Moved from Springtails and allies. Moved to family for now. Hopefully you and Frans will be able to get it all the way to species!

Hypogastruridae or Pseudachorutinae

To decide : could you upload a frontal shot in which we could see whether or not the mouthcone is pointed.
If pointed : Pseudachorutinae.
If round: Hypogastruridae.
Also a shot of the anal segment is usefull: if anal spines are present : Hypogastruridae. If absent : Pseudachorutinae.

more shots

Thank you for your help! I have added some additional images, although I am not sure I have captured what you are looking for. Your web page is interesting; if I understand it correctly, this would be a Hypogastruridae. Let me know if I should provide additional shots, there are many individuals still hopping around in my refrigerator.

Hypogastruridae

Thx for the extra shots.
Indeed Hypogastruridae.
Now I would like to know the genus. First we will check for Ceratophysella.
1. Are anal spines present? A lateral shot of the anal segment will do. 2. Number of ocelli in the eyepatch? 8? Or less?

Anal spines present. It looks like 9 ocelli to me.

Hypogastrura manubrialis

is the best match.
Note 8 ocelli (a group of 5 anterior ocelli + a group of 3 posterior ocelli).
As a kind of confirmatory check: look for the post antennal organ. It is located just in front of the most anterior ocellus. It is about 2 times the size of the nearest ocellus and has 4 lobes.
