Isotominae
Indeed. Could be Isotomurus, Isotoma or Desoria. to distinguish these genera you need to check the distribution of the dorso-lateral macrosetae on the body.
Isotomurus : macrosetae only present on posterior segments (abd.4-6)
Isotoma : macrosetae present on all segments
Desoria : macrosetae absent
Note : only to be used for adult specimens
Note2 : macrosetae may have been lost
Note3 : macrosetae are not always resolved in low resolution shots

Thank you!
Very helpful information -- I'll try to ensure that any photos in the future are of high enough resolution to distinguish this.
