationale

The rationale for taxa used and not used as well as subtaxonomic classification for some taxa is to be provided.

Key

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

      Body length up to 8.0 mm; fourth antennal segment apically
        rounded; lobes present only on fifth abdominal segment;
