Springtail - Ptenothrix

Springtail - Ptenothrix
Cowichan Valley, British Columbia, Canada
January 14, 2013
Size: ~1.7-2mm body length
Found under a piece of wood, feeding on the remains of another springtail. I think it's feeding, anyway.

What about Ptenothrix maculosa?

Are the big setae on the antennae of any significance?

Ptenothrix sp.
Could be maculosa, but this species is not well defined...
Else the undescribed P. sp.5 at

Interesting, thanks. Would close-ups of any particular parts make it possible to tell for sure? If so I'll try to include them in future sets.

To check for Ptenothrix maculosa ...
Your specimen match more or less with the drawing made by Schött (1891): dark antennae, facial pattern, dorsal pattern.
Check Schött's figure and try to make shots that may be compared with that figure.
