Conk springtail - Ptenothrix marmorata

Conk springtail - Ptenothrix marmorata
Mt. Washington, Coos County, New Hampshire, USA
July 4, 2007
Size: about 2.3 mm
Found this unexcitable fellow on the underside of a conk I had just removed from a dead tree. I was impressed with his size. He held still while I advanced an open compartment of a plastic pill sorter toward him and hopped directly into the cubicle, sitting still while I closed the lid. To me it bears great similarity to members of genus Ptenothrix, so that is where I have placed it. This find was one of the many collateral benefits in my Forest Service-approved search for Py*tho str*ictus.

Ptenothrix marmorata
Well done, Jim. Ptenothrix species can be separated from other Dicyrtomidae by the distinct spiny setae on the 2nd antennal segment.
In these pictures the spiny setae on the body of this species are also well distinguished. Great shots. Given the max. size of this species is 2.5 mm, this specimen is clearly an adult.

 
Thank you, Frans.
I almost placed it in marmorata :-)

I have been passing on springtail opportunities left and right to concentrate more on coleopterans but I couldn't pass this one by.
