Checklist of the Collembola: Key to the species of Spinotheca

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). Dens with 11 anterior setae; distal antennal macrosetae with
        rectangular surface structure...................... patagonica
      Dens with fewer than 11 anterior setae; distal antennal
        macrosetae with spiral surface structure.................... 2
 
2(1). Anterior dental chaetotaxy 1 - - - 1 1 2 3............... cyanea
      Anterior dental chaetotaxy 1 - - 1 1 1 3 3......... magnasetacea

Differential diagnoses

cyanea
Anterior dental chaetotaxy 1 - - - 1 1 2 3. Dens with fewer than 11 anterior setae. Distal antennal macrosetae with spiral surface structure.

magnasetacea
Anterior dental chaetotaxy 1 - - 1 1 1 3 3. Dens with fewer than 11 anterior setae. Distal antennal macrosetae with spiral surface structure.

patagonica
Dens with 11 anterior setae. Distal antennal macrosetae with rectangular surface structure.
