Checklist of the Collembola: Key to the genera of Oligaphorurini

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 antennal segment with apical vesicle; tibiotarsi with clavate chaetae in distal whorl............... Chribellphorura Fourth antennal segment without apical vesicle; tibiotarsi with acuminate chaetae in distal whorl........................... 2

2(1). Abdominal terga v and vi accreted dorsally; third antennal segment and fourth antennal segment are accreted; anal spines absent........................................... Archaphorura Abdominal terga v and vi are free; third antennal segment and fourth antennal segment are free; anal spines present....... 3

3(2). Furcal rudiment in a form of cuticular furrow or small fold... 4 Furcal rudiment in a form of finely granulated area (fig.1)..... ............................................. Dimorphaphorura

Fig.1.

4(3). Row mm with 2 mm3 - 6 setae; row mp with 4-7 setae, the external ones are macrochaetae; row ma with 4-6 setae; furcal rudiment with two dental setae d on the fold or posteriorly and three manubrial rows of setae behind them (fig.2)...... Oligaphorura Row mm with 4-6 setae; row mp with 4-5 setae, the external ones are macrochaetae; row ma with 4 setae; furcal rudiment with three rows of setae behind its posterior edge (fig.3)......... ................................................ Micraphorura
