Isotomidae
For the larger species you can use this rule to distinguish Entomobryidae from Isotomidae : compare the lengths of abdominal segments 3 and 4.
If abd.3 = about abd.4 : Isotomidae
If abd.3 < abd.4 : Entomobryidae

Two different species?
Frans, the two specimens in the second image look different to me. I'd love to hear your thoughts.

Could be 2 species of Isotomidae...
or 2 specimens of the same species, 1 more macerated than the other perhaps...
