Willowsia buski
Jim, look out for these quick runners/jumpers. If they escape from your delli box inhouse, they might settle for a colony under your kitchen-sink ;-)

Thank you, Frans. I wonder if these are juveniles also.
They are a half-millimeter shorter than the ones I posted last year and they seem to lack the "golden chain" encircling their lower abdomen.

Indeed, they are juveniles. Good point.
Willowsia buski is easily recognised: note the 'long' scales at the margin between the 3rd and 4th abdominal segment. Not visible in this particular shot, but distinctly visible in the last shot of this series.
