Ptenothrix sp.

Changed my mind. Again... ;-)
I realised it only after looking more carefully at both images... I was confused by the white 'eyecaps'...
This specimen belongs to the group of species hidden under Ptenothrix maculosa. This species is not well defined and is probably a complex of several species. Currently we have put such specimens tentatively as Ptenothrix indet5 at collembola.org
So your original classification in Dicyrtomidae was correct!

Thanks for your kind permission, John.

Ptenothrix sp. 3?

Frans, I'm wondering if this is a good match for what you've more recently described as sp.3?

Indeed it is, Harsi.

Good point! More precisely it is form 1a of sp.3.
It reminds me somehow at Metallica,
so we could call it forma metallica ;-)

Vesicephalus sp.

Not Dicyrtomidae but Katiannidae.
Note the large white tubercles inbetween the eye clusters.
