Phyllophaga glaberrima

Phyllophaga glaberrima
Lancaster County, Pennsylvania, USA
July 5, 2010
Size: 19mm
What species it this? I think it is P. quercus. Everything matches, but I would like it confirmed.

I have keyed this out as best I can with these images. I am leaning towards P. glaberrima, but I do not have comparative material, and this species is not on BugGuide yet.

Based on these images, I cannot see the presence of a second (lower) spur on the hind tibia, which supports P. glaberrima. P. quercus has a noticeable lower spur (also, P. quercus has 9 antennomeres, and this specimen clearly has 10, so P. quercus is readily ruled-out).

Evidence for P. glaberrima is as follows:
-tarsal claws not narrowly cleft
-body not setose or pruinose
-clypeus emarginate
-antennae 10-segmented
-apparent lack of lower tibial spur (could just be angle of images, however).

This is the best I can do without specimen in-hand.

 
Thank you
These are very common where I found it. I made a forum for the new guide page.

 
I can make a guide page...
but do not think it should be done until confirmed.

 
the only hind spur i see is
the one the arrow points at. If I am not looking in the correct spot, please tell me.

 
Thanks!
This image is more convincing. I will move for now, pending other analysis! Thanks much!

 
That image
is just a scaled image of one of the other ones posted earlier.

I can try and key it out later tonight (my lit. is at home). These images should be good enough! Possibly not P. quercus (doesn't look pruinose).

 
Okay
Thanks! I'm horrible at identifying these. If you need any more pictures I still have the specimen.
