Springtails: Onychiurus or Folsomia?

They look the same to me. For Folsomia, I don't know what is meant by abdominal segments 4 to 6 are fused.

Onychiurinae
In Folsomia the last 3 body segments (= abdominal segments 4 to 6) are fused, as in 'ankylosed', as in 'grown together'.

One question.
I forgot to mention that these didn't jump. Does that help narrow down possible choices for genus? I have hundreds, if not thousands, of these in a potted plant so I can take more images if requested, but the quality will be limited to what has already been posted.

Onychiurinae
cannot jump given they do not have a furca. So the vernacular name 'springtails' cannot be applied to Onychiurinae. There are other springless springtails (such as Neanurinae). Best is to use the name 'Collembola': all Collembola have a collophore.
