Checklist of the Collembola: Key to the species of Paranura

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.

Endnotes

1 Due to lack of information, nalo Christiansen & Bellinger 1992, and schotti Womersley 1935 are not included in the key.

2 Paranura suenoi Yosii 1955 is excluded from Paranura and not included in the key because it has a blue colour, reticulations on the lateral parts of abd.5, and a complete abd.6.
