Checklist of the Collembola: Key to the superfamilies of Entomobryomorpha

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.

    
1(0). Body setae mostly ciliate; multilaterally ciliate macrosetae
        sometimes cylindrical (fig.1a) usually truncate (fig.1b) or
        broadened at the tip (fig.1c); scales absent or present..... 2
      Body setae usually smooth (fig.2a) or unilaterally ciliate
        (fig.2b); multilaterally ciliate macrosetae always acuminate
        (fig.2c); scales absent 1..................................... 3

2(1). Postocular bothriotrichum absent; abdominal segments 2-3 with
        0-1/1-2 bothriotricha............................ Tomoceroidea
      Postocular bothriotrichum present (fig.3); abdominal segments
        2-3 with 2/3 bothriotricha..................... Entomobryoidea

3(1). Third abdominal segment fused with fourth abdominal segment
        (fig.4)......................................... Coenaletoidea
      Third abdominal segment not fused with subsequent segment.......
         ................................................. Isotomoidea

Endnotes

1 Neophorella, a Tomoceridae so far known only from South Africa, will key out here, but it can be identified by having the fourth antennal segment shorter than the third, smooth dental spines, and an elongate mucro with two setae and four teeth aligned on the dorsal lamella.
