Agonum - Agonum punctiforme

Agonum - Agonum punctiforme
Oklahoma County, Oklahoma, USA
July 4, 2007
Size: 8 mm
A species of Agonum. I believe it to be Agonum punctiforme.

(Definitely keys to couplet 35 of Liebherr 1994.)

Close to Agonum punctiforme
as the (other) image does appear to show convexities lateral to hind pronotal pits sufficient to satisfy first part of couplet 35. However, it is best to use at least a 80X scope to study the kinds of dorsal microsculpture patterns which I consider most reliable for separating members of the punctiforme species group. Brad, I need a vacation from my 'taxonomic' frustrations in dealing with the inherent limitations of on-line carabid photography. I will be checking in now and then. Keep up the good carabid work! Peter

 
Thanks
Thanks for your insight on this and others. I've looked at the microsculpture and it conforms best with A. punctiforme. This is definitely a difficult genus!
