Sminthurus? - Sminthurus incisus

Sminthurus? - Sminthurus incisus
Soldotna, Headquarters Lake, Kenai Peninsula Borough County, Alaska, USA
July 29, 2011
This animal was collected from a black spruce muskeg, brought into the lab, and offered vegetation from its natural habitat. Here it was photographed in the lab feeding on Rubus chamaemorus, but in the field they seem to spend most of their time on Betula nana.

I posted a video of this individual chewing on this leaf at http://www.youtube.com/watch?v=7J10Lix_PZE.

Some time ago I had sent some these off to Dr. Richard Snider, who determined them to be Sminthurus sp. A. I think this corresponds to Sminthurus sp. A sensu Christiansen and Bellinger (1998).

Reference
Christiansen, K. A. and P. Bellinger. 1998. The Collembola of North America North of the Rio Grande. Grinnell College, Grinnell, Iowa.

Sminthurus incisus
Given it looks like the European S. viridis and C&B 1998 considers S. viridis records from northern America as S. incisus.

 
key
I'll try to run some of these through the key to Sminthurus in Christiansen and Bellinger (1998) to see if it ends up at Sminthurus incisus or Sminthurus sp. A. I would very much like to know what these are since they are ubiquitous in muskegs in our area.

 
Thank you!
Thank you. I have had some trouble trying to get a name on this animal.
