I have contacted Dr. Frans Jassens who promptly answered:
"indeed it is definitely Entomobrya.
I have 2 candidate species:
1. E. multifasciata
2. Female E. atrocincta
They are difficult to distinguish on habitus pictures. Were there any orange/black Entomobrya specimens found in the close neighbourhood? If yes: atrocincta, if no: multifasciata."
