Hypogastrura harveyi
The new lens is paying off with good enough shots to get species id's on these small bugs. Thanks for the updates. Now I'll have to find some H. nivicola.

Hypogastrura harveyi
A close relative of H. nivicola. The nivicola-group comprises 4 species: nivicola, harveyi, simsi and tooliki.
Thanks to your new pictures, it is clear now that the dark indigo blue specimens (that I have IDed previously as nivicola) are in fact harveyi.
H. harveyi has much larger anal spines then nivicola. Typical for harveyi is that the antennae are a bit longer then the head diagonal. Also typical are the 2 basal subclavate (knob-like) antennal segments and the two cylindrical apical antennal segments.
Also, harveyi (2.5 mm) is a bit larger then nivicola (2.0 mm).
