Checklist of the Collembola: Key to the subfamilies of Entomobryidae

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). Fourth abdominal segment as long as or longer than 2 times sum
        of first to third abdominal segment.............. Paronellinae
      Fourth abdominal segment shorter than 2 times sum of first to
        third abdominal segment..................................... 2
 
2(1). Body scales absent................................ Entomobryinae
      Body scales present (fig.1).................................. 3

3(2). Dental spines absent............................... Willowsiinae 2
      Dental spines present............................. Entomobryinae 3


Endnotes

1 Soto-Adames et al. (2008) place Lepidosinella in Seirinae because Yoshii indicates that in scale and mucro morphology, and in general body shape Lepidosinella most closely resembles Seira. But according to Yoshii (1989), Lepidosinella lacks ventral dental scales and keys out to Willowsiinae in line with Zhang et al. (2014).

2 Although Zhang & Deharveng (2015) dismissed Willowsiini, for convenience, in this checklist, the tribe Willowsiini of Entomobryinae is maintained at subfamily level.

3 Scaled Entomobryinae such as Sinhomidia, Amazhomidia, Acanthocyrtus.


Differential diagnoses

Entomobryinae
Body scales absent. Fourth abdominal segment shorter than 2 times sum of first to third abdominal segment.

Entomobryinae 3
Body scales present (fig.1). Dental spines present. Fourth abdominal segment shorter than 2 times sum of first to third abdominal segment.

Paronellinae
Fourth abdominal segment as long as or longer than 2 times sum of first to third abdominal segment.

Willowsiinae 2
Body scales present (fig.1). Dental spines absent. Fourth abdominal segment shorter than 2 times sum of first to third abdominal segment.
